Animal misrepresented in art (3)

I believe the answer is:

rat

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

'animal' is the definition.
(rat is a kind of animal)

'misrepresented in art' is the wordplay.
'art' can be anagrammed to 'RAT'.
But, I am not clear how this is indicated.

Can you help me to learn more?

(Other definitions for rat that I've seen before include "Strike-breaker" , "Plague-carrying rodent" , "one escaping doomed vessel?" , "Treacherous rodent" , "one who deserts the sinking ship?" .)

I've seen this clue in the Evening Standard.
