Bighead Gurnard Perch

Identification

The Bighead Gurnard Perch has a relatively large, rounded head and slender body.

Colouration is variable from whitish to greenish, blueish or brown. Pigmentation pattern on the caudal fin changes with growth. Young individuals have a vertical black band basally and another distally on the caudal fin. Older fish have small black spots scattered on the fin. The Bighead Gurnard Perch is the only species of Neosebastes that shows this distinct change (black bands to black spots) in the caudal fin colour pattern, although the caudal fin colour pattern of N. thetidis also changes with growth (two narrow bands changes to one broad band).

The Bighead Gurnard Perch can be distinguished from other members of the genus by having the following combination of characters: the underside of the mandible has three distinct pores on each side, the lower opercular spine has a spine arising half way along its length, and the third dorsal fin spine is the longest.
