The species name amniculus is from the Latin meaning a small creek or stream, in reference to the habitat where these fish are often found.[1] Craterocephalus amniculus is recorded to be vulnerable to becoming an endangered species because of its restricted range, but the threats and information regarding this recording have not been verified or documented.[2]HabitatThe Darling River hardyhead can be found in a freshwater environment within a benthopelagic range. They are native to a subtropical climate. The average length of an unsexed male is about 5.5 cm or 2.2 in. This species can be located in New South Wales, Australia.[3] It populates itself in clear, steady, and slow water. They are recorded to be found in streams, creeks, and rivers at the surface of the water or in the shallow areas. They are occasionally found among plants and vegetation in the water, as well. It is common to find this species isolated or within groups of 10-15 fish. DescriptionThe Darling River hardyhead is identified by its compressed body, small mouth, and thin lips. The eyes of this species are large and silvery. They have short dorsal fins along with a forked tail. Its small scales rarely show up on the head. The back of the species is gold with a silver body. Also, a dark line runs across its side.[4] Breeding and spawning occurs in the middle of summer.[5] References1. ^{{cite web|last1=Thompson|first1=Vanessa|title=Darling Hardyhead, Craterocephalus amniculus|url=http://www.fishesofaustralia.net.au/home/species/1377|website=Fishes of Australia|accessdate=30 September 2014}} 2. ^{{cite web|title=Craterocephalus amniculus|url=http://www.iucnredlist.org/details/5487/0|publisher=International Union for Conservation of Nature and Natural Resources|accessdate=25 March 2013}} 3. ^{{cite web|title=Craterocephalus amniculus Crowley & Ivantsoff, 1990 Darling river hardyhead|url=http://www.fishbase.us/summary/Craterocephalus-amniculus.html|publisher=Fish Base|accessdate=25 March 2013}} 4. ^{{cite web|title=Darling River hardyhead |url=http://www2.mdbc.gov.au/subs/fish-info/native_info/darlingRiverHardyhead.html |publisher=Fish Factsheet |accessdate=25 March 2013 |deadurl=yes |archiveurl=https://web.archive.org/web/20130419094041/http://www2.mdbc.gov.au/subs/fish-info/native_info/darlingRiverHardyhead.html |archivedate=19 April 2013 |df= }} 5. ^{{cite web|title=Craterocephalus amniculus|url=http://eol.org/pages/994081/overview|publisher=Encyclopedia of Life|accessdate=25 March 2013}} Sources
