Animal Species:Lance Blenny, Aspidontus dussumieri (Valenciennes, 1836)
Despite having a large fang on either side of the lower jaw the Lance Blenny seems to eat primarily algae and detritus.
Slender Sabretooth Blenny
The Lance Blenny is white with a dark stripe from the eye to the caudal fin. It has an elongate body with a long-based dorsal fin. The mouth is positioned ventrally below the rounded snout. There is a large fang on either side of the lower jaw.
The Lance Blenny looks similar to the False Cleanerfish but can be distinguished by snout shape and the colour of the stripe on the head behind the eye. The Lance Blenny has a rounded snout with a plain brown stripe behind the eye. False Cleanerfish have a pointed snout and a bluish stripe usually with dark margins.
The species grows to 12 cm in length.
It occurs in throughout the Indo-Pacific. In Australia it is known from the central to north-western coasts of Western Australia and from the northern coast of Queensland to central New South Wales.
