Identification

The Salamanderfish is an elongate species with a cylindrical body and reddish eyes. It is greenish-brown above and pale below. It has dark blotches and silver speckles on the sides of the body.

The Salamanderfish is the only species in the family Lepidogalaxiidae.

Habitat

The species is found in pools in sandy peat flat areas. These waters are usually darkly tannin stained and often very acidic (pH 3.0-6.5). When pools start to dry up in summer, the fish constructs a small burrow in which it aestivates until heavy rains fall in winter.

Distribution

It is endemic to Australia, occurring in a restricted area of Western Australia between the Albany District and Scott River.

Other behaviours and adaptations

The Salamanderfish cannot move its eyes. Instead it has an unusually flexible neck, that allows the head to be moved independently of the body.
