Shaw's Cowfish, Aracana aurita (Shaw 1798)

More Info


Distribution

Widespread in the southern half of Australia, from Newcastle, New South Wales, to Kalbarri, Western Australia. Shaw's Cowfish inhabit rocky reefs and seagrass beds in sheltered bays, harbours, and coastal waters in depths of 10-160 m.

Features

Dorsal fin 10-11; Anal fin 10-11; Caudal fin 11-12; Pectoral fin 11-12.
Body encased in a rigid box-like carapace comprised of large sculptured bony plates, with large recurved spines on bony ridges; dorsal and anal fins opposite and far back on the body; bony plates on tail base well developed, almost encircling tail in adults; lines on snout almost horizontal.

Size

To 25 cm

Colour

Males and females are sexually dimorphic. Males are brightly-coloured, with pale blue wavy lines and spots over an orange background. Females and juveniles have a pale orange to pale brown background with irregular brown and white wavy lines or stripes.

Feeding

Feeds on a range of benthic invertebrates, often exposing prey by blowing jets of water onto the sediment.

Similar Species

The lines on the side of the face of both male and female Shaw's Cowfish are more-or-less horizontal, whereas those of the closely-related Ornate Cowfish are more angled. Male Ornate Cowfish also have a distinct hump on the snout. Female Ornate Cowfish also have deeper bodies and narrower stripes.

Etymology

The specific name is from the Latin auritus (= eared, having ears or having the form of an ear) in reference to the large horn-like spine above each eye that resemble ears.
