Blind Shark, Brachaelurus waddi (Bloch & Schneider 1801)

More Info


Distribution

Endemic to eastern Australia from Moreton Bay, Queensland, to Jervis Bay, New South Wales. Records from the Northern Territory are yet to be confirmed. 
Inhabits rocky reefs, shorelines, and adjacent seagrass beds, sheltering in caves and under ledges during the day, moving out to feed at night.

Features

Caudal fin with its upper lobe at a low angle above body axis, with a strong terminal lobe and subterminal notch but no ventral lobe.

Feeding

Feeds on a variety of benthic invertebrates, including sea anemones, squid and crustaceans, as well as on small fishes.

Biology

Little is known of the life history of the Blind Shark. The species is aplacental yolksac viviparous, meaning that the young develop from eggs inside the uterus and are born live. Females produce litters of 7  to 8 young pups during late spring, that are born at a length of 17 cm TL.

Remarks

The common name Blind Shark refers to the habit of this species closing its eyes when removed from the water.

Similar Species

The closely-related Colclough's Shark has pale spots and flecks on the body, and a yellowish underside.

Etymology

Brachaelurus is from the Greek brachys meaning 'short", and ailouros meaning 'cat.
