A DIVING team located a school of coelacanths – an elusive prehistoric fish known as a “living fossil” – in Indian Ocean waters off eastern South Africa on Monday and is filming them, SABC radio reported. Coelacanths, a 400 million year-old species, were thought to have become extinct 70 or 80-million years ago until one was caught in 1938. Measuring at least a meter long as adults, the coelacanth is unlike other living fish in that its vertebral column is not fully developed. It also has paired fins that move in a way similar to human limbs. Dive team spokesman Mike Laws said the team would intensify their efforts on Tuesday but would concentrate on locating young fish to prove there is a viable coelacanth community off the northern KwaZulu-Natal coast near Sodwana Bay.
