Biology:Hypseleotris
Hypseleotris, or carp gudgeons,[1] are a genus of small fresh and brackish water fishes in the family Eleotridae. Fish of this genus are found in rivers and estuaries connected to the tropical Indo-Pacific region.[2] They are sometimes seen in the aquarium trade; especially H. compressa.
Hypseleotris species are opportunistic predators, feeding on zooplankton, small crustaceans and other benthic invertebrates. Mostly pelagic, Hypseleotris often aggregate in small schools but become territorial during breeding,[3] which typically occurs in spring.
Species
Hypseleotris is made up of 23 species divided into 3 major clades.[4] The most basal clade contains 6 isolated species of euryhaline[5] gudgeons closely related to H. cyprinoides, with a distribution range extending from South Africa to eastern Melanesia and as far north as mainland China.[5]
The remaining species originated in Australia and would've diverged from other Hypseleotris sometime between 5 and 11 million years ago,[6] these species are organized based on their origins in Northwest and Southeast Australia respectively.[6][7] The Northwestern group is made up of 12[8] species which are endemic to the Northern Territory and Western Australia[3] with the exemption of H. compressa, which can be found across most of Australia and New Guinea.[3] The Southeastern clade is found across South Australia, Queensland and New South Wales, featuring 6 species and several hybrid/hemiclonal lineages[6] which consist of a single sex, a process known as hybridogenesis. The single sex species require gametes from the sexual species to reproduce and could be regarded as sexual parasites and in "closed populations" this sexual parasitism can cause the extinction of such populations.[1] It is likely that this reproduction involves androgenesis.[9]
