This blind goby is usually found under rocks in shallow water or surf; sandy areas among rocks in kelp beds, and holes in rocks. It occurs from intertidal areas to 15 m depth. Usually spends most of its life inside a burrow which it shares together with a pair of Thalianassa californiensis (Ref. 92840). Juveniles have rudimentary eyes to find a shrimp burrow. Adults probably never leave the burrow, resulting in the lowest oxygen consumption recorded in FishBase (ver. 05/2018). Monogamous (Ref. 52884). Oviparous (Ref. 205). Parents guard the eggs which are found attached to the walls of burrows (Ref. 56079). Also survives well in captivity.
