Elasmobranchii (sharks and rays) > Squaliformes
(Sleeper and dogfish sharks) > Centrophoridae
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
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
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: Lm 97.8, range 70 - 111 cm
Max length : 127 cm TL male/unsexed; (Ref. 122636); max. published weight: 8.7 kg (Ref. 122636)
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).
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).
