Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 0; गुदा कांटा: 0. A comparatively large, stout catshark with a broad, rounded snout and no labial furrows; 2nd dorsal much smaller than 1st (Ref. 5578). Pale grey-brown, paler below; juveniles with about 6 slightly darker saddles on the dorsal side which fade and become unmarked in adults (Ref. 5510).
Found on the continental shelf and upper slope, preferring areas with sand and mud bottoms (Ref. 5578). Feeds on benthic animals, mainly crustaceans and cephalopods, but also bony fishes, and other elasmobranches (Ref. 244). Oviparous (Ref. 50449). Can expand with air when disturbed (Ref. 244).
Oviparous, laying one egg-case per oviduct (Ref. 244). Embryos feed solely on yolk (Ref. 50449).
