Goatfish

The goatfishes are ray-finned fish of the family Mullidae, the only family in the suborder Mulloidei of the order Syngnathiformes. The family is also sometimes referred to as the red mullets, which also refers more narrowly to the genus Mullus. The family name and the English common name mullet derived from Latin mullus, the red mullet; other than the red mullet and the striped red mullet or surmullet, the English word "mullet" generally refers to a different family of fish, the Mugilidae or gray mullets.
