|Scientific Name:||Etmopterus carteri|
|Species Authority:||Springer & Burgess, 1985|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Reviewer(s):||Kyne, P.M., Heupel, M.R. & Simpfendorfer, C.A. (Shark Red List Authority)|
A poorly known apparently rare deepwater species recorded only from the Caribbean coast of Colombia on the upper continental slope at depths of 283 to 356 m. Substantial exploratory trawling in the southern Caribbean Sea caught only a limited number of specimens. Biology is essentially unknown. No information is available on interactions with fisheries, although is likely to be infrequently encountered due to its rarity and very small size (maximum size 21 cm total length). Its restricted geographic and bathymetric range, as presently known, may be cause for concern if it is being taken as bycatch in any fisheries. However, insufficient information is presently available to assess the species beyond Data Deficient.
|Range Description:||As presently known, restricted to a small area of the Caribbean Sea off Colombia. More research is required to better define geographic range, but probably a naturally restricted species.|
|FAO Marine Fishing Areas:||
Atlantic – western central

|Population:||Not known, but apparently a rare deepwater species. Substantial exploratory trawling in the southern Caribbean Sea has revealed only a limited number of specimens (Springer and Burgess 1985).|
|Habitat and Ecology:||
A poorly known small deepwater shark recorded from the upper continental slopes at depths of 283 to 356 m (Springer and Burgess 1985, Compagno in prep a). It is possibly also epipelagic. Essentially nothing known of its biology. Development is probably ovoviviparous (aplacental viviparous) (Compagno in prep a). Maximum known size 21.2 cm total length (TL). Size at birth is unknown. Adults of both sexes recorded at sizes 18 to 21 cm TL (Springer and Burgess 1985).
Life history parameters
Age at maturity (years): Unknown.
Size at maturity (total length): Adults known from 18 to 21 cm TL.
Longevity (years): Unknown.
Maximum size (total length): 21.2 cm TL.
Size at birth (cm): Unknown.
Average reproductive age (years): Unknown.
Gestation time (months): Unknown.
Reproductive periodicity: Unknown.
Average annual fecundity or litter size: Unknown.
Annual rate of population increase: Unknown.
Natural mortality: Unknown.
None known. Of no importance for fisheries because of its extremely small size. Probably encountered only very infrequently by fisheries.
None known, probably discarded (probably too small to be utilised).
|Conservation Actions:||None in place. Like many deepwater chondrichthyan species more information on biology, ecology and importance in fisheries are required. Any expanding deepwater fisheries in the region (which could impact its habitat and population) need to be carefully monitored and managed.|
