Split-ray pygmygoby

📖 Overview

Species collected from jetty pilings, log debris, and concrete stairs at the water’s edge, at about 1-4 meters. It apparently have an affinity for sponge-encrusted surfaces, but the general area where it is observed is characterized by extensive silty mud substrata inhabited by a large number of burrowing gobies. It was not previously observed despite nearly 100 hours of scuba-diving because the collection site is immediately adjacent to shore at a busy shipyard where diving is usually banned during daylight hours. Most of the specimens were found on the inner side of a single pillar of the jetty, which was situated in total shade .
