“Rebel” Coelacanth Stalked Ancient Seas


A new species of killer coelacanth that stalked Triassic seas has been identified from museum fossils, researchers say.

The coelacanth (pronounced SEE-la-kanth) is a type of primitive, slow-moving fish that was thought extinct until its rediscovery in 1938. The modern fish is sometimes called a living fossil, because it apparently existed largely unchanged for 320 million years.

But the newfound animal, dubbed Rebellatrix, is bizarre compared with previously known coelacanths, living or extinct, said study leader Andrew Wendruff, a biologist at the University of Alberta in Canada.

That’s because all other known coelacanth species have broad tails designed to lunge short distances after prey, Wendruff said.
