Andean beasts (6)
I believe the answer is:
llamas
'andean beasts' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for llamas that I've seen before include "Andean pack animals" , "Camel-like animals" , "Sal and Mal for the animals" , "domesticated guanacos" , "South American cud-chewing animals" .)
