Depressed wife finds healthy sea creature (4,5)
I believe the answer is:
blue whale
'sea creature' is the definition.
'blue whale' can be an answer for 'creature' (type of animal). I'm not certain of the 'sea' bit.
'depressed wife finds healthy' is the wordplay.
'depressed' becomes 'blue' (I've seen this in another clue).
'wife' becomes 'w' (abbreviation).
'finds' means one lot of letters go next to another.
'healthy' becomes 'hale' (hale can mean fit and healthy).
'blue'+'w'+'hale'='BLUE WHALE'
Can you help me to learn more?
(Other definitions for blue whale that I've seen before include "World's largest mammal" , "there's nothing bigger" , "Largest living animal" , "World's largest animal" .)
