Kurtus gulliveri, the nurseryfish, is a species of fish in the family Kurtidae native to fresh and brackish waters in southern New Guinea and northern Australia.[1] They can be found in estuaries, mangrove swamps, nipa swamps and slow-flowing rivers with high turbidity. This species can reach a length of 63cm (25inches), although most are far smaller: In a study of its morphology, 159 specimens were examined and the largest was 33cm (13inches), while the average was 14cm (06inches).[1] This species is famous for its unusual breeding strategy where the male carries the egg cluster on a hook protruding from the forehead (supraoccipital).[1] Females do not have a hook.[1] It feeds on crustaceans (especially prawn and shrimp), small fish and insect larvae.[2] This species is well regarded as food. The specific name honours a "Mr Gulliver" who collected the type, thought most likely to refer to Thomas Allen Gulliver (1847-1931) who worked on Australia's a post and telegraph services and who lived near the Norman River, Gulf of Carpentaria where he collected natural history specimens and where the type of this species was collected.[3]
