Elasmobranchii (haaien en roggen) (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); barbouri: In honor of American herpetologist (and wealthy patron of science) Thomas Barbour (1884-1946), Director, Museum of Comparative Zoology, Harvard University, for the “constant assistance” he gave the authors in their studies of western North Atlantic sharks. (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 123201): 8.3 - 14.6, mean 10.6 °C (based on 47 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): 3.8 ±0.60 se; based on food items.

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec=2).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
