Shaver returned large sea creature! (9)

Ross

I believe the answer is:

razorback

I'm a little stuck... Click here to teach me more about this clue!

'large sea creature' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'shaver returned' is the wordplay.
'shaver' becomes 'razor' (I've seen this in another clue).
'returned' becomes 'back' (I've seen this in other clues).
'razor'+'back'='RAZORBACK'

Can you help me to learn more?

(Another definition for razorback that I've seen is " One grunting".)

I've seen this clue in The Telegraph.
