Point to healthy sea creature (5)
I believe the answer is:
whale
'sea creature' is the definition.
(creature of the sea)
'point to healthy' is the wordplay.
'point' becomes 'w' (West).
'to healthy' becomes 'hale' (hale can mean fit and healthy).
'w'+'hale'='WHALE'
(Other definitions for whale that I've seen before include "World's largest mammal" , "Maybe humpback" , "Large marine mammal" , "monster" , "Leviathan" .)
