What it is

The fur-bearing trout is a legendary aquatic creature featured in the folk traditions of Iceland and North America. It is described as a fish that has developed a dense coat of fur. This adaptation is said to help the animal retain body heat in extremely cold environments. The creature belongs to the category of fantastic beasts and urban legends. It is not a real biological species but a product of storytelling and practical jokes.

Where it comes from

Tales about hairy fish date back to the seventeenth century. A Scottish immigrant wrote to relatives about "furried animals and fish" in the New World. In Iceland, the Loðsilungur is linked to demons and giants. American publications began featuring the story in the twentieth century. J.H. Hicken wrote about it in a 1929 Montana Wildlife article. Robert Benchley also included a version in his 1936 book. Wilbur Foshay promoted a local version in Colorado.

How it is done

Stories describe how the fish acquires its coat. One theory suggests the cold water causes the fur to grow. Another claims hair tonic was spilled into rivers, causing the growth. Fishermen are sometimes depicted acting as barbers to lure the fish. They offer free trims to attract the creatures from the water. Some accounts say the fur falls off when the fish is removed from the cold water.

Tools and materials

Taxidermy specimens have been created to support these stories. Ross C. Jobe made a famous example using white rabbit fur. He attached the fur to a trout body. This specimen was sent to the Royal Museum of Scotland. The hoax was discovered when the purchaser learned the truth. Other descriptions mention reddish hair on the lower jaw and fins.
