So predators on land can not access them
eazy!
You have to go around them using pipe tunnels that you can find underwater
The Atlantis
Their eye lids protects their eyes. Beavers eyes let them to see both underwater and on land.
When they go underwater, their ears and mouth seal so they don't get water in them, this helps them stay underwater for a solid 15 minutes.
yes so they can see
They do, although I don't have the download link.
Beavers can swim 5 to 9 miles per hour. They move a lot slower on land. They can also stay underwater for 10 to 15 minutes.
underground/underwater tunnels, "mules", body stuffing, and kids
A dam is just like a small lake, or pond. Beavers gets in and out by going up the bank/beach. If you're actually asking about their "lodge", the big pile of branches that they live in - There's a living space that's above water level, and then tunnels that open up underneath the surface of the water. These tunnels are the way in and out of the lodge.
A beaver does not breathe underwater, they can hold their breath for a long time.
Sounds like beavers.
