Largest Fish in the World

20 fish · 560–1,800 cm

The ocean and freshwater systems harbor fish of staggering proportions. From the gentle whale shark cruising tropical seas to the massive ocean sunfish drifting in open water, the largest fish species have evolved body plans that maximize size for filter feeding, predation, or thermal regulation.

Body length in fish is measured as total length (TL) — from the tip of the snout to the end of the caudal fin. For species with forked tails, fork length (FL) is sometimes used instead. Maximum recorded lengths come from scientific surveys, museum specimens, and verified angler catches published in ichthyological literature.

Cartilaginous fish (sharks and rays) dominate the upper ranks, but bony fish like the oarfish and ocean sunfish also reach extraordinary sizes. Understanding maximum size helps fisheries biologists set harvest limits and conservation priorities.

Frequently Asked Questions

What is the largest fish in the world?
The whale shark (Rhincodon typus) is the largest living fish, reaching verified lengths of over 12 meters (40 feet). Despite their enormous size, whale sharks are filter feeders that consume plankton and small fish.
How do scientists measure fish length?
Fish length is measured as total length (TL) — from the tip of the snout to the end of the caudal fin. For species with forked tails, fork length (FL) from snout to the fork of the tail is sometimes used instead.
Are the largest fish dangerous to humans?
Most of the world's largest fish are harmless to humans. Whale sharks and basking sharks are gentle filter feeders, and ocean sunfish are slow-moving plankton eaters. The great white shark is the notable exception among the largest species.
