Animal Species:Rhinoceros Leatherjacket, Pseudalutarius nasicornis (Temminck & Schlegel, 1850)
The Rhinoceros Leatherjacket is one of the leatherjacket species that has the dorsal spine positioned in front of the eyes. Usually found in deeper waters, it may occasionally be found in shallow seagrass habitats.
Standard Common Name
Rhino File-fish, Rhinoceros Filefish
The species is best recognised by the placement of the first dorsal spine, which is well forward of the eyes. The body is cream coloured, with two dark lines on the upper half of the body. The tail has a dark spot ringed in white or cream.
The species grows to 18 cm in length.
The species is found throughout the West-Pacific. In Australia its 'officially recorded' distribution appears to be restricted to southern Queensland and northern New South Wales although the Australian Museum collection contains specimens well outside this range.
