Coelacanth
Latimeria was first found by scientists in 1938 by Marjorie Courtenay Latimer, the curator of a small museum in the South African port town of East London. She was visiting a fisherman who would let her search through his boat's catch for interesting specimens. Another one was found off the Comoros islands in 1952. The largest specimen was about 1.8 metres (~6 ft).
