Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Proscylliidae (Finback catsharks)
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 ) .
More on author: Smith .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 180 - 480 m (Ref. 244 ). Deep-water; 4°S - 30°S

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Western Indian Ocean: confined to South Africa, Mozambique and Tanzania.

Length at first maturity / Size / Weight / Age

Maturity: L m   ? , range 37 - ? cm
Max length : 37.0 cm TL (female)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 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 ).

Biology     Glossary (e.g. 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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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 ):  PD 50 = 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. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (Fec=2). Fishing Vulnerability (Ref. 59153 ):  Low to moderate vulnerability (27 of 100).
