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).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Afterflossenstacheln: 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     Fachlexikon (Englisch) (z.B. 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).

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Bears two young (Ref. 5578). Size at birth between 15 and 17 cm (Ref. 244).

Estimates based on models

Preferred temperature (Ref. 123201): 12.8 - 18.4, mean 15.3 °C (based on 18 cells).
Phylogenetic diversity index (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).
Trophic level (Ref. 69278):  4.2   ±0.58 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec=2).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
