This species grows to a length of 6.4 centimetres (2.5 in) SL though most do not exceed 4.2 centimetres (1.7 in) TL. This fish can also be found displayed in public aquaria. This species is the only known member of its genus.
Behaviour 3
In contrast to most gobies, the Arrow Goby does not build a nest or care for its young. Eggs are distributed over a considerable area, with a spawning peak from March to June. The Arrow Goby uses burrows for shelter and can be collected at low tide by digging. (Eschmeyer et al. 1983).
Habitat 4
Habitat Type: Marine
Comments: Tidal mudflats, sheltered bays, estuaries, lagoons, tidal sloughs. Only occasionally enters low-salinity environments. Burrows into sand or mud at low tide, often sheltered with commensal shrimps or worms (Lee et al. 1980). Scatters eggs (Eschmeyer and Herald 1983).
Trophic strategy 5
Inhabits sand or mud bottom. Retreats into shrimp burrows when threatened and at low tide (Ref. 6885). Commonly in estuaries, lagoons and tidal sloughs. Reported to occur in freshwater. Adults feeds on diatoms, green algae, tintinnids, eggs and young of their hosts (Ref. 6885). Positions large food particles near crabs to be torn to smaller pieces (Ref. 6885). Preyed upon by Sebastes, staghorn sculpin, whitespot greenling, and terns (Ref. 6885).
