vertebrata, bertulang belakang: 200 - 205. This medium-sized species is distinguished by the following set of characters: dorsal surface smooth, no prominent thorns or tubercles, except for slightly enlarged granular denticles partially around orbital rims, and rather regularly distributed along midline from nape to near first dorsal-fin origin, none between dorsal fins and upper caudal fin; snout semi-translucent with elongated bluish spots giving stripe-nosed appearance, numerous small bluish spots covering the snout, pectoral, pelvic, dorsal, and caudal fins but not the central disc, on a sandy brown background with darker brown spots of varying sizes covering the disc, tail, fin bases, and fins, and sometimes giving the caudal peduncle a striped appearance, the outer edges of pectoral- and pelvic-fin margins blue, while lateral tail folds white or striped blue and brown and ventral surface white; nasal lamellae 37-41; upper jaw tooth row count ca. 60-75; post-synarcual centra 187-192; total vertebral segments 200-205; total pectoral skeleton radials 63-70 (Ref. 124452).

Life cycle and mating behavior Maturities | Reproduksi, perkembang biakan | Spawnings | Egg(s) | Fecundities | Larva

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 (Ref. 50449). Bears 2 to 4 young (Ref. 5578).
