Yellowspotted trevally
The yellowspotted trevally, yellowspotted kingfish, goldspotted trevally, or tarrum, ''Carangoides fulvoguttatus'', is a widespread species of large inshore marine fish in the jack family Carangidae. The yellowspotted trevally inhabits the tropical and subtropical waters of the western Indo-Pacific region, from South Africa in the west to Japan and Australia in the east. The species is known to grow to a maximum length of at least 1.2 m, and is distinguished by gill raker and fin morphology, as well as the distinctive golden spots which give the fish its name. The yellowspotted trevally generally prefers inshore rocky and coral reefs, but is occasionally found over deep offshore sand banks to a depth of 100 m. It is a predatory fish, taking fish, cephalopods, and crustaceans, and shows diet partitioning with other trevallies in studies conducted in Australian waters. Reproduction is poorly studied, although observational evidence suggests spawning occurs in aggregations, probably during summer in South Africa. It is generally of minor importance to commercial fisheries throughout its range, but is considered an excellent sportfish by anglers and spearfishermen, and a good table fish.
==Taxonomy and naming==
The yellowspotted trevally is classified within the genus ''Carangoides'', a group of fish commonly known as jacks and trevallies. Carangoides falls into the jack and horse mackerel family Carangidae, of the order Perciformes, in the suborder Percoidei.
The species was first described by the naturalist Peter Forsskål in 1775 based on the holotype specimen taken from the waters of the Red Sea. He named the species ''Scomber fulvoguttatus'' relating the species to the true mackerels as during this period the family Carangidae had yet to be established. The species was later transferred to ''Caranx'' and then to ''Carangoides'', where it has remained. The species was independently renamed a number of times, the first as ''Tarrum emburyi'' by Gilbert Percy Whitley, a name which was commonly used and later transferred into ''Caranx'' and ''Carangoides''. Some 15 years later, Whitley again assigned the fish to a new species and genus name, ''Ferdauia claeszooni'', but this genus was soon synonymised with ''Carangoides'', and this name, as well as ''Tarrum emburyi'', was shown to be a junior synonym of ''Carangoides fulvoguttatus''. The common name 'tarrum' is still used in Australia for the fish, but is also widely misapplied to similar species.〔
