Shrimp maybe wearing odd cape (7)
I believe the answer is:
decapod
'shrimp maybe' is the definition.
(I know that shrimp is a type of decapod)
'wearing odd cape' is the wordplay.
'wearing' indicates anagramming the letters (wear can mean to become damaged).
'odd'+'cape'='oddcape'
'oddcape' anagrammed gives 'DECAPOD'.
(Other definitions for decapod that I've seen before include "Such as shrimp or lobster" , "Say, crab" , "Such as shrimp or crab" , "Crustacean with five pairs of walking limbs" , "lobster, say" .)
