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.

Where You Will See It In Cozumel
Rubble and coral bases at Tormentos, Yucab and Paradise Reef. Almost always spotted by a guide, rarely by a diver.
Reliable sites: Tormentos, Yucab, Paradise Reef.
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.
