More Info


Distribution

Ningaloo Reef, Rowley Shoals, Western Australia, and Ashmore Reef, Timor Sea, to Montague Island, southenr New South Wales; also Christmas Island, Indian Ocean and the Lord Howe Island region. The species occurs elsewhere in the tropical, Indo-west-central Pacific. 
Usually solitary on sandy and rubble substrates.

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

Carnivore - 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 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 has a short triangular flap on the anterior nostril (vs a long and slender flap of 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.
