This small species of Aetomylaeus (reaching to about 72.0 cm DW) is distinguished by the following set of characters: dorsal surface is greyish brown with a series of usually 8 (sometimes 7) transverse pale bluish bands (which are sometimes faint), no dark spots or blotches; ventral surface is whitish, pectoral fins is dusky distally; tail is rather long (1.4-1.8 times DW); without stinging spine; short and narrow head; fleshy rostral lobe, relatively broad, short, with a rounded apex; teeth usually in 7 rows in each jaw, with a broad median row flanked by 3 smaller rows on each side; dorsal-fin origin level with pelvic-fin insertions; radials of pectoral-fin 84-88 (excluding concealed propterygial radials anterior of eyes); total vertebral centra (including synarcual) 83-93; males have 16-19 pelvic radials (excluding clasper); females have 20 or 21 pelvic radials (Ref. 103981).
Maximum depth reported taken from Ref. 9773.
Ciclo de vida ou comportamento de acasalamento
Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas
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). Gives birth to ~4 pups; born at ~17 cm WD (Ref.58048).
