Eastern Pacific: San Diego Bay, California, USA (Ref. 2850) to Peru.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 2850)
Facultative air-breathing (Ref. 126274); Inhabits shallow sand or mud bottoms of bays and estuaries. An intertidal species that actively shuttles back and forth between rock pools and air (Ref. 31184). 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 (Ref. 92840). Breathes air when out of water (Ref. 31184).
