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).

Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 33 - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 36137); 33.0 cm TL (female)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. A stout lanternshark with a short tail and small conical denticles, not forming conspicuous lines along the body (Ref. 5578). Brown above, becoming black ventrally with inconspicuous, elongated, broad black marks along the caudal fin and at its base (Ref. 5578).

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).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Estimates based on models

Preferred temperature (Ref. 115969): 7.7 - 16.5, mean 12.7 (based on 176 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00191 - 0.00758), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.56 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).
