Elasmobranchii (sharks and rays) > Rajiformes
(Skates and rays) > Anacanthobatidae
(Smooth skates) > Rajinae
Etymology: Anacanthobatis: Greek, ana = up + Greek, akantha = thorn + Greek, batis, -idos = a ray (Ref. 45335).
Springeria nanhaiensis Meng & Li in Chu et al., 1981 should be considered a questionable synonym of Sinobatis borneensis (Chan, 1965b) following Last & Séret (2008 ) in Ref. 94809.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 474 - 500 m. Deep-water
Western Pacific: type locality, South China Sea.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
