More Info


Distribution

West of Bunbury to north of Sahul Banks, Timor Sea, Western Australia, and the Townsville Trough, NE of Hinchinbrook Island, Queensland, to off Lakes Entrance, Victoria. The species is now rare south of Jervis Bay, New South Wales. Elsewhere the Endeavour Dogfish has a patchy distribution in the Indo-west Pacific.
Demersal on continental and insular shelves and upper slopes at depths of 128–823 m. 

Features

Snout moderately long and flat, preoral length 8–13% TL, ovate; upper teeth with a single, smooth-edged triangular cusp, relatively erect centrally in jaw, oblique laterally; lower teeth with oblique, serrated, blade-like cusps, cusps in males more erect and pointed. 
Lateral trunk denticles of adults with rhomboidal to nearly circular sessile crowns on very low thick pedicels, crowns close-spaced but not overlapping, with a short thorn-like to blunt medial cusp.
Second dorsal fin very small, 2.0–2.4 in height of 1st dorsal fin, its spine well posterior to pelvic fin rear tips; free rear tip of pectoral fin forming an elongate lobe.

Biology

Attains a maximum size of 101.7 cm total length (TL). Males mature at ~70–90 cm TL; females mature at ~85–90 cm TL (Ebert et al. 2013). Reproduction is aplacental viviparous, fecundity is very low, with two pups per litter every two years, and size-at-birth estimated at 35–37 cm TL.

Etymology

The species is named for the type locality: the Molucca Islands, Indonesia.
