PR agent served sea cucumber (7)

I believe the answer is:

trepang

'sea cucumber' is the definition.
(trepang is a kind of sea cucumber)

'pr agent served' is the wordplay.
'served' indicates anagramming the letters.
'pr'+'agent'='pragent'
'pragent' is an anagram of 'TREPANG'.

(Other definitions for trepang that I've seen before include "Chinese delicacy" , "Chinese food" , "Sea cucumber" .)

I've seen this clue in The Telegraph.
