Since May 2020, Iberian killer whales in the Strait of Gibraltar have interacted unusually with pleasure boats, posing significant maritime safety challenges. Recognized as critically endangered by the IUCN, a conservation plan for these whales has been approved in Spain. This study analyzes media coverage of these interactions, as media can shape public opinion and influence policies regarding human–wildlife conflicts. A total of 107 news articles published between June 2022 and September 2024 in Spanish media were examined, focusing on the interactions between Iberian killer whales and boats. The research included six variables from prior studies to enhance understanding of media representation and its effects on conservation management. Findings suggest that media coverage often limits comprehension of orca behavior and their vulnerable status. Keywords: media; news; marine ecosystem; cetaceans; Iberian killer whale; information 1. Introduction In the Anthropocene era, interactions between humans and wildlife are increasingly inevitable [ 1 ] as a result of various factors, such as the transformation and fragmentation of natural habitats [ 2 ], population growth and technological advancements [ 3 ], climate change, the recovery and reintroduction of species [ 4 ], and the increasing demand for nature tourism [ 5 ]. As a result, the literature on human–wildlife conflict, interaction, and coexistence has expanded rapidly, reflecting the growing importance of understanding these dynamics in contemporary conservation efforts [6]. This phenomenon has also been observed in the marine environment. Marine industrialization processes, which include maritime transport, seismic surveys, the installation of offshore wind farms, tourism, aquaculture, recreational fishing and other fishing activities, increase human activity at sea and thus also increase the number of interactions that occur with ocean fauna [ 7 , 8 ]. Studies that have investigated this topic have reported an increase in interactions between humans and various species of marine animals, such as pinnipeds [ 9 ], cetaceans [10], sharks [11] and turtles [12]. In recent years, interactions involving a small group of orcas (Orcinus orca) have received considerable interest from the public. Orcas, commonly known as orcas or killer Conservation 2025,5, 54 https://doi.org/10.3390/conservation5040054
Conservation 2025,5, 54 2 of 14 whales, is a cosmopolitan apex predator belonging to the family Delphinidae. As the largest oceanic dolphins, these marine mammals are distributed throughout all the world’s oceans [ 13 ]. They display varied social behaviors, from breaches and spy-hops to playing with objects and engaging in socio-sexual displays. Their communication combines echolocation and pod-specific calls, with some shared repertoires that maintain cohesion and reduce inbreeding risk [14]. The group of orcas involved in the interactions consists of fewer than 50 individuals, which exhibit distinct characteristics compared to other groups of killer whales in the Northeast Atlantic [ 15 ]. This population is commonly located in the Strait of Gibraltar and the Gulf of Cádiz, although they move along the Atlantic coast of the Iberian Peninsula following the migrations of their main source of food, i.e., bluefin tuna [ 16 ]. The study of molecular markers, ecological indicators, and photo-identification data indicates that these whales are a distinct group within the same species, separate from other populations in the Northeast Atlantic [15]. Starting in 2020, some individuals of this group of Iberian killer whales began to approach boats while they were sailing and to ram them on the hull or at the helm [ 17 ]. These events have taken place in the Strait of Gibraltar and, subsequently, along the Portuguese coast and in Galicia. These interactions have been repeated, and the number of encounters between killer whales and sailboats or small pleasure boats has come to exceed half a thousand. Some of these events have caused significant damage to such vessels, mainly due to breakage and disablement of the rudder; however, on a very small number of occasions, such incidents have caused these vessels to sink [18]. This behavior is unprecedented among orcas, and the scientific community has not provided a definitive explanation of the factors that motivate these mammals to interact with boats. Three main hypotheses have been proposed in this context. On the one hand, the origin of this behavior may be related to cetaceans’ past traumatic experiences, such as being struck by a boat or seeing the hit against another animal [ 19 ]. A second explanation posits that the boats could act as play stimuli that orcas use to develop the motor, cognitive and cooperative skills that they use in their hunting activities [ 20 ]. A third hypothesis proposes that the emergence of this behavior among killer whales could be the result of a combination of various factors, such as the stress generated by increased maritime traffic in their habitat, the competition with the fisheries for tuna and the reduced availability of prey. Finally, the fact that orcas are animals that have the ability to learn and reproduce behaviors based on the experiences of others cannot be overlooked; thus, mutual influence and learning due to social interaction are relevant elements of orcas’ behavior that should also be taken into consideration in this context [15]. Investigations of the factors that drive Iberian killer whales to interact with vessels reveal that this situation entails a potential danger for navigation in the Strait of Gibraltar and the Atlantic coast of the Iberian Peninsula, even though there is no record of humans being attacked by orcas in their natural habitat. This concern is further highlighted in Martel’s research, which includes surveys and interviews with sailors and other stakeholders that revealed sharp contrasts in perceptions and responses to the Iberian orca–vessel interactions [ 21 ]. Sailors overwhelmingly framed the encounters as problematic, with 38% describing them as “attacks,” and most expressed negative emotions such as fear or anxiety. Safety was their dominant concern (87%), but many also worried about orca welfare (85%). Nearly all reported behavioral changes, including altered navigation routes, avoidance of affected waters, or the use of deterrents. By contrast, other stakeholders—such as researchers, fishers, whale-watch operators, and marina staff—more often characterized the issue as minor or “not a concern”. This divergence underscores that the phenomenon is not
Conservation 2025,5, 54 3 of 14 only ecological but also a social conflict, driven by mismatched risk perceptions, emotional responses, and differing priorities among user groups. In this context, it is important to highlight the fact that the news concerning environmental issues disseminated by media outlets has a significant influence on public’s opinion regarding such interactions between humans and wildlife [ 22 ]. In this way, media coverage that emphasizes the anecdotal and particular aspects of these interactions can help spread a reductionist vision of the various relationships of mutual dependence among different species that coexist within an ecosystem [ 23 ]; furthermore, this interpretation can influence environmental policies pertaining to the species involved [ 24 ]. Similarly, the disproportionate informational attention that negative incidents involving wild animals receive (in comparison with encounters that do not lead to such consequences) can distort people’s perceptions of the real frequency of harmful interactions between humans and wildlife [ 17 ]. In addition, when information regarding such conflicting interactions between humans and animals is deficient or incomplete, this situation can facilitate the spread of feelings of fear and misconceptions regarding the species involved in these interactions, thus helping fuel the conflict itself [ 25 ]. However, the media can also help promote positive views of the relationship between humans and wildlife, particularly by highlighting the roles that such species play in the process of shaping people’s well-being on the basis of the services that they provide within the ecosystem and disclosing responsible coexistence practices [26,27]. Therefore, the task of analyzing the information that the media disseminates regarding the unusual behavior on the part of Iberian killer whales is relevant since it allows us to investigate the processes by which public opinion is formed. This aspect influences the management efforts made by administrations responsible for the conservation of this species, which is included in the Red List of Threatened Species of the International Union for Conservation of Nature and Natural Resources and is classified as vulnerable in the Spanish Catalogue of Threatened Species (CEEA) [ 28 ]. In accordance with this general purpose, the specific objective of this study is to analyze the information concerning interactions between Iberian killer whales and recreational vessels. This analysis will focus on news items available in the Spanish press and digital media from June 2022 to September 2024. 2. Materials and Methods 2.1. Sample The search for news pertaining to the behavior of Iberian killer whales took place between 1 July 2022, and 30 September 2024, through the digital newspaper library service MyNews www.mynews.es (accessed on 23 September 2025). MyNews [ 29 ] is a digital press archive and media monitoring platform that focuses on Spanish news sources. It offers tools for clipping, analyzing, and managing media information across print and digital media formats. This newspaper archive has been effectively used to examine the information disseminated by Spanish media on important social issues. These include climate change [ 30 ], palliative care [ 31 ], vaccine hesitancy [ 32 ], ageism [33], and the perceived safety of dietary supplements [34]. The search for informative pieces was performed during the first week of October 2024 by reference to a total of 792 examples of digital media, 537 publications in the press and 182 magazines and news agencies. News items were selected by applying the following search terms and operators: orca OR (ballena asesina) OR (Orcinus orca). The term ‘ballena asesina’ is the Spanish translation of the term ‘killer whale’. The initial collection of news items that were obtained by the procedure described above consisted of 980 informative pieces. The following exclusion criteria were applied to this collection of news items:
Conservation 2025,5, 54 4 of 14 1. News items that did not specifically address the behavior of Iberian killer whales were omitted. Thus, reports pertaining to the following topics were excluded: • News items that offered only general information regarding the behavior of killer whales or that exclusively addressed aspects pertaining to the survival of the species or information regarding the importance of the killer whales in the marine ecosystem. • Killer whale sightings in other geographic contexts that were unrelated to Iberian killer whales. • References to encounters with divers or people who were swimming or paddling. •Information regarding orcas in captivity. • Information concerning trademarks that included the word orca in the names of their products. 2. Repeated news items were discarded, and only the oldest item was considered valid. News pieces were considered repetition if they presented the same headline and text in the body of the news. 3. News items that were not published in Spanish or in any of the official autonomous languages in Spain were also omitted from this research. Finally, each of the informative pieces of which final sample is composed satisfy the following inclusion criteria: 1. News items that referred specifically to the behavior of Iberian killer whales, even if this topic was not the central issue addressed by the news items in question. 2. News items that had not previously been published. 3. News items that were published by a communication medium located in Spain, in the Spanish language or in one of the other official state languages and must be accessible between 1 July 2022, and 30 September 2024. The final sample was reduced to a total of 107 informative pieces that met the exclusion and inclusion criteria described above. In the Supplementary Materials, a complete list of the news included in the analyzed sample is presented (see File S1). 2.2. Variables and Categories To conduct a quantitative analysis of the news items included in the sample, six nominal qualitative variables were defined in line with previous research. Descriptions of these variables, the categories associated with and the justification for these definitions based on previous studies are provided below. In the Supplementary Materials, a table that summarizes the descriptions of the type of information and the corresponding contents of each category is presented (see Table S1 in File S2). Variable 1:Event Details. This variable focuses on identifying the details of the interactions that occurred between killer whales and boats in this context. Six categories have been identified in this context based on the work of Esteban and collaborators [ 15 ]. The first category refers to references in these news items to the type of vessel involved in the orca events, such as sailboats, fishing boats, inflatable boats, motorboats or others. The second category addresses references to the locations at which such interactions between orcas and vessels occurred, such as the Strait of Gibraltar, Peniche, Algarve, southern France and the waters of Galicia. The third category focuses on news items that referenced various forms of boat damage, such as rudder problems, hull damage or sinking. The fourth category refers to information pertaining to the behavior of killer whales, for example, how the approach to the boat occurred, the way it was contacted or the conclusion of the interaction. The fifth category addresses information regarding the speed of the interaction. Finally, the
Conservation 2025,5, 54 5 of 14 sixth category refers to the inclusion of the number of interactions that had occurred by the time of publication of the information in relevant news items. Variable 2:Explanations of Behavior. This variable pertains to the information provided in news items concerning the possible factors that, according to the scientific literature on this topic, have led orcas to interact with vessels. Four categories were defined based on the work of López and Methion [ 20 ] and Esteban and collaborators [ 15 ]. The first category pertains to explanations that suggest that some type of aversive incident or trauma in the past could encourage the Iberian orca to behave in this manner towards boats. The second category addresses explanations related to the game, suggesting that the incidents caused by the killer whales’ interactions with the boats are manifestations of their playful behavior, in which context the boats serve as play stimuli for these cetaceans. The third category focuses on explanations related to the cognitive and social capacities of orcas, including by highlighting aspects such as their learning capacity, communication among these mammals, the social bonds that they can form or the possibility that this behavior is a manifestation of the curiosity that characterizes these animals. Finally, the fourth category focuses on the idea that the behavior of killer whales towards boats is the result of a combination of factors that negatively affect killer whales, such as prey depletion, boat interference or orcas’ interactions with fisheries. Variable 3:Preventative Actions. This variable refers to an analysis of the information provided by news items regarding potentially useful strategies for managing the interactions between orcas and vessels and mitigating the associated risks. The first category associated with this variable refers to the recommendations that are mentioned in news items concerning individual actions that the people with responsibility for the boats should take to avoid risky situations involving killer whales. These recommendations pertain to various aspects, such as the type of navigation, schedules, speed and ways of handling the wheel. The definitions of the following two categories refer to the works of Scuderi [ 35 ] and Esteban’s team [ 14 ], who focused on technical solutions (such as radio alerts or temporal and spatial management tools), and regulatory changes (for example, an extension of the critical navigation zone for cetaceans to the east, the development of plans for areas of seasonal exclusion in the bay between Algeciras and Gibraltar or the prohibition of coastal navigation for small sailing boats during certain periods). Regarding the fourth category included in this variable, Esteban and co-authors [ 15 ] also highlighted the need to promote scientific studies that can improve our understanding of the behavior of these cetaceans and thus promote the implementation of risk reduction plans. In this context, López and Methion [ 20 ] highlighted the need to obtain detailed information regarding the movement patterns of killer whales in the context of efforts to facilitate the effective management of maritime traffic and ensure the conservation of this population, which is in danger of extinction. Finally, another category has been identified, in which other types of possible solutions that can be referenced in the news can be included. Variable 4:Threats. This variable is related to an examination of the information published in news items regarding the risks faced by orca populations. Relevant texts have indicated that the most relevant threats in this context include exposure to pollutants, the consequences of climate change, acoustic disturbances, collisions with ships and a decrease in fertility alongside the increased mortality observed among young individuals of this species [ 36 , 37 ]. Consequently, the information presented by the news articles included in the current sample regarding the threats faced by orca populations is categorized into the following three groups in accordance with the previously mentioned studies. The first category pertains to habitat disturbances, which encompass the presence of pollutants and waste in the environment, the overuse of resources, the impacts of climate change, and the availability of prey. The
Conservation 2025,5, 54 6 of 14 second group relates to the risks associated with maritime traffic, such as collisions and noise pollution. Lastly, the third group addresses additional threats to orca populations, including issues regarding their reproductive rates and assaults on these cetaceans. Variable 5:Legal Status. This variable is related to efforts to analyze the information contained in the articles included in the sample that pertain to legal protection and conservation regulations that impact orca populations. The definitions of the corresponding categories are based on the descriptions provided by Alessia Scuderi’s work [ 35 ]. Thus, the first category refers to whether the news items in question indicate that the species is included in the Red List of Threatened Species of the International Union for the Conservation of Nature (IUCN). The second category focuses on whether these articles mention any of the international conventions that protect this species, such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the International Convention for the Regulation of Whaling or the Bonn Convention. The third category is related to whether the information analyzed in this context refers to any regulation or law of the states that are involved in the conservation of the Iberian killer whale, for example, the Conservation Plan for the orcas of the Strait and Gulf of Cádiz [ 28 ]. Finally, an additional category has been identified, it focuses on whether the article mentions, even in a general way, the fact that orcas are a protected species and that they are at risk of extinction. Variable 6:Information Sources. This variable focuses on an analysis of the citations, testimonies or references mentioned in news items with the aim of supporting the information presented in them. The definitions of the categories associated with this variable were determined based on the classification proposed by Santos and Crowder [ 38 ]. The first category assesses whether the news includes any reference to authorities that research the behavior of cetaceans, including both professionals who are affiliated with universities and experts from organizations that are dedicated to the tasks of researching and conserving marine biodiversity. The second category addresses the inclusion of quotations from institutions, public bodies or international organizations that are competent in the field of marine conservation in these informative pieces. The third category refers to the inclusion of testimonies or statements of fishermen or crew members of sailboats and pleasure boats as well as specific mentions of these individuals. Finally, the fourth category includes appointments to private companies that are related to the tourism or fishing industry. 2.3. Concordance Analysis The analysis of agreement between the human coders was conducted using a procedure similar to that employed by Santos and Crowder [ 38 ]. The researchers who were responsible for the study jointly analyzed 20% of the news items included in the sample (N = 22) with the aim of aligning the study criteria with the variables and the corresponding categories described above. The remaining informative pieces were analyzed independently by both researchers. With respect to this last set of news items, the level of agreement between the human coders was evaluated based on Krippendorff’s alpha [ 39 ] regarding each of the categories associated with the 6 variables investigated in this study. 3. Results The section on the results of this research is divided into three parts. First, an analysis of the level of agreement observed between the evaluators who analyzed the news items included in the sample is presented. Subsequently, the results of an analysis of the six variables included in this research are presented. Finally, a synthesis of the results obtained from an analysis of the news is provided.
Conservation 2025,5, 54 7 of 14 3.1. Analysis of the Level of Agreement Between Human Coders The analysis of the level of agreement between the two evaluators regarding the 26 categories associated with the 6 variables under study in this research, revealed Krippendorff alpha values that ranged from 0.850 to 0.990. These results indicate a high level of agreement between the two evaluators. The results of a concordance analysis are available in the Supplementary Materials for this article (see File S3). 3.2. Analysis of the Proportion of News by Category for Each Variable 3.2.1. Variable 1: Event Details In the sample under analysis in this context, 89.7% of the articles (N = 96) offered information concerning at least one of the categories associated with this variable, which was related to the details of the encounters between orcas and vessels. In addition, among the entire set of articles, 25.2% (N = 27) addressed only one category, whereas 51.4% (N = 55) presented data concerning two or three categories. Finally, 13.1% (N = 14) provided information regarding four or more categories. With respect to specific information concerning the characteristics of the events associated with Iberian killer whales, 70.1% of the news items (N = 75) mentioned the type of vessel involved. Such a mention could be included in a general way, such as by indicating whether these vessels were sailboats or pleasure boats or by specifying their length. In addition, 57.9% of the informative articles under investigation (N = 62) offered some geographical reference regarding the place or places at which the events occurred, 43% (N = 46) indicated the damage that the killer whales caused to the boats, and 32.7% (N = 35) offered an account of the events that occurred. Only 10.3% of the news (N = 11) offered data regarding the behavior of the killer whales involved in this context (for example, how they approached the boats or how different individuals acted) or a residual number of news reports concerning the speed of the boats. A summary of the relative frequencies of the categories associated with the variable Event Details is available in the Supplementary Materials (see Table S2 in File S4). 3.2.2. Variable 2: Explanations of the Behavior of Killer Whales A total of 43% of the news items under analysis (N = 46) mentioned at least one possible cause of the behavior of these Iberian killer whales. Among all the news items under investigation, 14% (N = 15) presented a single explanation, whereas 29% (N = 31) addressed two or more possible causes of the behavior of these cetaceans. In relation to the explanations referenced in the articles under analysis in this context, the behavior of the killer whales could be related to the curiosity of these mammals or to some type of playful activity in which the youngest members of this species engaged. These points were mentioned in 32.7% of the articles (N = 35). Allusions to incidents, accidents or traumas that killer whales could have suffered in their past interactions with boats as a possible cause of the behavior of these cetaceans appeared in 23.4% of the news items (N = 25). In addition, references to orcas’ learning ability, their communication skills or the social bonds they tend to establish within the group were made in 23.4% of the informative pieces (N = 25). Finally, two informative pieces referred to the pressure or stress generated by a combination of factors. A summary of the relative frequencies of the categories associated with the variable Explanations of Behaviour is available in the Supplementary Materials (see Table S3 in File S4). 3.2.3. Variable 3: Preventative Actions A total of 47.7% of the news items under analysis (N = 51) mentioned at least one solution to the problem caused by encounters between killer whales and boats. Among the total set

In terms of the type of solution mentioned in the articles, 32.7% of the news items included in this research (N = 35) provided specific information regarding the behavior of people with responsibility for the boats that could help mitigate or prevent encounters with orcas. Strategies related to consideration of the area and the speed of navigation, the type of navigation (motorized or sailing), the most appropriate schedules for avoiding killer whales and the actions that should be taken in the event of a collision were highlighted. A total of 14% of the news items (N = 15) referred to technical solutions that could be used either to change the behavior of the killer whales (for example, through sound devices or accessory elements located at the helm) or to monitor cetaceans and provide information to vessels regarding the location of these animals. In addition, 8.4% of the news items (N = 9) referred to regulatory solutions, legal changes or the implementation of prohibitions related to navigation. A similar number of informative pieces (7.5%, N = 8) highlighted the need to perform scientific investigations that could facilitate the improvement of our current state of knowledge of the behavior of killer whales. Finally, 3 articles indicated solutions that were related to the economic field, specifically with regard to the contracting of insurance to cover the risks paced by the boats, and a single news item referred to improvements in the habitat of the killer whales that should be considered as a possible solution to these challenges. A summary of the relative frequencies of the categories associated with the variable Actions is available in the Supplementary Materials (see Table S4 in File S4). 3.2.4. Variable 4: Threats Towards the Iberian Killer Whale A total of 23.4% of the news under analysis in this context (N = 25) referred to at least one threat to Iberian killer whales. In the news as a whole, 6.5% of the articles under examination (N = 7) mentioned a single threat, whereas 16.8% of these news items (N = 18) alluded to 2 or more threats faced by orcas in the text. Regarding the types of threats to orcas that were mentioned in the articles, 18.7% of the news items (N = 20) addressed problems related to alterations of the habitats of these mammals, including by highlighting factors such as pollution and the accumulation of waste, marine overexploitation or the effects of climate change. In addition, the maritime traffic in the routes frequented by these killer whales, the resulting collisions with boats or the noise pollution generated by naval activity were mentioned by similar numbers of news items (16.8%, N = 18). Finally, other types of additions, such as attacks on killer whales, including by shooting, or the low reproduction rate observed in this species, were mentioned by fewer articles (11.2%, N = 12). A summary of the relative frequencies of the categories associated with the variable Threats is available in the Supplementary Materials (see Table S5 in File S4). 3.2.5. Variable 5: Legal Status of the Iberian Killer Whale A total of 26.2% of the news items under analysis in this context (N = 28) included information regarding at least one of the categories that pertained to the protection status of Iberian killer whales.
