Join cetacean (not at sea) (11)

Ross

I believe the answer is:

concatenate

'join' is the definition.
(thesaurus)

'cetacean not at sea' is the wordplay.
'at sea' indicates anagramming the letters.
'cetacean'+'not'='cetaceannot'
'cetaceannot' with letters rearranged gives 'CONCATENATE'.

(Other definitions for concatenate that I've seen before include "String together" , "Link together in a chain" .)

I've seen this clue in The Independent.
