How a Walrus Found Its Way to the Shores of Wales
Initial Discovery and Identification
On March 20, the RSPCA in Wales received an unusual call. For the first time in its 200-year history, they were asked to investigate an Atlantic walrus resting on the coast of Pembrokeshire. This juvenile walrus, approximately the size of a cow, quickly became a local celebrity, with residents suggesting names like Wally, Isabelle, and Cain.
Origin and Journey
Experts believe that this walrus likely originated from either Greenland or the Norwegian archipelago Svalbard. Photographs suggest that it swam from Ireland to Wales in about six days, covering a distance of approximately 250 miles. It is suspected to be the same walrus spotted in Denmark in mid-February.
Physical Characteristics and Health
The walrus has tusks under four inches long, a common feature among walruses. Biologists were unable to determine its gender based on its tusks alone. Despite being far from its home, the walrus appeared to be in relatively good health. RSPCA animal rescue officer Ellie West observed that it was resting and slightly underweight but showed no signs of sickness or injury.
Behavior and Habits
Walruses are known to rest on land or sea ice, which is becoming increasingly scarce due to climate change. The walrus in Wales rested for about two days before returning to sea on March 22. It typically swims at an average speed of about four miles per hour, aided by its thick layer of insulating blubber.
Conservation Concerns
The RSPCA and the Welsh Marine Life Rescue closely monitored the walrus during its stay in Pembrokeshire to ensure its well-being and prevent disturbance. Lucy Babey, who leads science and conservation at ORCA, emphasized the importance of maintaining a safe distance from the walrus. “This animal is going to be pretty exhausted from all of its swimming,” she said. “It is probably going to be stressed out as it is not in an environment it is used to.”
Historical Context and Previous Sightings
While this was the first time a walrus had been spotted on the coast of Pembrokeshire, it is not the first instance of walruses visiting Ireland and Wales. Since 1979, there have been eight confirmed sightings of walruses in Ireland and a few in Scotland. In 2018, a walrus was observed traveling around various islands in Scotland for several months.
Scientific Significance
The presence of a walrus in Wales highlights the interconnectedness of marine ecosystems and the potential for long-distance travel by these animals. It also raises questions about the impact of climate change on walrus populations and their ability to find suitable resting and feeding grounds.
Public Response and Safety Precautions
The Irish Whale and Dolphin Group shared photographs comparing the walrus spotted in Ireland to the one in Wales, suggesting they may be the same individual. The RSPCA has requested that the public not approach the walrus if it reappears and to maintain a safe distance for both the animal’s well-being and their own safety.
