The Javelin Pipefish is endemic to Australia. This variably coloured species grows to about 10 cm in length.
The Javelin Pipefish has an extremely elongate slender body that is encased in bony rings. The length of the body posterior to the dorsal fin is longer than that before the dorsal fin. The dorsal margin of the snout is concave.
Colouration of the species is variable. It is usually plain, but may have dark bars on the sides of the body. The anterior region of the dorsal fin often has a brown blotch. Females are brown, green, yellow or whitish. Males are usually white to blue with bright scarlet operculae.
The Javelin Pipefish is usually encountered in algal beds and rubbly substrates near rocky reefs.
The species is endemic to Australia, occurring in temperate inshore waters from northern New South Wales, around the south of the country to south-western Western Australia.
