📖 Overview

Most commonly found in sand and mud, near coastal reefs at depths of 1 up to at least 10 m. Burrows into the sand tail-first until only its eyes and the top of its snout are visible. Sometimes seen with only its head or snout protruding from the sand. More commonly encountered at night but also seen with its head protruding out of the substrate during the day. Observed with cleaner shrimp Periclimenes magnificus on its head. The shrimp would swim off for short periods and then return to this species . Feeds on small fishes and crustaceans .
