Coelacanth - the living dinosaur known as old four legs - the Awesome World of Things
The coelacanth is a “living fossil”, because its fossils were found
long before the actual discovery of a live specimen. The coelacanth is
thought to have first evolved approximately 400 million years ago. The fish has a foul taste and is inedible. The natural habitat of the
fish is 120m below the surface of the ocean and has resulted in the
death of numerous divers who have attempted to film it. The fish is
associated with Dr JLB Smith who identified and confirmed the catch by
fisherman Captain Hendrick Goosen and discovery by museum curator
Marjorie Courtenay-Latimer.
