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.

Classification

The division of Scorpaeniformes into families is not settled; accounts range from 26 families [cite book | author = Joseph S.

Long | publisher = California Academy of Sciences | year = 1998 | id = ISBN 0-940228-47-5] [FishBase order | order = Scorpaeniformes | month = February | year = 2006] .
