The discovery of a rare Greenland shark washed up on the shores of northwestern Ireland has left zoologist Emma Murphy and her team at the National Museum of Ireland in awe. The massive and ancient species, known for its elusiveness and preference for the Arctic and North Atlantic oceans, is a unique find in Irish waters. This marks the first known instance of a Greenland shark stranding on Ireland’s coast.
The shark, measuring approximately three meters and identified as a male nearing sexual maturity, was found near Sligo on April 11 by a bystander who initially mistook it for a basking shark, commonly seen in the region. Upon closer examination and photographic confirmation by scientists at the Irish Whale and Dolphin Group, it was determined to be a Greenland shark.
Greenland sharks are among the largest carnivorous shark species globally, second only to the great white, with an average length of three to five meters and a maximum recorded length of seven meters. Remarkably, they hold the title of the world’s longest-lived vertebrate, with a lifespan exceeding 270 years, as evidenced by a specimen estimated to have lived up to 400 years.
While these sharks typically inhabit cold waters such as those in the Arctic and North Atlantic, including regions like Quebec and Atlantic Canada, shark expert Dean Grubbs suggests that their range may be more extensive than commonly believed. Due to their mobility and adaptability to cold temperatures below 6°C, Greenland sharks could potentially be found in various locations, including unexpected ones like Belize and the Gulf of Mexico.
Despite their longevity and size, Greenland sharks are seldom encountered by humans due to their deep-sea habitats. The recent discovery in Ireland provided a rare opportunity for researchers to observe the majestic creature up close. The shark’s carcass was retrieved with care, and ongoing examinations aim to unravel the mystery of its demise, as it appeared healthy without any apparent injuries or ailments.
As the scientists await further test results, plans are underway to preserve the shark’s skin and skull for public display at the museum, ensuring that this remarkable specimen will be admired by future generations. The extraordinary find has not only expanded knowledge of the Greenland shark’s habitat range but also highlighted the importance of conserving and studying these enigmatic marine creatures.
