Whale Shark

The whale shark (Rhincodon typus) is a slow-moving filter feeding shark and the largest known extant fish species. The largest confirmed individual had a length of 12.65 metres (41.50 ft) and a weight of more than 21.5 metric tons (47,000 lb), and there are unconfirmed reports of considerably larger whale sharks. Claims of individuals over 14 metres (46 ft) long and weighing at least 30 metric tons (66,000 lb) are not uncommon. The whale shark holds many records for sheer size in the animal kingdom, most notably being by far the largest living non-mammalian vertebrate, rivalling many of the largest dinosaurs in weight.
