vertebrata, bertulang belakang: 114 - 119. This medium-sized Myliobatis species (attaining at least 114.2 cm DW) is distinguished by the following set of characters: dorsal surface uniformly purplish brown to greenish brown, without dark spots or blotches; tail with a distinct, low ventral skin fold; stinging spine(s) are relatively long (longest spine 13.1-15.9% DW); adult males with interorbital space moderately concave; anterior margins of pectoral fin is straight to slightly convex; cranial fontanelle (visible in dorsal view without dissection) is relatively wide with slightly convex lateral margins; claspers of adult males 5.5-5.7% DW; predorsal length 63.6-68.6% DW; each jaw with 7 rows of teeth, with a broad median row flanked by three smaller rows on each side; pectoral-fin radials 85-92 (excluding rostral propterygial radials anterior of eyes); total vertebral centra (including synarcual) 114-119; males mature at about 65.0 cm DW (Ref. 132213).

Biologi     Daftar kata (contoh epibenthic)

Common inshore and offshore, demersal in intertidal habitats to depths of at least 220 m (Ref. 58048); also in coral reefs (Ref. 58534). Diet unknown, but presumably consists primarily of bivalves and other bottom-dwelling invertebrates. Caught occasionally by inshore, demersal longline fisheries. Utilized for its meat and cartilage (Ref. 58048). Ovoviviparous (Ref. 50449).

Siklus hidup dan perilaku kawin Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fekunditas | 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).
