A combtooth blenny with two dark lateral stripes, one immediately above the pectoral fin and one from the chin running below the eye through the pectoral-fin base, usually separated by a yellow stripe (sometimes a white stripe). The species is a white below and has a narrow dark stripe along the dorsal-fin base, a black submarginal band on the dorsal fin, and a yellow caudal fin.
The dark stripe running through the eye is separated from the margin of the upper lip by a broad pale area that is about equal to, or wider than the width of the dark stripe.

More Info


Endemic to eastern Australia, from the Torres Strait, Queensland, to at least Sydney, New South Wales.


The Lined Fangblenny has a pair of venomous canines in the lower jaw that they use for protection against predators and to protect their territory - not for feeding. This species is mimicked by the Yellow Sabretooth Blenny, Petroscirtes fallax, and juvenile Two-line Monocle Bream, Scolopsis bilineata.


The specific name is from the Latin lineatus (= lined), in reference to the  three dark stripes on head and body, separated by pale interspaces, all of approximately equal width
