Diagnostic Description

provided by Fishbase
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

provided by Fishbase
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).

Migration

provided by Fishbase
Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Biology

provided by Fishbase
Occurs inshore and offshore, from the intertidal to at least 70 m depth (Ref. 9862); over soft substrates to at least 115 m (Ref. 103981). May enter brackish water. Feeds on worms, crustaceans, snails, and bony fishes (Ref. 12951). Ovoviviparous (Ref. 50449). With litters of up to 4 young. Size at birth about 17 cm WD (Ref. 6871). Caught frequently, but in lower numbers, by bottom trawl and inshore gillnet fisheries in some areas. Utilized for its meat, but of limited value due to its small size (Ref.58048).
