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][2] This species is famous for its unusual breeding strategy where the male carries the egg cluster on a hook protruding from the forehead (supraoccipital).[2] Females do not have a hook.[2] It feeds on crustaceans (especially prawn and shrimp), small fish and insect larvae.[3] This species is well regarded as food.[4] 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.[5]

Biology

[edit]

The nurseryfish is considered euryhaline[6] and can be found in estuaries, mangrove swamps, nipa swamps and slow-flowing rivers with high turbidity[citation needed]. This species can reach a length of 63 cm (25 in),[4] although most are far smaller. In a study of its morphology, 159 specimens were examined and the largest was 33 cm (13 in), while the average was 14 cm (5.5 in).[2] Nurseryfish also have small, conical teeth arranged in bands and some in patches.[3] They are carnivorous.[3] Their spawning season is thought to be from June to January.[7]
