Sperm Whale Stranding in Oman Highlights Importance of Regional Collaboration

On December 10th, a sperm whale stranded and died off the coast of Al-Sawadi Beach in Oman, presenting an opportunity for scientists to collect crucial samples to support marine research and conservation efforts. The event underscores the importance of regional collaboration in responding to marine mammal strandings and advancing scientific understanding of the ocean environment.

The stranding was swiftly reported to Oman’s whale stranding network, enabling an organized and collaborative response. The Environment Authority in Oman  organised the stranding response including a necropsy, with expert technical assistance from veterinarians at Yas SeaWorld Research & Rescue Center, and valuable support from the Environment Society of Oman, Future Seas Global SPC, and Five Oceans Environmental Services.

The initial evaluation of the carcass did not yield any obvious signs of the cause of death, although in cases such as these determining the cause of death is not always obvious due to the complexity of conducting a full evaluation of such a large animal and the many different potential contributing factors to mortality.  Importantly, every stranding holds a treasure trove of information, and the data and samples collected will now be analyzed, which will hopefully provide insights into the age, reproductive status, and health of the whale,  as well as its  marine environment. This research will contribute to understanding the challenges faced by marine mammals in the region and support the development of more effective conservation strategies.

The successful management of the incident also involved key logistical support from the Royal Navy of Oman and the Royal Oman Police, who managed crowd control and oversaw the removal process. The Musannah Municipality facilitated the disposal of the carcass, while Sultan Qaboos University is storing the samples and will assist in their scientific analysis.

This effort highlights the value of regional collaboration to respond to stranding events – a topic discussed during the most recent ASWN annual virtual meeting held on October 31, 2024, and in earlier Stranding Working Group discussions. During these meetings, members emphasized the value of collective action, provision of technical support from veterinarians and pathologists trained in cetacean strandings,  and information sharing to enhance stranding response and investigation efforts. The insights gained from this stranding response will not only deepen our understanding of marine mammals but also strengthen conservation initiatives across the Arabian Sea region.
