Creature providing quiet on Noah's boat (5)
I believe the answer is:
shark
'creature' is the definition.
(I have seen 'Predatory creature ' mean 'shark' so perhaps 'creature' could also mean 'shark')
'quiet on noah's boat' is the wordplay.
'quiet' becomes 'sh'.
'on' says to put letters next to each other.
'noah's boat' becomes 'ark' (I've seen this before).
'sh'+'ark'='SHARK'
'providing' is the link.
(Other definitions for shark that I've seen before include "danger at sea" , "Predatory 5 dn" , "Predatory fish (or person?)" , "Large ferocious fish" , "eg Jaws" .)
