Dobhar-chú
The Dobhar-chú, or King otter, is a creature of Irish and Scottish folklore. It resembles both a dog and an otter, though it sometimes is described as half dog, half fish. It lives in water and has fur with protective properties. There are little to no written records of the Dobhar-Chú since its legend has relied heavily on oral storytelling and tradition.
Etymology
Dobharchú is one of the two most common Irish words for 'otter'. The modern Irish word for 'water' is uisce, although dobhar is also used in placenames. Dobhar is a much older form and cognates are found in other Celtic languages. Cú is 'hound' in Irish. The Dobhar-chú is also known as the dobarcu, and anglicised as doyarchu, dhuragoo, dorraghow or anchu.Description
Physical description of the Dobhar-Chú resembles an otter but said to be about five times as large, with a white pelt, black ear tips, and a black cross shape on its back. Though, due to the murky waters it is said to reside in, its pelt may be portrayed as darker.Headstone
A headstone, found in Conwall cemetery in Glenade, County Leitrim, depicts the Dobhar-chú and is related to a tale of an attack on a local woman by the creature. The stone is claimed to be the headstone of a grave of a woman killed by the Dobhar-chú in the 18th century.The monument is a recumbent flag of sandstone, which is about in size. It depicts a recumbent animal having body and legs like those of a dog with the characteristic depth of rib and strength of thigh. The tail, long and curved, shows a definite tuft. The rear of the haunch, and still more the tail, are in exceptionally low relief, apparently due to the loss of a thin flake from the face of the slab. So far the description is canine. The lettering, and carving are in relief.
