” An Ancient Fish Surprises Scientists with Slow Growth, Long Life”.
Ancient fish, named Coelacanth, a large bony fish with a three lobed tail and fleshy pectoral fins, the first appeared 400 million years ago. It was believed that Coelacanth had gone until a living Coelacanth was found off South Africa in 1938.A recent study found that the ancient fish can live 100 years, meaning earlier estimates were off by a factor of five.
To find the age of Coelacanth, sold for food, the scientists researchers decided to look at the scales under a special, polarized light and then they realized that for every large line there were five smaller lines and the smaller lines matched up better to one year of the fish’s growth. The female coelacanth carries babies for at least five years before giving birth. The female fish are not able to have babies until they are over fifty years old.
