The Talang queenfish has yet to be classified by the IUCN.
An elongated, streamlined, predatory fish of the Indian and west Pacific Oceans, the Talang queenfish (Scomberoides commersonnianus) may be recognised by its vivid, silvery body and relatively small fins. This powerful fish has rather short anal and dorsal fins, with the rear of the fins being reduced to just small spines, and a blunt snout and large mouth, armed with several rows of fine teeth. The attractive, bright, silver body contrasts with golden yellow streaks on the sides and dark yellow fins, while five to eight distinct dark blotches also run above the lateral line. The upperside of the Talang queenfish is sometimes tinged with dark green, and white on the underside (2) (3).
The Talang queenfish is found only in tropical waters of the Indian and west Pacific Oceans. Although it is found as far west as eastern Africa and as far east as Japan (3), the greatest abundance of the Talang queenfish occurs from south-east Asia to northern Australia (3).
The Talang queenfish is primarily found in coastal reefs to depths of 80 metres, but is also found in brackish water (2) (3).
The diurnal Talang queenfish is a voracious predator that feeds on small fish, crabs and squid living near the bottom of the sea (2) (3) (4). Breeding occurs between September and March when the male and female simultaneously release thousands of sperm and eggs into the water for external fertilisation. The developing larval fish drift passively within the ocean currents, with adult Talang queenfish reaching sexual maturity at four to five years of age (3) (5). Although it is not a true shoaling fish, the Talang queenfish does form small groups (2) (3) (4).
Currently, there are no known threats to the Talang queenfish, as it is of only minor value in commercial and game fishing (3).
There are currently no known conservation plans targeting the Talang queenfish.

- Anal fin: in fish, an unpaired fin on the under surface of a fish, behind the anus.
- Brackish: slightly salty water, usually a mixture of salt and freshwater, such as that found in estuaries.
- Diurnal: active during the day.
- Dorsal fin: the unpaired fin found on the back of the body of fish, or the raised structure on the back of most cetaceans.
- Fertilisation: the fusion of gametes (male and female reproductive cells) to produce an embryo, which grows into a new individual.
- Larvae: stage in an animal’s lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
- Lateral line: a row of receptors that can detect movement via vibrations in water. The receptors are typically embedded in the skin, and in fish they form a line along the sides of the body.
