Ecsenius isos

Ecsenius isos is a species of combtooth blenny in the genus Ecsenius.[1] It is found in coral reefs in the western central Pacific ocean, around New Hebrides and New Caledonia.[1] It was named by Victor Gruschka Springer and James F. McKinney in 1976, and can reach a maximum length of 3.2 centimetres.[1] Blennies in this species primarily feed off of plants, including benthic algae and weeds.[2] The specific name isos refers to the dark spots beneath the blennies' heads.[3]
