''Cherax depressus'', the orange fingered yabby, is an Australian freshwater
A relatively small species of yabby reaching a maximum of 10 cm (4 in) in length. Named the 'orange fingered' yabby due to the orange tipping on the end of their chelae (pincers).
These yabbies dwell in dug burrows alongside small creeks or ephemeral waterways and can survive dry conditions for several years by lying dormant in burrows sunk deep into the muddy creek beds, coming out into open water only during heavy rainful. They dig their burrows with their mega sized pincers, burrowing generally around 50–80 cm deep, but can dig deeper during droughts if necessary. Even when not in drought, the yabby will rarely emerge from its burrow chambers, making it a rarely seen yabby species.
Colour is highly variable and depends on the environmental conditions and habitat; yabbies can range from black, blue-black, dark brown, dark red, dark green, dark blue and brown-red. Although usually consisting of a brownish-red top side and a light or dark blue underside and legs.
Juveniles may be found inhabiting open water and small creeks as they slowly develop their digging skills. Adults will rarely venture outside their burrows unless mating or desperate for food.

but a relatively unknown species due to the fact that they are buried most of their life and are rarely seen.
Catching
These yabbies are very rarely hunted due to the factors such as them being 10 cm or less, very hard to track down burrows, nets useless as they arere rarely found in open water and them being a relatively unheard of crayfish species.References
