It is harmless to humans, living off plankton, invertebrates and other small organisms and rarely travelling faster than 5 kilometres per hour. It uses specially adapted gill arches to filter the water, removing anything edible. Its 1.5 metre diameter mouth can circulate up to 6000 litres of water an hour. It is a tropical fish and its upper age limit has been estimated at between 60 and 150 years. This shark was photographed in the Indian Ocean.
