1 species

The arrow goby (Clevelandia ios) is a species of goby native to marine and brackish waters of the Pacific coast of North America from British Columbia to Baja California. 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.

Arrow gobies are found along the Pacific Coast of North America, from the Rivers Inlet in British Columbia to Baja California.

The arrow goby occurs in sand or mud substrates, where it uses burrows created by invertebrates as shelters when it is threatened and as a refuge at low tide. Some of the species which make burrows used by arrow gobies include the shrimps Neotrypaea californiensis and Upogebia pugettensis and the fat innkeeper worm Urechis caupo. It is a common species of estuaries, lagoons and tidal sloughs, and it has been reported in freshwater. The adults feed on diatoms, green algae, tintinnids, and the eggs and young of the host shrimp or prawn. This species will place large food items close to crabs so that the crab will tear it into smaller pieces. Arrow gobies are prey for Sebastes, staghorn sculpin, whitespot greenling and terns. This species does not build a nest or provide any care for its offspring, and the eggs are dispersed into the water column. The underside of this goby is silvery, and when threatened, they use this to make a brief signal to other gobies before quickly taking refuge in the burrow. This is also used to signal for mates. The individuals of this species are protogynous hermaphrodites; young adults are females and as they mature they become male.
