Arrived and left animal (5)
I believe the answer is:
camel
'animal' is the definition.
(thesaurus)
'arrived and left' is the wordplay.
'arrived' becomes 'came' (coming is a kind of arriving).
'and' is a charade indicator (letters next to each other).
'left' becomes 'l' (common abbreviation).
'came'+'l'='CAMEL'
(Other definitions for camel that I've seen before include "Beastly type" , "A ship, some say" , "Desert transport" , "Bearer of burdens" , "Pale brown - animal" .)
