The Gill-man, better known as The Creature from the Black Lagoon, was an aquatic reptilian man-like creature and the titular villainous character from the 1954 film, "Creature from the Black Lagoon". In the film, it is the last of its kind and lives in the amazon rainforest. Its amphibious look has inspired many of the sea beast films.
When a human expedition arrives, the creature kills several of the expedition members and even tries to abduct Kay, the only female of the group. However in the end, it is shot dead by the remaining expedition members and its body sinks into the murky dark water.
