Can you tell us about the manatees, please?
Sure. We're trying to save them.
Why? Are they endangered?
Yes. There used to be a lot of manatees, but now there aren't very many of them.
Do you know how many there are?
At this point, there are only about 2, 500 in the U.S.
In 1927, it was discovered that they were endangered.
Since then, the government has passed laws to protect them.
Where do they live?
Their favorite habitat is the water under the trees in mangrove swamps.
And why are they endangered?
Some of the swamps have become polluted.
Also, there sometimes isn't enough food for all of them.
As you can see, they're large.
The average manatee is about ten feet long and weighs about 1, 000 pounds.
They need about 100 pounds of aquatic feed a day.
Oh, that's underwater plants and vegetation.
That's what they eat.
