What type of creatures are marrons and yabbies?

Answer 1

Marron
The marron Cherax tenuimanus is a large freshwater crayfish found in the south-west corner of Australia.

Recreational fishing for marron is tightly controlled, with a limited season, permits required and minimum sizes.

Marron is considered a luxury product and is the subject of a developing aquaculture industry in Western Australia and in other Australian states. Total Australian production of farmed marron was 30 tons in 1996.

Yabby
Yabby is a name given in Australia to two different kinds of crustacean.
* Freshwater yabbies are crayfish of the genus Cherax (infraorder Astacidea, family Parastacidae). They are often caught for food. A widespread species is the common yabby, Cherax destructor.
* Marine yabbies are ghost shrimps (infraorder Thalassinidea), which live 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.
