Did you know that the different types

of creatures on this earth are either

warm blooded or cold blooded?

Warm blooded means that the animal keeps

its body temperature the same no matter

what the temperature outside is.

Cold blooded means that the animal gets

hotter or colder based on the temperature outside.

Mammals and birds are warm blooded.

Whether it's sunny and hot or ice cold outside,

the temperature inside their bodies stays the same.

The food they eat created energy that warms their bodies up

when it's cold, and when it's hot they cool off

by sweating, panting or shedding.

Reptiles, fish, and amphibians are cold blooded.

When the sun is out, their bodies soak up that heat

and get warmer.

And when the sun goes down, their bodies cool off

just like the temperature outside.

They warm themselves up when it gets too cold outside

by shivering, migrating to warmer waters, or hibernating.

Warm blooded and cold blooded animals have

lots of other things in common,

but how they manage their body temperatures

will always be a little different.

Thanks for watching.
