Otter
A slippery wrestler who treats rivers like gyms.
Otter vs Cheetah
Tonight's science rumble is set in the picnic meadow, sandwiches evacuated. No snacks were harmed.
Otter
Lontra canadensis
River otters can stay underwater about 4 minutes.
Fish, crayfish, frogs — they eat lunch in the pool.
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.
