Lined Combtooth Blenny

Overview

The Lined Combtooth Blenny (Ecsenius lineatus) is a small, inquisitive marine fish widely distributed across the tropical Indo-West Pacific. Often found perched on coral or rock, these blennies are easily recognized by their distinct body markings and characteristic whisker-like appendages.

Distribution & habitat

This species inhabits clear, shallow coastal waters and outer reef crests where coral growth is abundant. While they are frequently observed in very shallow water, particularly in the northern parts of their range, they can be found at depths ranging from 1 to 28 meters.

Appearance

These blennies have an elongated, cylindrical body typically featuring a prominent dark longitudinal stripe that runs from the eye toward the tail. In many individuals, this stripe appears broken into a series of rectangular blotches. They are further distinguished by a pair of long, straight cirri (whisker-like appendages) located between their eyes. Their coloration often includes a lighter underside and pale, horizontal lines along the dorsal half of the body.

Biology & behavior

Lined Combtooth Blennies are generally solitary, though they may be seen in small groups or as distinct mated pairs. They are territorial fish that spend much of their time resting on the substrate, using their specialized comb-like teeth to graze on algae. They are oviparous, laying demersal, adhesive eggs that are attached to the reef surface by a small, filamentous pad. After hatching, the larvae lead a planktonic existence in shallow coastal waters.
