Elasmobranchii (sharks and rays) > Rajiformes (Skates and rays) > Arhynchobatidae (Softnose skates)
Etymology: Sympterygia: Greek, syn, symphysis = grown together + Greek, pteryx = fin (Ref. 45335).
More on author: Cope.

Issue
Four nominal species of Psammobatis (asper, caudispina, chilcae, maculatus), all from Hildebrand, 1946, are considered valid in Eschmeyer (CofF ver. May 2011: Ref. 86870) following Chirichigno & Vélez (1998), but J. McEachran confirmed their synonym status of Sympterygia brevicaudata (Cope, 1877) (pers. comm., 11/2003).

Estimates based on models

Preferred temperature (Ref. 123201): 15.3 - 21, mean 19.5 °C (based on 100 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00288 - 0.01097), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
Nutrients (Ref. 124155):  Calcium = 42.7 [6.6, 208.3] mg/100g; Iron = 0.876 [0.232, 2.569] mg/100g; Protein = 17.6 [14.9, 20.1] %; Omega3 = 0.444 [0.145, 1.605] g/100g; Selenium = 11 [3, 37] μg/100g; VitaminA = 17.9 [5.8, 55.9] μg/100g; Zinc = 0.73 [0.34, 1.35] mg/100g (wet weight);
