Part of tortoise arguably shell-like (3)

Ross

I believe the answer is:

ear

'shell-like' is the definition.
(I've seen this before)

'part of tortoise arguably' is the wordplay.
'part of' indicates a hidden word.
'EAR' is hidden within 'tortoise arguably'.

(Other definitions for ear that I've seen before include "one hears" , "Hearing aid?" , "Aural organ" , "Discernment musicians need" , "See 8" .)

I've seen this clue in The Independent.
