The potato grouper is known for its curiosity — rather than fleeing divers, it often approaches to check them out, a trait that has made it famous at certain dive sites but also more vulnerable to fishing. It can grow to more than 2 meters long.
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.
