Spotted Scorpionfish in Cozumel
Spotted Scorpionfish (Scorpaena plumieri) in Cozumel: how to identify it, where it is reliably seen, and what it is commonly confused with.
A lumpy, mottled fish that looks exactly like the rock it is sitting on, with feathery skin flaps over the eyes. The giveaway is the flash of black-and-white banding on the inner pectoral fins when it moves.

Behaviour
An ambush predator that will not move until something is almost touching it — which is what makes it a hazard. It relies entirely on not being seen.
Commonly Confused With
- Lionfish — The lionfish is boldly striped with long open fins; the scorpionfish is flattened, mottled and pressed to the substrate.
- Frogfish — Frogfish have a rounder body and a fishing lure on the forehead.
Diving Etiquette And Safety
Venomous dorsal spines. This is the single strongest argument for perfect buoyancy and for never putting a hand down on the reef to steady yourself.
