Boa
A rainforest squeeze with a calm face.
Boa vs Koala
Tonight's science rumble is set in the visitor lawn, now closed for SCIENCE. No snacks were harmed.
Boa
Boa constrictor

Phascolarctos cinereus

Almost only eucalyptus. Most of those leaves would upset other animals' stomachs.
Who do YOU think wins?

Koala
A sleepy specialist with surprising claws.
