Elasmobranchii (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 ) .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 60 - 1490 m (Ref. 26346 ), usually 400 - 1400 m (Ref. 10717 ). Deep-water; 70°N - 56°S, 180°W - 180°E

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Eastern Atlantic: Iceland along Atlantic slope to Algoa Bay, South Africa (Ref. 247 , 5578 ). Western Pacific: southern Honshu in Japan, southern Australia, New Zealand. Occurrence in the Western Central Pacific uncertain (Ref. 31367 ). Eastern Pacific: southern Chile to northern Peru (Ref. 38549 ).

Length at first maturity / Size / Weight / Age

Maturity: L m 97.8 , range 70 - 111 cm
Max length : 127 cm TL male/unsexed; (Ref. 122636 ); max. published weight: 8.7 kg (Ref. 122636 )

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 0. A longnose dogfish with a long, 1st dorsal fin and no subcaudal keel (Ref. 5578 ). Grey-brownish in color (Ref. 6577 ).

Biology     Glossary (e.g. epibenthic)

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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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 ):  PD 50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00182 (0.00116 - 0.00285), b=3.16 (3.03 - 3.29), 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. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (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 = 10.1 [1.8, 32.4] mg/100g ; Iron = 0.269 [0.065, 0.708] mg/100g ; Protein = 20.8 [17.8, 23.0] % ; Omega3 = 0.306 [0.117, 0.971] g/100g ; Selenium = 18.6 [5.3, 51.7] μg/100g ; VitaminA = 12.6 [3.3, 42.6] μg/100g ; Zinc = 0.267 [0.129, 0.562] mg/100g (wet weight); based on nutrient studies.
