Dorsal spines (total): 2; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A stout lanternshark with a short tail and small conical denticles, not forming conspicuous lines along the body (Ref. 5578).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Western Atlantic: Virginia and Florida (USA), Uruguay and Argentina; reported off Suriname (Ref. 13608) and Brazil (Ref. 57911). Southeast Atlantic: off the eastern Cape and northern Natal in South Africa (Ref. 11228). Some reports of this species from the southeast Atlantic may be misidentifications of the recently described Etmopterus compagnoi (Ref. 36731).

Biology     Glossary (e.g. epibenthic)

Found on outer continental shelves and upper slopes on or near the bottom at depths of 100 to 1,000 m; also pelagic at depths of 70 to 480 m over water 2,240 m deep off Argentina (Ref. 247). Feeds on bony fish, octopus, squid and deep-water shrimp (Ref. 5578). Ovoviviparous (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00339 (0.00157 - 0.00730), b=3.12 (2.92 - 3.32), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.3   ±0.56 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100) .
Price category (Ref. 80766):   Unknown.
