Blenny Yellowtail (fang)


This product is unavailable

Meiacanthus atrodorsalis                                                                               Summary:
A fangblenny with a greyish-blue head and anterior body that becomes pale yellow to whitish, a yellowish caudal fin, a black basal stripe along the dorsal-fin base and a diagonal blue-edged black band through the eye.

The Eyelash Fangblenny has large venomous canines in the lower jaw that are used for defense and aggressive interactions with other Eyelash Fangblennies, not for feeding. Potential predators quickly learn to avoid these small venomous fishes, allowing the blennies to forage out in open water. This species is mimicked by the Bicolor Fangblenny, Plagiotremus laudandus, and possibly by the Bicolor Combtooth Blenny, Ecsenius bicolor.
