Etymology: Rhynchobatus: Greek, rhingchos = snout + Greek, batis, -idos = a sting ray (Raja sp.) (Ref. 45335)springeri: Named for Stewart "Stew" Springer.
Eponymy: Stewart ‘Stew’ Springer (1906–1991) was a field naturalist who dropped out of Butler College (1929) but was awarded a baccalaureate by George Washington University (1964), by which time he was world-renowned as an expert on both the taxonomy and [...] (Ref. 128868), visit book page.

Descripción breve Claves de identificación | Morfología | Morfometría

This moderate-sized species is distinguished by the following set of characters: snout broadly wedge-shaped; preoral snout 16-22% of total length; eye small, length 3.1-4.0 in preorbital snout; interorbital space 2.2-2.7 in preorbital snout; mouth hardly bowed, with strong indentation on upper jaw near symphysis and strong protuberance on lower jaw; tooth rows in upper jaw about 52 (holotype); dorsal snout no spines; dorsal tip of snout with no rostral spines or spines; supraorbital spines small but well differentiated, extending from preorbit to end of spiracle; spines of mid-dorsal row relatively well developed; two obvious rows of small scapular spines on each side; origin of first dorsal fin over origin of pelvic fin bases; predorsal space 42-48% of total length; colour pale greyish green above with 3-4 rows of large, white spots extending along the tail; black pectoral marking distinct, usually closely surrounded with 4 white spots (occasionally 3); anterior pectoral disc with narrow whitish margin; orbital membrane with a pair of dark, widely spaced, recurved lines; interorbital space with no alternating light and dark markings; propterygial radials 1-8 + 20-23, mesopterygial radials 4-6, neopterygial radials 4-7, metapterygial radials 23-29, total radials 57-68 (inc. free radials); vertebrae with 12-14 synarcual centra, 18-28 monospondylous precaudal centra, 78-88 precaudal free centra, 33-40 diplospondylous caudal (free) centra, 113-126 total free centra, 127-139 total centra (including synarcual centra) (Ref. 84284).
Body shape (shape guide): elongated.

Biología     Glosario (por ej. epibenthic)

Apparently confined mainly to brackish coastal and estuarine habitats in shallow water (Ref. 84284). Diet unknown, but presumably similar to other wedgefishes. Males mature at around 115 cm TL (Ref. 114953), two male paratypes from Sarawak (Malaysia) (IPPS 2009–338, adult male 112.6 cm TL) and Thailand (CAS-GVF 2361 unreg) were fully mature at 113 and 125 cm TL respectively, suggesting that this species is a moderate-sized wedgefish rather than a large species (Ref. 84284).
