The story
A bee hummingbird weighs less than a paperclip and beats its wings 80 times a second. An Etruscan shrew's heart races over a thousand beats a minute, a pygmy marmoset fits in your palm, and a Paedophryne frog is smaller than a housefly.
What you'll learn
- Small bodies lose heat fast, so tiny animals must eat almost constantly.
- The bee hummingbird is the smallest bird in the world.
- The Paedophryne frog is one of the smallest vertebrates known.
- Kid takeaway: being small means solving different problems, not easier ones.
