Predatory creature rising with tide (4)
I believe the answer is:
flow
'tide' is the definition.
(thesaurus)
'predatory creature rising' is the wordplay.
'predatory creature' becomes 'wolf'.
'rising' shows that the letters should be reversed in order (going up in a down clue).
'wolf' back-to-front is 'FLOW'.
'with' is the link.
(Other definitions for flow that I've seen before include "Move along as a stream" , "Wolf (anag.)" , "Trickle" , "Current" , "Scapa - , Orkney anchorage" .)
