Scymnodon plunketi (Waite 1910)

More Info


Distribution

Off Port Macquarie, New South Wales to off Portland Victoria, and near Perth, Western Australia. Elsewhere the species is widespread with a patchy distribution in the Indo-west Pacific, from Mauritius to New Zealand. Inhabits continental and insular slopes at depths of 180-1,550 m, most commonly below 600 m.

Features

Vertebrae (precaudal) 84-85, (total) 114-115.  
Snout short (preoral length 5-8% TL), bluntly pointed; pectoral fins large, broad, tip and inner corner rounded.  Reaches 1.7 m.

Feeding

Feeds mostly on bony fishes and cephalopod molluscs.

Biology

Attains a maximum size of 170 cm total length (TL), and the species may live at least 39 years. Males mature at 100-120 cm TL and 18 years of age, and females mature at 130-145 cm TL and 29 years of age. Females produce litters of up to 36 pups, which are born at 32-36 cm TL. Reproduction is lecithotrophic viviparous and presumed to be asynchronous.

Fisheries

Taken as bycatch in bottom trawl and longline fisheries throughout its range.
