Emma Murphy, a zoology curator at the National Museum of Ireland, expressed astonishment upon learning that a deceased Greenland shark had washed up on the shores of northwestern Ireland. These massive and ancient ocean creatures are typically elusive and inhabit the remote depths of the Arctic and North Atlantic oceans. This occurrence marks the first recorded stranding of this exceedingly rare species on Ireland’s coast.
The shark was first spotted near the town of Sligo on April 11 by a bystander who initially mistook it for a dead basking shark, a common species in Irish waters. Upon identification by scientists at the Irish Whale and Dolphin Group, colleagues at the National Museum of Ireland were alerted. The Greenland shark, known as one of the largest carnivorous shark species globally, can reach lengths of up to seven meters and boasts a remarkable lifespan of over 270 years, with the oldest recorded specimen estimated to be 400 years old.
Despite their primary habitat being the cold waters of the Arctic and North Atlantic, including regions like Quebec and Atlantic Canada, shark scientist Dean Grubbs suggests that Ireland falls within the known range for Greenland sharks due to their adaptability to cold temperatures. These sharks, which typically dwell at depths of around 2,000 meters, have been sporadically observed in diverse locations such as Belize and the Gulf of Mexico, indicating a wider habitat range than previously believed.
Given their deep-sea habitat, Greenland sharks are seldom encountered by humans. The rarity of sighting these creatures makes each encounter a significant event for researchers and enthusiasts. The recent retrieval of a stranded Greenland shark off the coast of Ireland offered scientists a unique opportunity to study the animal up close. The three-meter-long male shark, estimated to be approximately 150 years old, displayed no obvious signs of illness or injury, leaving researchers puzzled about the cause of its demise.
Efforts are underway to preserve the shark’s skin and skull for future display at the National Museum of Ireland, ensuring that this remarkable specimen will be available for public viewing for generations to come.
