The damselfish forms huge clouds of hundreds of individuals above rocky drop-offs, feeding on plankton in open water. At the first sign of danger, the entire school vanishes instantly into cracks in the rock.
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.
