Dobhar-chú

Also called Dobhar chu, Dobarcu, King otter, Water hound, Irish crocodile, Doyarchu, Dhuragoo

Ireland's giant 'king otter', remembered on an 18th-century gravestone.

The Dobhar-chú, Irish for 'water hound', is a giant otter-like creature of Irish lakes, said to be several times the size of a normal otter, with a white or dark pelt and black-tipped ears. It is fiercely territorial and is said to whistle to its mate.

Its best-known story comes from Glenade Lough in County Leitrim. In 1722 Grace Connolly went to the lake to wash clothes and was found dead with the creature lying on her. Her husband killed it, and its mate burst from the water and chased him until it too was killed. A gravestone in Conwall cemetery, said to be hers, is carved with an otter-like animal.

Sightings of large otter-like animals are still reported now and then in the lakes of the west of Ireland.
