توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
This large western Indian Ocean anacanthobatid species is distinguished by the following characters: grows to about 59.1 cm TL, with an extremely depressed pear-shaped, broad and long disc, its width 71-73% TL and length 76% TL, 0.9-1.0 times as wide as long and with rounded outer corners; head with dorsal length 34% TL, ventral length 41% TL and snout with preorbital length 28-29% TL, preoral length 30% TL, prenasal length 28% TL) long; its snout angle is 90-93°; the snout is terminally expanded as a rostral lobe, 12-13% of preorbital snout length and with a short, thin rostral filament; interorbital distance is rather wide, 4% TL; inner margin of posterior pelvic lobe is fused to root of tail along most of its length, with a short, pointed free tip; very short tail, its length from mid-vent to tail tip 35-36% TL and about half of body length from tip of rostral lobe to mid-vent; tail tapers from anterior part towards about mid-length of tail, becoming slightly broader and flattened in posterior third through lateral keels, and tapering again towards tip from about 2 cm before tip; rudimentary caudal fin with very short and low epichordal and without hypochordal lobe; the upper and lower surfaces of disc and tail are entirely naked and without papillae; colour of upper surface pale grayish-brown, ventral side anteriorly whitish to level of lower jaw and interbranchially, posterior part of disc and underside of tail pale grayish-brown with irregular pale brown blotches at transition from white to brown, the underside of posterior pelvic lobe medium grayish-brown, anterior lobes are dark brown with an indistinct white blotch near the tip and a distinct white blotch at anterior origin; upper jaw tooth rows 25-27; monospondylous vertebral centra 29, diplospondylous centra 102-112, total centra 131-141; the scapulocoracoid is subrectangular, the rear corner sharply marked; moderately large oval anterior fenestra without anterior bridge, one very large oval postdorsal and at least three small postventral fenestrae; pelvic girdle with massive ischiopubic bar with almost straight anterior and broad, shallow trapezoid posterior shape; prepelvic processes are very long and slightly inclined outwards, their length from axis of pelvic girdle maximum width 77.5-90.9% of pelvic girdle maximum width and 4.9-5.6 times median thickness of ischiopubic bar; differs from all other described anacanthobatids in the short tail, which also differentiates it from its morphologically closest congener, the allopatric Sinobatis bulbicauda; further distinguished from other anacanthobatid legskates in the western Indian Ocean (Anacanthobatis marmorata, Indobatis ori) by its large size and light coloration (Ref. 109333).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5020 [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
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
