Family Dalatiidae - Sleeper sharks
Order : Squaliformes Dalatiidae
Class : Elasmobranchii
No. in FishBase : Genera : 7 | Species : 10 Eschmeyer's Catalog of Fishes
Environment : Fresh : No | Brackish : No | Marine : Yes
Division : Marine
Aquarium : none
First Fossil Record :      
Remark : 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 (Ref. 557). The subfamilies are sometimes separated as independent families by various authors: Oxynotidae (Ref. 247); 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) (Ref. 48844) . Dalatiidae has dorsal fins without spines, first dorsal fin originating in front of pelvic fins but much closer to pelvic fins (Ref. 48844).

Species/Synonymy list for the family Dalatiidae as currently in FishBase

Important recommendation:

The list below must not be used as an authority reference synonymy list like those found in scientific published revisions, which must be the source to be used and cited eventually when they exist.

Rather, it reflects the current content of FishBase, and the progress with respect to synchronization with the Catalog of Fishes. However, we think it can be useful for users to assess the quality of information in FishBase, to start new work on the family, or to cross-check with other lists.

But we appreciate to be cited in publications when this list has been of any working value. In particular, for published scientific, we suggest then to cite it in the Material and Method section as a useful tool to conduct the research, but again, not as a taxonomic or nomenclatural authority reference.

Unless it is explicitly precised, the list is not complete, please search all original names published for the family in the Catalog of Fishes (genera, species), including those with uncertain or unknown status, that are not included in FishBase when they are not attached to a valid species.

This list uses some data from Catalog of Fishes (not shown but used to sort names).

The list ordered as follows:
