Summary:
A small yellow to whitish sabretooth blenny with three black stripes on the body, the lowermost stripe extending well onto the pectoral-fin base, but not onto the anal-fin base, a black spot on the outer margin of the anterior dorsal fin, and clear anal and caudal fins.
The Yellow Sabretooth Blenny may mimic the Line Fangblenny, Meiacanthus lineatus, which has a pair of venomous canines in the lower jaw.
