A carcass of a rare Arctic species, known as the "unicorn of the sea", has washed ashore in Ireland, marking the first time it has been seen in the country. The animal has been identified as a narwhal, with some outlets reporting that it was found on a beach in Donegal. It is unclear if the narwhal was alive when it was last seen, as one report mentions a carcass, while another mentions a whale off the US coast, suggesting it may have been spotted alive elsewhere.
