opossum

I'm a little stuck... Click here to teach me more about this clue!

'creature' is the definition.
(opossum is a kind of creature)

I don't understand how the remainder of the clue works.

(Other definitions for opossum that I've seen before include "Type of marsupial" , "Native of America" , "New World marsupial" , "Large marsupial" , "Thick-furred marsupial of the Americas" .)

I've seen this clue in The Independent.
