Scorpaeniformes is an order of ray-finned fish, but it has also been called the Scleroparei. Species in this order have recently been reclassified into the Perciformes.

They are known as "mail-cheeked" fishes due to their distinguishing characteristic, the suborbital stay: a backwards extension of the third circumorbital bone (part of the lateral head/cheek skeleton, below the eye socket) across the cheek to the preoperculum, to which it is connected in most species.

[edit] Classification

The division of Scorpaeniformes into families is not settled; accounts range from 26 families[1][2] to 35 families[3][4].
