Beavers have webbed hind legs that act like as a paddle when they swim through water. They have a large flat tail that helps them steer through water. Their tail is used for other things for example when they chew on trees they use their tail like a kick stand to give them support.
There is now a beaver living near my house that I see ocasionally on my daily dog walk. I have watched him from the bridge swimming in the water at a pace that would equal a normal walking speed for a human. Its Pace is the same wheather it is going up or down current, carrying/craddling branches, or even when it spots me and turns to put some distance between us. From this observation I would say they are designed more for powerful swimming than for speed.
they use four feet move one place to another
his legs lol...
They like most small mammals have four legs, they move about on these on land, and swim in water.
Yes, beavers can move their tails. They use them while swimming and can also use their tails to help build their dams.
I depens on how they feel.
the otters get full of oil and are unable to move
In water fast, on land their slow.
they use their webbed feet to push the water away, so therefore they move forward.
The plural of otter is otters.
Otters slap the water with their tails so that they can be able to move. This is their mode of swimming from one point to another.
There are sea otters and other otters. In the category of "other" otters, you can include the North American River Otter, Giant Otter of South America, Asian small clawed otters, Congo clawless otters, Capr clawless otters, Southern river otters, hairy nosed otters, spot necked otters, neo tropical long tailed otters, and others I may fail to mention.
They catch it with their claws and teeth, and move around with there very large tails, to swim very fast.
