Did you know?
The Mediterranean rainbow wrasse changes appearance dramatically over its life: it starts as a striped brownish-orange female, and some individuals later transform into vivid blue-green males with an orange zigzag pattern. This sex change, called protogynous hermaphroditism, comes with a complete shift in territorial behavior.
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.
