A tusked sofa that rules the ice.
Walrus vs Cheetah
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.
Cheetah
Acinonyx jubatus
A cheetah's tail is a rudder. It steers mid-sprint like a boat.
They prefer gazelles and other speedy snacks they can outrun.
Who do YOU think wins?

Cheetah
The land-speed record in spots.
