Glover'S Hardyhead

Distinguished from other hardyheads by a combination of the following characters (expressed in mean): greatest body depth (mean 4.9), least body depth (mean 10.3) both in SL; eye 3.0 in head; midlateral scale count (mean 31.4). Osteologically diagnosed by the combination of the following: dentition, shape of urohyal, medial wing of pelvic bone and premaxilla. Differs further in lacking ventral processes on fifth ceratobranchial for attachment of pharyngoclavicularis internus muscle (Ref. 26685).Description: first dorsal fin spines 6, 5-6; second dorsal fin Ii5, Ii5-6; anal fin Ii7, Ii6-7; pectoral fin Ii12, Ii10-13 (Ref. 26685).

Inhabits warm water (>20°C) of spring-fed pools. Upper temperature tolerance is probably not as high as C. dalhousiensis. Omnivorous. Only co-occurs with C. dalhousiensis in one spring (Ref. 44894).

Glover's hardyhead (Craterocephalus gloveri) is a species of fish in the family Atherinidae endemic to Dalhousie Springs in the Lake Eyre basin, Australia. The fish has a high thermal tolerance and inhabits warm, freshwater spring-fed pools and channels. It is listed as vulnerable on the IUCN Red List. The specific name honours John Glover (1935–1992) who was the Curator of Fishes at the South Australian Museum.
