📖 Overview

Adults are restricted to shallow waters and dwell among rocks and coral reefs , where there is considerable wave action . They bite very severely, with their two very long and sharp canine teeth . Are grazers feeding on filamentous algae and detritus. Larvae feed on plankton; during larval metamorphosis to adult stage, there is no feeding and rely on lipids stored in the liver . Oviparous. Eggs are demersal and adhesive , and are attached to the substrate via a filamentous, adhesive pad or pedestal . Ophioblennius larvae are frequently taken in deep water column . Adult males with fleshy rugosities on anal-fin spines that secrete antimicrobial mucus applied to eggs being guarded .
