Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 0; गुदा कांटा: 0. A large, fairly stocky, catshark with large and small black spots and sometimes white spots covering dorsal surface, saddle markings obsolete, small anterior nasal flaps that do not reach the mouth, no nasoral grooves, labial furrows on lower jaw only, second dorsal fin much smaller than first (Ref. 244)

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

A common inshore and offshore shark found on the continental shelf over rough, even rocky or coralline ground, and algal-covered bottoms. Found at depths of 1 or 2 m to at least 125 m. Feed on bottom-living invertebrates such as mollusks and crustaceans and on demersal fishes (e.g. sharks, S. canicula). Oviparous (Ref. 50449). Utilized fresh and dried salted for human consumption, and processed into fishmeal. May attain 170 cm (Ref. 27000).

Life cycle and mating behavior Maturities | पुनरुत्पत्ति | Spawnings | Egg(s) | Fecundities | लार्वा

Oviparous, with a single egg per oviduct (Ref. 244). Embryos feed solely on yolk (Ref. 50449). Size at hatching about 16 cm (Ref. 244).
