Yabby is a name given in Australia to two different kinds of crustacean.
* The Freshwater yabby is a crayfish of the genus Cherax (infraorder Astacidea, family Parastacidae). They are often caught for food. A widespread species is the common yabby, Cherax destructor.
* The Marine yabby is a ghost shrimp (infraorder Thalassinidea), which lives in deep burrows in the intertidal zone. They are used as bait for fishing, especially in Queensland and northern New South Wales. A common species in south-eastern Australia is the Bass yabby, Trypaea australiensis.
The name is derived from the word yabij in the Aboriginal language Wemba. Aboriginals believed if eaten it would increase the male's fertility.
They live in dams, waterholes, billabongs, creeks, irrigation channels, etc (inland "still" waters) of mainland Australia. Originally they were native to the Darling and Murray river catchment areas and other close smaller catchments
looks like a lobster to me.
