Conservation overview

The whale shark is the largest living fish — a gentle filter-feeder that strains plankton and small fish from warm oceans. It is assessed as Endangered.

Despite its size it is harmless to people, and it gathers seasonally at predictable feeding sites in several parts of the world.

Range & habitat

The largest living fish, found in warm-temperate and tropical oceans worldwide.

Major threats

Threats below are drawn from the authoritative sources listed on this page. For the current, complete assessment, see the IUCN Red List.

  • Targeted and incidental fishing
  • Vessel strikes
  • Disturbance at aggregation sites

Why it matters

Whale sharks grow slowly and mature late, which makes their populations slow to rebuild and especially sensitive to fishing pressure and vessel strikes.
