इलाज़मौबरांकी (शारक और रेज़) (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) > Centrophoridae (Gulper sharks)
Etymology: Deania: -ia (Gr.), belonging to: American ichthyologist Bashford Dean (1867-1928), American Museum of Natural History, for his research on selachian fishes. (See ETYFish); calceus: Latin for shoe, from the Portuguese vernacular sapata for this and other squaliform sharks, e.g., Centroselachus crepidater, Somniosidae; also known as sapata branca, white shoe, allusion not explained, perhaps referring to how its gray-white body with a long snout resembles a velvet slipper [often misspelled calcea]. (See ETYFish).

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 2; गुदा कांटा: 0. A longnose dogfish with a long, 1st dorsal fin and no subcaudal keel (Ref. 5578). Grey-brownish in color (Ref. 6577).

Found on the outer continental and insular shelves and upper slopes (Ref. 247). Usually on or near the bottom but sometimes found well above it (Ref. 5578). Apparently in large schools (Ref. 5578). Feeds on pelagic bony fish, squid, octopus and shrimp (Ref. 5578). Ovoviviparous (Ref. 50449). Caught very rarely by demersal longline fisheries operating in deepwater of Indonesia. Utilized for its meat, fins (low value) and liver oil (very high value) (Ref. 58048).

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

Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Young possibly number 6 to 12 in a litter, as these were the number of fertilized eggs found in the uteri of some specimens (Ref. 247). Size at birth 29 to 34 cm (Ref. 26346). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 0.3 - 9.6, mean 5.1 °C (based on 991 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00209 (0.00103 - 0.00422), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.4 se; based on diet studies.

Generation time: 14.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (K=0.077-0.135; Fec=6-12; tm=25).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).

Climate Vulnerability (Ref. 125649): High vulnerability (62 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 6.67 [1.36, 34.84] mg/100g; Iron = 0.319 [0.075, 1.026] mg/100g; Protein = 20.9 [17.9, 23.1] %; Omega3 = 0.303 [0.112, 0.975] g/100g; Selenium = 17.8 [5.4, 52.0] μg/100g; VitaminA = 9.83 [2.22, 44.15] μg/100g; Zinc = 0.249 [0.120, 0.471] mg/100g (wet weight); based on nutrient studies.
