What to look for

How to Recognize It

A deep, angular body with strong teeth and a locking first dorsal spine that gives the family its name.

How It Behaves

Confident and territorial, especially around a nest, it may warn intruders with direct approaches and raised fins.

Special Ability

The dorsal trigger locks the fish into reef cracks, making it difficult for a predator to pull free.

Dive responsibly

Share the water well

How to Approach

If a nesting triggerfish approaches, swim horizontally away from the territory rather than directly upward.

Safety

Large nesting triggerfish can bite. Watch posture, respect warnings and leave the territory promptly.
