Unveiling the Deep: UM scientists investigate Rare Sperm Whale Stranding

On the morning of March 9, 2026, the Environment and Resources Authority (ERA) alerted Professor Adriana Vella to a somber discovery: a young, deceased sperm whale (Physeter macrocephalus) had been located in Maltese waters. As the lead researcher of the Conservation Biology Research Group (CBRG) at the University of Malta, Professor Vella was immediately activated as part of the established national protocol for stranded cetaceans in Malta.

A Specialised Scientific Mission

The logistical challenge of reaching the carcass was met with the professional support of the Armed Forces of Malta (AFM). On 12 March, the AFM provided essential maritime transport, allowing Professor Vella to conduct a rigorous on-site examination.

The primary goal was to collect vital biological samples and morphological data before the carcass reached a state of advanced decomposition or was disposed of. For a species that spends much of its life in the abyssal depths, every stranding provides a rare, high-value window into the health, genetics, and diet of the Mediterranean sperm whale population—a group currently listed as Endangered on the IUCN Red List.

30 Years of Conservation Vigilance

This investigation is the latest chapter in a long-term scientific effort led by Professor Vella and the CBRG, which has been monitoring Maltese cetaceans since 1996. The group’s work focuses on moving beyond anecdotal sightings toward high-level, publishable data that informs national and international conservation policy.

Professor Vella’s expertise is well-documented; she previously led the investigation into the 2011 stranding of a Cuvier’s beaked whale in Qawra. Beyond the field, she serves as the National Contact Person for the European Cetacean Society and chaired the first-ever international conference on cetacean science held in Malta in 2015.

Collaborative Science: The "Notice to Mariners"

The success of such conservation research relies heavily on synergy between academic and maritime authorities. Transport Malta (formerly the Maritime Transport Authority) continues to play a pivotal role by issuing an annual Notice to Mariners. This notice encourages all persons at sea to report sightings, effectively turning the local maritime community into a vast network of "citizen scientists" contributing to long-term population data.

"Every specimen tells a story of the pressures our oceans face," the CBRG noted. "From plastic ingestion to acoustic pollution, these necropsies are essential for understanding how to better protect the giants that still roam the Mediterranean."
