Large mammal with cry that's audible? (5)
I believe the answer is:
whale
'large mammal' is the definition.
(whales are large mammals)
'cry that's audible?' is the wordplay.
'cry' becomes 'wail' (wailing is a kind of crying).
'that's audible?' indicates a 'sounds like' (homophone) clue (I've seen 'audible' mean this).
'wail' is a homophone of 'WHALE'.
'with' is the link.
(Other definitions for whale that I've seen before include "One wallowing in the drink" , "Largest animal" , "Large marine creature" , "Patch of oil, on water" , "one in the water?" .)
