Have you ever heard of a Coelacanth? They were thought to be extinct - the oldest fossils of these fish date back 410 million years! But, imagine how surprised fishermen were when a live Coelacanth was discovered off the coast of South Africa in 1938! From time to time they are found, but not often as they live in deep waters. Aside from still being alive, two more surprising things about Coelacanths are they typically live 100 years and mom Coelacanths are pregnant for five years! Yes, five years! I'm SO glad I'm not a Coelacanth.
