Etymology: Scymnodon: scymnus, an ancient name for some kind of shark, derived from a Greek word meaning young animal, cub or whelp; odon (Gr.), tooth, referring to large, triangular cutting teeth on lower jaw of S. ringens (See ETYFish); ringens: Latin for gaping, referring to its large, open mouth (“ore amplo, hiante”) (See ETYFish).

Краткое описание определительные ключи | морфология | морфометрия
колючие лучи анального плавника: 0. Black in color; small dorsal fin spines; short snout; small lanceolate teeth without cusplets in upper jaw and huge high, knife-cusped cutting teeth in lower jaw; mouth very wide and broadly arched; caudal fin with weak subterminal notch and no lower lobe (Ref. 247).
A rare species (Ref. 26346) inhabiting continental slopes (Ref. 247). Usually mesopelagic although taken most often near the bottom (Ref. 10717). Its razor-edged lower teeth is used to attack and dismember large prey (Ref. 247). Ovoviviparous (Ref. 205). Utilized dried salted for human consumption and for fishmeal (Ref. 247).

Estimates based on models
Preferred temperature (Ref. 115969): 4.2 - 11.4, mean 7.7 (based on 164 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00176 - 0.00861), b=3.14 (2.95 - 3.33), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278): 3.9 ±0.7 se; based on diet studies.
устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).
Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (46 of 100).
