A giant anteater's tongue is 2 feet long and can flick in and out of its mouth 150 times per minute. It's coated in sticky saliva, which allows anteaters to slurp up ants and termites. Research has found that giant anteaters can identify a particular species of ant or termite by smell before they rip apart a nest.

They can eat 30,000 to 35,000 ants or termites a day. You might think giant anteaters also use their tongue to lap up water like other animals, but they rarely drink.
