Most four legged animals
Most four legged grazing animals sleep standing up including horses, giraffes, zebras, and elephants.
No. There are MANY MANY MANY others! Why, most animals are four-legged! Turtles, tigers, and zebras are, just to name a few of the thousand that exist.
A list of animals that live in saltwater can be found at most local libraries. The list can also be found in most biology books.
Most other four legged animals can move their legs independently of each other when they move, but kangaroos cannot. Also, four-legged mammals can walk backwards; kangaroos cannot take a step backwards.
most animals can. not fish or most reptiles though
Time, and careful selection of which animals that are allowed to breed. Let's say you want a long-legged dog. You start by selecting the the most long-legged males you can find, and the most long-legged females you can find, then you let them breed. Out of their offspring, you then select the most long-legged puppies, and when they're grown, you let them breed. Keep this up for several generations, and soon you have really long legged dogs. The same method is used for whatever other feature you want the dog to have.
All over the place, it's the group of animals we see most often. All 4-legged animals have backbones. All birds and snakes for instance have back bones.
Rhinos are four-legged animals. They move like most other such animals: by using the power of their legs. They are large, so movement is not easy for them, but they can move rapidly if they need to.
For camouflage of course. Deer is a good example. These four legged stupids are camouflaged in brown so predators don't eat them.
The list is ever-changing
Most animals are not endangered. To see a list of endangered animals, see the IUCN Redlist.
