Real-world information
The coelacanth is an ancient order of fish that was, for a long time, believed to be extinct, due to their disappearance from the fossil record 66 million years ago. The first ever live one was caught in 1938. It can grow up to two meters in length and lives for an average of forty-eight years. Coelacanths are found off the south coast of Africa, living in steep rocky shores, sheltering in caves during the day. It can travel around eight kilometers a night in search for food, passively swimming with the current, making it a "slow-moving" fish that only uses its fins to adjust its position. It preys on fish and squid, but some have been known to eat eels, skates, and even sharks. Its main predator is likely to be large sharks.

Trivia

 * In, if the player gives a Coelacanth to Wendell, he refuses to take it, saying his mother told him to not eat them. This could be due to their rarity, or due to the fact that they are inedible fish in the real world.
