One eye on watch
A dolphin sleeps with only half of its brain at a time, keeping one eye open to watch for danger.


Hidden warmth
Under all that white fur, a polar bear's skin is actually jet black.


A day slower than a year
On Venus, a single day lasts longer than a whole year.


A pouch of his own
A daddy seahorse carries the eggs in a pouch on his belly and gives birth to the babies himself.


A tiny, hungry helper
A single ladybug can eat dozens of plant-munching aphids in just one day.


Quiet flyer
An owl can swoop onto a mouse in almost total darkness without making a single sound, thanks to wings built for silent flight.


Extra beats
An octopus has three hearts, and one of them stops beating every time it swims.


Nature's own raincoat
A lotus leaf can sit in muddy pond water for months and never look dirty, because water and mud simply can't stick to it.


Sky's slow dancer
The moon seems to change shape every night, growing from a thin sliver into a full glowing circle and back again.


Thousands of miles home
Monarch butterflies fly up to 3,000 miles to a place none of them have ever been before, following a path their great-great-grandparents once flew.


Roots on the move
Mangrove trees grow roots that arch up out of the mud like a tangle of legs, letting them stand right in the salty sea.


Music made of wings
A cricket doesn't sing with its mouth at all; it makes its chirping song by rubbing a pair of special wings together.
