Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)): 0; Duri dubur 0; Sirip dubur lunak: 0; vertebrata, bertulang belakang: 98 - 102. Disc-width shorter than its length, width and length about 1,60 to 1,80 times in total length; dorsal fins more or less rounded, its base 1,25 times in its length (Ref. 39215).
Found on coral reefs; as well as mud or sandy bottoms, from shallow water to a depth of 100 m (Ref. 30573, Ref. 114953). Mainly feeds on invertebrates and small reef fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Males reaches maturity at 28 cm TL (Ref. 114953).
Life cycle and mating behavior
Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | 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).
