Etymology: Eridacnis: Etymology not explained, possibly eri-, Greek intensive particle (i.e., very), and dakno (Gr.), bite, referring to “wide, angular” mouth of E. radcliffei. (See ETYFish);  sinuans: Latin for sinuous, probably referring to its slender body and/or long, ribbon-like caudal fin. (See ETYFish).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 0; Anale stekels: 0. A slender, dwarf catshark with 2 equal-sized dorsal fins and a long tape-like caudal fin (Ref. 5578). Grey-brown in color (Ref. 5578).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Found on the upper continental slope and outer shelf (Ref. 244). Feeds on small bony fishes, crustaceans and cephalopods (Ref. 244). Ovoviviparous (Ref. 50449), with 2 young in a litter (Ref. 244). Geographic or bathymetric segregation of populations by sex probably occurs as most specimens taken off Natal were male (Ref. 244).

Estimates based on models

Preferred temperature (Ref. 123201): 12.8 - 18.4, mean 15.3 °C (based on 18 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.6328   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.2   ±0.58 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec=2).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
