More Info


Distribution

Ningaloo Reef, Rowley Shoals, Western Australia, and Ashmore Reef, Timor Sea, to at least Sydney, with juveniles south to Montague Island, New South Wales; also Christmas Island in the eastern Indian Ocean, the Lord Howe Island region and Norfolk Island in the Tasman Sea. Elsewhere the species occurs in the tropical, Indo-west-central Pacific. 
Usually solitary on sandy and rubble substrates near reefs.

Features

Dorsal fin 11-13; Anal fin 8-10; Pectoral fin 11-13; Pelvic fin 8; Lateral line scales 59-62; scale rows above lateral line 5.5.
Cheek usually not scaled to preopercular margin; membranous flap on anterior nostrils long and slender; pectoral fins not reaching a line connecting origins of dorsal and pelvic fins.

Feeding

Feeds on small fishes and shrimps.

Biology

Up to four males have been observed courting a single larger female. A courting male may station itself atop a female, and puff out its gill cover and spread its fins in a display of aggression towards other males.

Similar Species

Often misidentified as the Variegated Lizardfish, Synodus variegatus, which has the cheek fully scaled behind the mouth to the edge of the preopercle (vs cheek usually not scaled to preopercular margin), and also has a short triangular flap on the anterior nostril (vs a long and slender flap in S. dermatogenys).
Differs from the similar Streaky Lizardfish, Synodus similis (which also a blue stripe along the side) in lacking a black spots or a black blotch on the upper rear part of the gill cover.

Etymology

The specific name dermatogenys is from the Greek dermatos (= skin) and genys (= cheek) in reference to the lower cheek being naked.
