This is a species of fish known as a Gurnard or Sea Robin.  They can be identified by their “wings” or large pectoral fins which resemble wings.  There are many species of Gurnards which inhabit the ocean floors in both tropical and temperate seas and so I have not yet been able to identify yet just what this species is.  This was caught which bottom fishing.  Note the large horns on the fish.  These apparently contain a venom that can cause severe pain.  It is best to be careful when handling one of these fish.
