Braless predators of South America? Huge number! (8)
I believe the answer is:
zillions
'braless predators' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'of south america? huge number' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'south' could be 's' (abbreviation) and 's' is located in the answer.
'number' could be 'l' (L is an example) and 'l' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for zillions that I've seen before include "Trillions and trillions" , "fantastic crowds" .)
