Two conspicuous dermal folds on posterior margin of spiracles. Nostrils very large and oblique, separated from each other and from the mouth; anterior nasal flap small (not extending to inner nostril corner). Jaws moderately undulated; about 66/72 rows of oral teeth arranged in pavement. A row of pointed thorns along each rostral ridge, two/three additional thorns may occur on snout tip, single row of thornlets and thorns in front of orbit extending backward to level of spiracles; a median row of about 36 large, pointed thorns from nape to first dorsal fin and six between dorsal fins, median thorns flanked by two other shorter rows on the nape-shoulder area, additional short rows of thorns may be present on outer shoulders. Body covered with small dermal denticles, their crowns with a median posterior cusp, an extension from the median ridge, and short lateral cusp. Dorsal side greyish to greenish with numerous white ocelli-like spots; large black transverse blotch on ventral snout tip.

gives measurements expressed as proportions of total length. Very large ray with heavy shark-like body; head somewhat flattened, snout tip broadly rounded, bell-shaped, or slightly quadrangular; trunk thick, very wide at pectoral axil, then conical and tapering regularly rearward to caudal fin; tail rounded in cross section dorsally and almost flat ventrally. Apices of pectoral and pelvic fins broadly angular. Tail length from anterior cloaca 1.6 times precloacal length, 2.7 times its width at pectoral-fin insertion and 11.3 times its width at caudal-fin origin. Head rather short, its ventral length 21.0–23.2 % TL; snout short, its preoral length 10.2–10.9% TL, 1.7–1.8 times mouth width, 2.8–2.9 times internasal space; preorbital length 1.6–1.7 times interspiracular space, 1.7–1.8 interorbital space; interorbital space concave and broad; eyes moderately large, about as large as spiracles; spiracles oval with two conspicuous folds on posterior margin, the inner fold slightly smaller than the outer one.

MNHN MNHN MNHN MNHN 2003-0610 2003-0612 1992-0208 1992-0209 Nostril very large, elongate, oblique with inner end forming an angle of about 120°; nostril outer corner close to anterolateral margin of head; nostril length 1.2–1.3 longer than internasal space. Nostril anterior aperture slitlike, length 4.9 times in nostril length; posterior aperture long and circumflex-shaped, with shorter inner part, length 1.8 times in nostril length. Anterior nasal flap short-based, base length 3.2 times nostril length; with moderately long finger-like outer lobe and a narrow and low inner lobe; only slightly overlapping nostril, and not extending into internasal space. Posterolateral nasal flap narrow and extending about half-way along posterior margin of nostril. Mouth almost straight with thick lips and grooves around its corners; mouth width 1.2–1.3 times nostril length; jaws moderately undulated; teeth small, with blunt rhomboidal crowns, similar in both jaws, and arranged in pavement in 66/72 rows. Gill slits s-shape, distance between first gill slits 1.2–1.4 times distance between fifth gill slits.
