Hippo
A floating boulder with kitchen-knife tusks.
Hippo vs Cheetah
Tonight's science rumble is set in the picnic meadow, sandwiches evacuated. No snacks were harmed.
Hippo
Hippopotamus amphibius
Hippo sweat looks reddish. People called it blood-sweat. It is really a natural sunscreen.
Hippos graze grass at night. By day they soak and... argue.
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.
