📖 Overview

Facultative air-breathing ; Inhabits shallow sand or mud bottoms of bays and estuaries. An intertidal species that actively shuttles back and forth between rock pools and air . For food ingestion it leaves the home pool during low tides, takes a mouth full of mud and returns to its pool where it washes out the mud through its gill membrane and swallows particles which are sieved by the gill rakers . Breathes air when out of water .
