Question

Which is the largest arboreal animal?

Answer 1

Some of these creatures spend a lot of their time in trees (i think that's what arboreal means):

The Leopard

Gorilla

Orangutan

Boa Constrictor  

Answer 2

when u say large, do u mean in size or weight?

Answer 3

Firstky i wish stop the assumption that leapards are bigger than Jaguars, Jaguars are bigger and heavier. I have worked with every type of big cat and know difference. So yes a jaguar would be the largest

Answer 4

Just a stab, and this of course is open to your interpretation of how arboreal they have to be to qualify, but I'd say orangutans, which probably beat out leopards by a smidge, depending on how you measure.
