簡短描述 型態特徵 | 形態測量圖

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).

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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).印度-西太平洋: 波斯灣到菲律賓, 北至韓國與日本南部, 南至澳洲北部。 可能地在紅海與非洲東部與南部。
