وصف مختصر
الوصف الخارجي | قياسات المظهر الخارجي
This species is distinguished by the following set of characters: the disc is weakly rhomboidal; preorbital snout is moderately short, its length 19-22% DW and rather broad, angle 117-127°, with a distinct apical lobe; lateral apices are narrowly rounded; the orbits moderately large, usually strongly protruding (particularly in young); 1-2, mostly heart-shaped suprascapular denticles which are not preceded before and after by a row of smaller primary denticles; secondary denticle band is developed before birth; dorsal surface of juveniles (smaller than 370 mm DW) are dark spotted or with spots and weak reticulations, subadults and adults (exceeding 390 mm DW) are more strongly reticulated; dorsal tail of juveniles has 3 rows of spots before caudal sting, faint dark saddles beyond sting (no alternating black and white bands on tail); tail uniformly dark ventrally; 146-152 pectoral-fin radials; 123 vertebral centra (excluding synarcual), 24 including synarcual 124 (Ref. 110363)
Depth distribution is not well documented, but this species is primarily in shallow water from near the shore to at least 45 m depth (Ref. 110363). Enters estuaries and brackish water (Ref. 114953). The largest specimen (140 cm WD) is a pregnant female with 2 embryos (30 cm WD) (data not year published); the smallest confirmed adult male is 112 cm WD (Ref. 110363); born at ca. 29 cm WD. Produces litters up to 4 pups (Ref. 114953).
