What defines this group — Reef fish
The bony fish that live against coral and rock: the living backdrop of almost every dive.
- A bony skeleton, scales, and a rigid gill cover closing over the gills.
- A swim bladder acts as a float: they hold their depth without swimming.
- Many change colour, pattern — sometimes even sex — over the course of their life.
