Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 2; गुदा कांटा: 0. A large gulper shark with a short, broad snout, a long, low 1st dorsal fin, short pectoral rear tips, and large, rough, leaf-like denticles (Ref. 5578). Dark grey or chocolate brown in color (Ref. 5578).

Found on or near the bottom of continental slopes; also found pelagically in the upper 1,250 m of water 4,000 m deep (Ref. 31367). Presumably feeds on fish and cephalopods (Ref. 6871). Ovoviviparous (Ref. 50449). Utilized and fishmeal and dried salted for human consumption (Ref. 247); meat and fins (low value) and liver oil (very high value), and occasionally for its mature eggs (Ref.58048).

Estimates based on models

Preferred temperature (Ref. 123201): 4.1 - 10.6, mean 7 °C (based on 498 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00214 (0.00165 - 0.00277), b=3.20 (3.13 - 3.27), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.3 se; based on diet studies.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (tmax=71; K=0.04-0.05; Fec=5-8).

Prior r = 0.14, 95% CL = 0.09 - 0.21, Based on 1 data-limited stock assessment.
