Etmopteridae (Lantern sharks)
Etymology: Etmopterus: Greek, ethmos, -ou = sieve or ethmoides bone + Greek, pteron = wing, fin (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態学
海; 深さの範囲 25 - 1200 m (Ref. 106604). Deep-water; 40°N - 45°S
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).

Maturity: Lm ?, range 33 - ? cm
Max length : 35.0 cm TL オス/雌雄の選別がない; (Ref. 36137); 33.0 cm TL (female)
背面の脊椎 (合計) : 2; 肛門の骨: 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).
