Pho-a

In the folklore of the British Isles, the general designation of a number of spirits, most often evil and dangerous, closely related to water. They are described as noseless anthropomorphic creatures with a horse's mane, webbed fingers, or with a spiked tail. They can turn into stallions and go out on land in this form, looking for victims, sometimes they take human form and choose their wives among people. The offspring from such a marriage, as a rule, has some flaw — webbing between the fingers, tail or hypertrophied individual parts of the body or face, and also experiences fear of sunlight and cold steel.
