(See ETYFish); kistnasamyi: In honor of Nat Kistnasamy (b. 1938), Oceanographic Research Institute (Durban, South Africa), for “outstanding efforts and pioneering work” in the systematics and taxonomy of the chondrichthyan fauna of southern Africa.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00173 - 0.00727), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (45 of 100).
