Crossword Genius

Repeat search for a swimmer (10)

Ross

I believe the answer is:

parrotfish

'a swimmer' is the definition.
(parrotfish is a kind of aquatic vertebrate)

'repeat search' is the wordplay.
'repeat' becomes 'parrot' (parroting is a kind of repeating).
'search' becomes 'fish' (fishing is a kind of searching).
'parrot'+'fish'='PARROTFISH'

'for' acts as a link.

I've seen this clue in The Daily Express.
