African frog: there’s ten in French work (7)

Ross

I believe the answer is:

xenopus

'african frog' is the definition.
(frog native to Africa)

'there's ten in french work' is the wordplay.
'there's' is a charade indicator (letters next to each other).
'ten' becomes 'X' (Roman numeral).
'in french' becomes 'en' ('in' in French).
'work' becomes 'opus' (an opus is an artistic work).
'x' next to 'en' is 'xen'.
'xen'+'opus'='XENOPUS'

(Other definitions for xenopus that I've seen before include "frogs once used for pregnancy testing" , "African clawed toad" .)

I've seen this clue in The Times.
