Espinhos dorsais (total) : 0. Taiwan angelshark Squatina formosa has broad pectoral fins with outer corner more obtuse and free rear tips narrowly subangular; nasal barbels apparently simple, narrow and tapered. Anterior nasal flaps smooth to weakly fringed; dermal folds on sides of head possibly with a triangular lobe. Rear tip of inner margin of pelvic fins reaching little beyond origin of first dorsal.

Estimates based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00293 - 0.01558), b=3.07 (2.88 - 3.26), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.8   ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100).
