The each-uisge, a supernatural water horse found in the Scottish Highlands, has been described as "perhaps the fiercest and most dangerous of all the water-horses" by the folklorist Katharine Briggs.

However, the merest glimpse or smell of water means the beginning of the end for the rider, for the each-uisge's skin becomes adhesive and the creature immediately goes to the deepest part of the loch with its victim.

[1] In its human form it is said to appear as a handsome man, and can be recognised as a mythological creature only by the water weeds[2] or profuse sand and mud in its hair.

In the morning there was nothing left of the creature apart from a jelly-like substance.The Scottish folklorist John Gregorson Campbell recorded numerous tales and traditions concerning the each-uisge.

In their predatory hunger water horses may even turn on their own kind if the scent of a previous human rider is strong enough on the monster's body.

The An t-Each Ban was a white water-horse, which despite not being the usual black colour was otherwise "traditional", seeking out travellers on stormy nights in equine form, and leaping with its victims into deep pools.

When he stretched himself she discovered that he had horse's hooves and quietly made her escape (in variations of the tale she finds the presence of water weeds or sand in his hair).

It sometimes comes out of the water to gallop on land and, despite the danger, if the aughisky can be caught and tamed then it will make the finest of steeds provided it is not allowed to glimpse the ocean.
