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