| "'Feejee Mermaid' has become the generic term for the many fake mermaids that can be found around the world..."
This article contains information relating to a hoax. According to Cambridge dictionary a hoax is "a plan to deceive a large group of people; a trick."
According to legend, the fur-bearing trout was first encountered by Europeans when Scottish settlers emigrated to Canada during the seventeenth century. One settler wrote home remarking about the abundance of "furried animals and fish" in the new land. Asked to provide more information about the furried fish, he duly sent home a specimen. Fur-Bearing trouts mounted as trophies can be found hanging on walls throughout the Great Lakes region of North America.
The legend probably started by people seeing trout infected with saprolegnia, which makes the fish seem to have tufts of fur.
