Small transparent fishes with slender compressed bodies, a rounded head and an almost vertical mouth; pelvic fins minute, fused. Males and females are sexually dimorphic - males with large, flattened teeth, females with minute, conical teeth. Transparent with small scattered spots, and a series of tiny black spots along anal fin base to tail. To 3.5 cm, rarely longer than 2.5 cm.
Glassgobies often form large schools in estuaries and in the upper reaches of bays, often entering freshwater. They are rarely seen due to their small size and transparent bodies, and are often mistaken for larvae.
South-eastern and eastern Australia.
