Dalhousie hardyhead

The Dalhousie hardyhead (Craterocephalus dalhousiensis) is a species of silverside in the family Atherinidae.

[1] It is endemic to the warm waters of Dalhousie Springs in the Lake Eyre basin, Australia, along with the similar Craterocephalus gloveri.

[2] It inhabits shady areas in tropical freshwater streams at 20-39 °C, but has been recorded at 41.8 °C.

A dark midlateral band runs from the snout to the base of the caudal fin.

Two to three rows of pigmented scales form discontinuous lines below the midlateral band.
