Description

The Whale Shark (Rhincodon typus) is the largest shark and fish in the ocean and one of the most recognisable. These gentle creatures are known for their massive size and kind nature. They cruise through at a relatively slow speed of 3mph (5kmph). Fully grown adults can grow up to 12m long and beyond. Despite their massive size, these giants filter feed on plankton, krill, and small fish.They can be found in all tropical oceans globally, swimming in shallow water and diving to depths.

Threats

IUCN Conservation Status: Endangered

Poaching

Unfortunately, illegal poaching can occur for meat, fins, and oils.

Vessel Strike

These creatures are vulnerable to vessel strikes due to feeding at the ocean surface. They can be hit by passing boats and ships, especially if feeding in shipping lanes.

Overfishing

These animals are threatened by illegal fishing practices, bycatch in fishing gear, overfishing of reef fish, and entanglement in fishing nets.

Habitation Loss

The loss of coral reefs and small fish in the reef ecosystem has a knock-on effect, leaving less available prey.
