Any creature supported by twins (5)

I believe the answer is:

biped

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

'any creature' is the definition.
'biped' can be an answer for 'creature' (biped is a kind of animal). I am not certain of the 'any' bit.

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

Can you help me to learn more?

(Other definitions for biped that I've seen before include "One walking on two feet" , "One walking on two legs" , "Two legged creature" , "Two-legged creature" , "One standing on two feet" .)

I've seen this clue in the Evening Standard.
