Mermaids are legendary, aquatic creatures with the head, arms and torso of a human female and the tail of a fish. The male version of a mermaid is called a merman; gender-neutral plurals could be merpeople or merfolk. Various cultures throughout the world have similar figures. Because mermaids thrive in salt-water conditions, they would rarely be found in a freshwater lake or stream.
