The Trigger Fish gets it's name from the small fin on the top of its head.
The Trigger Fish can lock this fin into place with a "trigger" which then has to be released before the fin can be lowered. This means that the Trigger Fish can wedge itself into holes and prevent itself from being removed by predators.
These fish mainly feed on crabs and shellfish and can grow up to 60cm. You're most likely to find them among reefs in the East Atlantic and Mediterranean.
Things to Do
- Watch out for his "Trigger" in action
- The females like to dig a hole and hide their eggs at the bottom of the sea, can you spot any here?
