Short Description
Original Diagnosis after LAST, WHITE & SÉRET, 2016 [23790]: A medium-sized Neotrygon of the kuhlii-complex (reaching at least 30 cm DW) with the following combination of characters: disc broader than long, width ~1.2 times length; pectoral apices narrowly rounded; snout rather fleshy, broadly angular, angle ~107°, length 1.7–2.1 times interorbital width; maximum width relatively well back on disc, length from snout tip to pectoral-fin insertion 1.8–1.9 times and disc width 2.5–2.6 times horizontal distance from snout tip to maximum disc width; preoral length 2.4–2.8 times mouth width; internasal distance 1.5–1.8 in prenasal length; interspiracular distance 13–15% DW; nostril length 2.8–4.1% DW; nasal curtain width 8–8.3% DW; small mouth, width 6.4–6.8% DW; horizontal distance from cloaca to caudal sting base ~55% of disc length; thornlets present in nuchal region, absent from tail in all sizes; dermal denticles absent; pectoral-fin radials 113 (based on new specimen); total vertebral centra (including synarcual) 133, trunk centra (including synarcual) 39; blue spots very small and sparse, largest spot on disc 0.3–0.5 times eye width; 0–6 (mean 3.0) blue spots on medial belt, largest ~2.1% DW; mask-like marking pronounced, not covered with dark peppery spots; ventral surface of disc and pelvic fins with broad dark greyish submarginal bands; ventral tail fold and adjacent tail bluish grey when fresh.
Diet: north-east Australia (data base: 131 specimens): Polychaetes were the most important prey category (71,5 %IRI), carids were the second most important prey category (24,5 %IRI) [14696].

Human uses
fisheries: commercial

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures [733]. Distinct pairing with embrace [17086]. Litters size at birth 16 cm (Ref. 37816); Java form born at 11-16 cm WD, Bali form born at ~17 cm WD. Gives birth to litters of 1-2 pups; no reproductive synchronicity [2539]. Inhabits sandy areas among coral reefs. A solitary species found on sandy bottoms near rocky or coral reefs [1658]. Usually found in deeper water but moves onto the reef flat and into shallow lagoons at high tide [1658]. Occasionally covers itself with sand, leaving only its eyes and tail visible (Ref. 37816). Feeds on crabs and shrimps [536]. A carnivore [17641]. Also Ref. 58534.
