Which fish is the largest in the ocean?
Quick Answer
The whale shark is the largest fish in the ocean. It can grow to about 12 metres or more, with some reports of individuals approaching 18 metres.
The Full Story
The whale shark is the largest fish species alive today. It is a filter feeder that swims slowly through warm tropical and subtropical oceans, eating plankton, small fish, and other tiny organisms. Adults commonly reach around 12 metres, and exceptionally large individuals may be longer. Even though it is a shark, it is harmless to people and feeds by filtering water through its mouth. Its size makes it one of the ocean’s most iconic giants.
