Whiskered Prowfish, Neopataecus waterhousii, (Castelnau, 1872)

Introduction

The Whiskered Prowfish is a rarely observed species that closely resembles the Red Indian Fish, Pataecus fronto.

Identification

The Whiskered Prowfish is a highly compressed species that has a very narrow caudal peduncle. It has a single dorsal fin that originates in front of the eyes. The colouration of this fish is variable. It can be brown or orange with white or pink blotches or red lines.

The distinctive "whiskers" or chin warts that bestow the species its common name are also the best way to identify the species. Its close relative, the Red Indian Fish has similar, but much smaller whiskers. The two species can also be distinguished by positions of the dorsal and caudal fins, which are joined in the Red Indianfish and separate in the Whiskered Prowfish.

Habitat

The Whiskered Prowfish is uncommon. It is occasionally seen in floating seaweed and sometimes in crayfish pots. Steve Dreezer (see photos) reports that this species is found in sponge gardens, among sponges that closely match its colouration.

Distribution

The Whiskered Prowfish is is endemic to Australia, occurring in South Australia and southern Western Australia.
