Walrus
A tusked sofa that rules the ice.
Walrus vs Koala
Tonight's science rumble is set in the picnic meadow, sandwiches evacuated. No snacks were harmed.
Walrus
Odobenus rosmarus
A walrus mustache has hundreds of whiskers, each a sensor.
Clams, mostly. Sensitive whiskers find shells in the dark mud.
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.
