Identification

The plumed scorpionfish is named for the long, fleshy projections above each eye. It is not often seen because of its extremely complex shape and the numerous skin coverings, spines and appendages that allow it to blend into its habitat so well that it almost becomes a clump of algae. The only thing that gives it away are its eyes.
