Did you know?
The giant grouper is the largest bony fish found on coral reefs, able to grow beyond 2.7 meters and 400 kg. A fairly bold predator, it will often approach divers closely, which unfortunately also makes it an easy target for fishing.
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.
