It took me ages to learn how to spell coelacanth (I say it loudly in my head every time I type).
When scientists were puzzling out the evolution of land walking animals from an aquatic ancestor the coelacanth was thought to be one of the links. It had strong lobed fins which may be a fore-runner to limbs, well at least according to the fossil record because the coelacanth seemed to be just a memory in stone, extinct with the dinosaurs 65 million years ago.
Until 1938 when fisherman off South Africa caught one in their nets! It has been nick named a living fossil but these fish are extremely are so let’s hope the stay living and less fossil.
