Family Diceratiidae - Double anglers (Ref. 07463) or Doublespine Seadevils (Ref. 86949)
Order : Lophiiformes Diceratiidae
Class : Teleostei
No. in FishBase : Genera : 2 | Species : 7 Eschmeyer's Catalog of Fishes
Environment : Fresh : No | Brackish : No | Marine : Yes
Division : Marine
Aquarium : none
First Fossil Record :      
Remark : From Nelson (1994). Distribution: Atlantic and Indo-West Pacific. Tropical and subtropical; continental shelf or slope. Pelvic fin small and connected with cleithrum (Ref. 07463). Distinguishing character: Metamorphosed females of this family uniquely having an exposed second, light-bearing, dorsal-fin spine at the head, directly posterior to the illicium. This distal light organ is conspicuous in specimens approximately less than 3 cm, otherwise retracted in larger specimens. Possessing well-developed sphenotic spines, quadrate and articular spines, 3 pectoral radials, and notably, close-set dermal spinules covering the skin entirely along with the illium and the proximal part of the esca. Lone recorded juvenile metamorphosed male, measuring 1.4 cm in length, with large, laterally directed eyes and nostrils, a pair of denticular teeth on the upper jaw and two transverse series with 4 - 5 each of denticular teeth on the lower jaw, and presence of dermal spinules. Males are free-living with the indication of never becoming parasitic. Female larvae, two on record measuring 0.7 - 1.05 cm, with short and deep, almost globose body; skin very inflated with even subdermal pigmentation throughout; average-sized pectoral fins not surpassing the dorsal and anal fins in length; 5 - 7 dorsal-fin rays, 4 anal-fin rays (very rarely 5), 13 - 16 pectoral-fin rays, and 9 caudal rays (very rarely 8; 1 simple + 6 bifurcated + 2 simple). Largest recorded female specimen, Diceratias pileatus, measures 2.75 cm. Lone metamorphosed male recorded measures 1.4 cm (Ref. 86949).
Etymology : Greek, di = two, double + Greek, keras or keratos = horn, horned (referring to the two conspicuous dorsal-fin spines in the larvae and young females) (Ref. 86949).

Species/Synonymy list for the family Diceratiidae 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:
