Researchers keep making surprising discoveries about the ancient fish called the coelacanth. Scientists believe the fish first appeared 400 million years ago. But they thought it had disappeared completely until a living coelacanth was found off South Africa in 1938. Then, experts thought for many years that the fish only lived to be about 20 years old. That would make the coelacanth one of the fastest-growing fish in the ocean. But a recent study found that the ancient fish can live 100 years, meaning earlier estimates were off by a factor of five. The study was published in the journal Current Biology.
