“…There have been less than a hundred reports of sperm whale strandings in this region in the last 50 years. Moreover, in the last 25 years, around 50 sperm whales (from a total report These strandings are particularly significant due to the increasing social awareness and concern around the link of these deaths with anthropogenic activities (3,4). Geographically, the Canary Islands region holds history in the presence of many cetacean strandings related to anthropogenic activities, such as the proven cause-effect of the use of Mid Frequency Active Sonar (MFAS) by military operations with the mass stranding of beaked whales in the early 2000s, that lead to the implementation of an antisubmarine sonar ban around the archipelago since 2004 (5)(6)(7).…”

On the 21st of May 2023, a dead adult male sperm whale (Physeter macrocephalus) of 13 m in length and estimated weight of around 18,000 kg was reportedly stranded at Playa Los Nogales, La Palma, Canary Islands, Spain. A necropsy was performed 48hpm. A 50 cm diameter and 9.5 kg coprolite was found obstructing the caudal colon-rectal lumen. Necro-hemorrhagic lesions were found in heart muscles and three different bacteria of intestinal origin were isolated and identified (Edwarsiella tarda, Hathewaya limosa and Clostridium perfringens). It is reported a lethal septicemia of intestinal origin associated with ambergris coprolite as cause of death in this sperm whale.

“…Even in regions where management policies and procedures are in place, protocols may lack the detail required to undertake decision‐making (Boys et al, 2022d). This can lead to inappropriate intervention and unrealistic expectations from responders, particularly during discussions about emotive topics such as euthanasia (Boys et al, 2022d; Gales et al, 2008; Stockin et al, 2022). Delays to euthanasia and/or undertaking inappropriate interventions can prolong suffering of debilitated and/or moribund animals and cause further welfare compromise (Brownlow et al, 2015; Geraci & Lounsbury 2005; Perrin & Geraci 2008; Sharp et al, 2014).…”

Empirical assessment of cetacean welfare to inform stranding interventions is lacking. Here, potential welfare indicators are described for two stranded pygmy killer whales (Feresa attenuata), along with euthanasia procedures and pathology of potential relevance. The animals were filmed for 3.5 and 1.5 hr, respectively, allowing assessment of 19 indicators, including animal behaviors and human interventions. Eight interventions and 19 animal behaviors were identified; 17 and 11 behaviors were displayed by animal 1 and 2, respectively. Examination of ballistics euthanasia revealed atypical projectile placement and characterized animal behavioral responses, but welfare implications could not be assessed as insensibility was not verified in‐field. Pulmonary edema and renal degeneration were documented in both animals; differential etiologies include ischemia–reperfusion, shock, and/or myopathy. Potential relationships among histopathology and welfare indicators are explored to infer affective experiences. For example, simultaneous head‐lifting with respiration increased over time which, alongside pulmonary edema, suggests these animals experienced breathlessness. Other likely affective states include fatigue and discomfort; there are insufficient data to estimate the intensity or duration of these experiences or to provide an overall welfare grade/score. Further data are required to validate the proposed welfare indicators and to progress development of holistic approaches to welfare assessment at cetacean strandings.

“…There is increasing recognition that animal welfare science must be integrated alongside conservation biology to achieve wildlife management goals [1][2][3][4]. While conservation efforts involving human intervention often claim to consider animal welfare, robust welfare assessments are rarely undertaken [5][6][7][8][9]. This is probably due to limited data and protocols for assessing the welfare of wild species [10], and the need to apply practical and non-invasive indicators [11,12].…”

Management of live cetacean strandings generally focuses on refloating animals, yet there is a lack of scientific data to inform decision-making. Valid indicators that are practical to measure are needed to assess welfare status and survival likelihood for stranded cetaceans. The Delphi method was applied to gather international and interdisciplinary expert opinion to provide face validity to potential indicators of stranded cetacean welfare and survival likelihood. Two online questionnaires were conducted. In the first questionnaire these experts identified potential indicators of stranded cetacean welfare and survival likelihood. These indicators were subsequently scored by the same experts in questionnaire two, based on their value for assessing welfare/survival likelihood and being practical to measure. Indicators considered valuable and practical for assessing welfare and survival likelihood at strandings included animal-based indices of body and skin condition, signs of physical trauma, respiration rate and various behaviours. Resource-/management-based indicators related mainly to human intervention and should be correlated with animal-based indices to provide relevant evaluations. Importantly, inextricable links between welfare and survival for stranded cetaceans are emphasized, with 90% of indicators being similar for both. Investigations into these indicators should be conducted to develop a practical, science-based assessment framework to inform decision-making during stranding events.
