Description
Family Dalatiidae
Distribution: Antarctic to Arctic , Northern and Southern Hemisperes, coastal and oceanic . Includes four subfamilies (Etmopterinae, Somniosinae, Oxynotinae, and Dalatiinae). Except in Etmopterinae , most members without spines in dorsal fin; luminous organs present (except in Somniosus pacificus), appearing as black dots mainly on ventral surface. Etmopterinae has grooved spines in both dorsal fins, caudal fin with subterminal notch . Oxynotinae has very high, and compressed body, triangular in cross section ; dorsal fins very high, each with a spine[1]. The subfamilies are sometimes separated as independent families by various authors : Oxynotidae[2]; Somniosidae (dorsal fins without spines, first dorsal fin originating in front of pelvic fins but much closer to pectoral fins) and Etmopteridae (dorsal fin with spines, teeth with prominent central cusp flanked by one or two smaller cusplets )[3] . Dalatiidae has dorsal fins without spines, first dorsal fin originating in front of pelvic fins but much closer to pelvic fins[3].The family Dalatiidae belongs to the Class Elasmobranchii (sharks and rays ) and the Order Squaliformes. It contains 18 genera and 49 species. It may be found in Marine environments and is primarily Marine. Members of this family are not used in the aquarium trade. Reproductively, most members of this family are bearers. The main mode of swimming of adult fish in this family is subcarangiform. Etymology of this family name : Greek, dalos, -ou = torch
Habitat
May be found at depths of 110 to 560 meters.
Biome: Saltwater . Demersal .
Ecology: Benthic
and epibenthic
on the continental shelf and upper slope
on soft bottoms
. Compagno (in prep. a) reports this species from depths of 110 to 735 m
, but more commonly 200 to 500 m.
Ovoviviparous, number of young average 10 (Acuña et al. 2003).
Feeding habits: crustaceans and small fishes
, deep-sea
shrimp Euphausia mucronata, Heterocarpus reedi and the myctophid Diogenichthys laternatus (Acuña et al. 2003).
