Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	The Oyster Blenny is usually found in shallow estuarine waters, down to approximately 5 m (J. Williams pers. comm. 2009), and is associated with oyster shells or calcareous polychaete worm tubes, on tidal mudflats. Females deposit 200–500 eggs in batches on the inside of oyster shells (Francis et al. 2004). Like all Blenniidae, this species is gonochoristic and an oviparous nest spawner. The male guards the deposited eggs which are demersal and adhesive. After hatching, the larvae are planktonic before they settle on the bottom.
Systems:	Marine
