Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Elasmobranchii (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) > Oxynotidae (Rough sharks)
Etymology: Oxynotus: oxys (Gr.), sharp; notos (Gr.), back, referring to its keeled back (“dorso carenato”). (See ETYFish);  paradoxus: Latin for strange or contrary to expectation; Frade was not sure if this shark, with its first dorsal spine directed backward instead of forward, represented a new species or an aberrant form of O. centrina. (See ETYFish).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00160 - 0.00860), b=3.15 (2.94 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.60 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
Climate Vulnerability (Ref. 125649):  Moderate vulnerability (36 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 6.48 [1.20, 33.69] mg/100g; Iron = 0.264 [0.061, 0.871] mg/100g; Protein = 19 [17, 21] %; Omega3 = 0.267 [0.088, 0.854] g/100g; Selenium = 15.4 [4.5, 48.7] μg/100g; VitaminA = 8.94 [1.81, 45.35] μg/100g; Zinc = 0.358 [0.175, 0.690] mg/100g (wet weight);
