Were mermaids fiction or non-fiction?

Answer:
Mermaids are a fiction topic. They were first introduced when Greek fishermen caught sight of dugongs, but mistook them for young maidens with the top half being human features, but the bottom half was the tail of a fish. They later became known as mermaids, which means half-woman half-fish.
