Australian marsupial in shock with a temperature (6)
I believe the answer is:
numbat
'australian marsupial' is the definition.
'numbat' can be an answer for 'marsupial' (numbat is a kind of marsupial). I am not sure about the 'australian' bit.
'in shock with a temperature' is the wordplay.
'in shock' becomes 'numb' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'temperature' becomes 't' (abbreviation).
'numb'+'a'+'t'='NUMBAT'
Can you help me to learn more?
(Other definitions for numbat that I've seen before include "one bright-eyed and bushy-tailed?" , "Termite-eating marsupial" , "insectivore" , "Australian native" .)
