Type of marsupial (8)
I believe the answer is:
kangaroo
'type of marsupial' is the definition.
This is all the clue.
(Other definitions for kangaroo that I've seen before include "Native marsupial Down Under" , "Jumper of grey or red" , "Jumping animal" , "Illegal court of marsupial origin?" , "Marsupial (both parts 4's friends)" .)
