Description

The whale shark is the largest fish in the world; it can reach a length of over 12 metres and possibly up to about 18-20 metres. It has a bulky, grey-blue body with a striking pattern of light spots and stripes and an enormous, broad mouth at the front of the head. Despite its size it is completely harmless to humans: it is a filter feeder that sifts large volumes of water with its widely gaping mouth and so extracts plankton, small crustaceans, fish eggs and small fishes. It lives oceanically but also comes close inshore, sometimes into lagoons and atolls. Owing to fishing and bycatch the species is regarded as endangered.
