The soft rayed parts of the anal, dorsal and caudal fin are pale yellow and the pectoral fin as well as the spiny part of the anal fin are also pale yellow.

Distribution

Eubleekeria splendens occurs in the Indo-West Pacific from India in the west, to Papua New Guinea and Fiji to the east, Japan to the north, down to Australia in the south. It has been recorded in the waters of such countries as Tanzania, Madagascar, Mauritius, and is also known to live in the Red Sea.

Habitat and biology

Eubleekeria splendens lives in marine or brackish waters at a maximum depth of 100 metres. It is found in waters with a muddy or sandy mud substrate. It occurs near coasts and in estuaries. Smaller individuals may be found in mangrove creeks. It occurs in schools and feeds on smaller fish, crustaceans, foraminiferans, and bivalves, it is also known to feed on plants. In northern Australia spawning occurs in October.

Utilisation

Eubleekeria splendens is subject to some fishing and is marketed in south-east Asia either fresh or preserved by drying and salting. It is also sometimes made into fish meal.

Taxonomy

Eubleekeria splendens was first formally described as Equula splendens in 1829 by the French anatomist Georges Cuvier (1769-1823) with the type locality given as Chennai. It was placed within the subgenus Eubleekeria within the genus Leiognathus by Henry Weed Fowler in 1904. Within Leiognathus this species and L. jonesi and L. rapsoni, together with a new species L. kupanensis, were regarded as a species complex but Eubleekeria is now recognised as a valid genus with E. splendens as its type species.
