Greenway's grunter (Hannia greenwayi) is a species of freshwater

ray-finned fish, a grunter from the family Terapontidae. It is endemic to the northern part of Western Australia
.

Description

Greenway's grunter is a small, slender golden to silvery-grey grunter which is covered in large scales, each with a dark margin and a dark blotch on the lower part of the

anal fin bases. The larger adult fish may develop thick, fleshy, lips and when caught individuals may show broad, vertical bars.[2] This species has a maximum standard length of 14 centimetres (5.5 in), although 8 centimetres (3.1 in) is a more common standard length.[3]

Distribution

Greenway's grunter is endemic to the

Kimberley region of Western Australia where it occurs in the Fitzroy River system and Isdell and Calder rivers.[2]

Habitat and biology

The adults of Greenway's grunter are found in moderately to swiftly flowing streams in both clear and turbid water where there is a mixed substrate of sand and rock. Its biology is little known, but in 1969 a collection of 100 specimens of this fish suggested that are found in fast flowing rapids where the water was green in colour and the visibility was as low as 30 centimetres (12 in). It is an omnivorous species feeding on algae and small invertebrates. The eggs are guarded and fanned by the male parent.[3] It is though likely that this species spawns in the wet season.[1]

Taxonomy and etymology

Greenway's grunter was first formally

James C. Greenway for his generous support of the American Museum of Natural History's Australian expedition on which the type was collected.[5]
