Tailspot Blenny

Ecsenius stigmatura

The Tailspot Blenny is a small, coppery-colored fish found in the Western Pacific, particularly around the Philippines and Indonesia. It is easily recognized by a distinct blackish spot at the base of its tail, which sets it apart from similar species. The blenny's body color can vary from grey to brown-orange, with a grey-blue head. Its eye is highlighted by a yellow iris and a yellow line running from below the eye to above the pectoral fin. When threatened, colors below its eye can turn bright pink. Tailspot Blennies inhabit coastal lagoons and sheltered coral reefs at depths ranging from 2 to 30 meters. They are often seen alone or in small groups, making them a solitary or semi-social species. As oviparous fish, they lay adhesive eggs that are attached to substrates via a filamentous pad. The larvae are planktonic and typically found in shallow coastal waters. Divers encountering the Tailspot Blenny can expect to see it perched on coral or rock surfaces, observing its surroundings. It is harmless to humans and is sometimes found in the aquarium trade. The species is currently listed as Least Concern by the IUCN.
