Orange-lined Triggerfish

Found singly and territorial, in lower surge zones, of deep lagoons and seaward reefs, rich in coral growth.
Females identified by spots over nose. Males plain over nose.

These triggerfish build a shallow nest in the sand with tow adults guarding the eggs, they become extremely aggressive to fish and divers alike.

Triggerfish have a hard spine dorsal fin that can be locked.
When sleeping this spine is used to wedge them into place in a crevasse and so deter predators from pulling them out of their bed!
The spine is also held erect as a warning to other fish to stay away.
Several large Titans blow shallow depressions in the sand for nesting and if approached will raise this spine as a warning, if ignored they may charge, even divers! especially the Titan Triggerfish who will take a tasty bite. Beware.
