Returned list of details with bit of fish - a snapper? (9)
I believe the answer is:
alligator
'snapper?' is the definition.
(an animal which 'snaps')
'returned list of details with bit of fish a' is the wordplay.
'returned' says the letters should be written backwards.
'list of details' becomes 'rota' (I am not sure about this - if you are sure you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'bit of fish' becomes 'gill' (fish have gills).
'rota'+'gill'+'a'='rotagilla'
'rotagilla' backwards is 'ALLIGATOR'.
Can you help me to learn more?
(Other definitions for alligator that I've seen before include "Croc's close relative" , "one bites voraciously?" , "Broad-snouted snapper?" , "It could be in zoo" , "Amphibious reptile" .)
