Longfinned triplefin

📖 Overview

Adults are commonly found in sheltered areas shallower than 5 m. Typical in shallow habitats in coastal mainland areas and seldom on offshore islands. Mainly found under rocks. They feed on a range of benthic invertebrates including ophiuroids, archaeogastropods, trichoptera and errant polychaetes . Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites . Larvae are planktonic which occur primarily in shallow, nearshore waters . They are caught by slurp guns and handnets .
