Rhino
A tank that forgot it is an animal.
Rhino vs Koala
Tonight's science rumble is set in the visitor lawn, now closed for SCIENCE. No snacks were harmed.
Rhino
Ceratotherium simum
Rhinos have been on Earth for millions of years. They are living fossils with attitude.
White rhinos graze grass like giant lawn mowers.
Koala
Phascolarctos cinereus
A koala's fingerprint looks a lot like a human's. Weird science.
Almost only eucalyptus. Most of those leaves would upset other animals' stomachs.
Who do YOU think wins?

Koala
A sleepy specialist with surprising claws.
