There are quite a few animals that do not have legs if you are asking in general and not just one type (eg; mammals or birds) There are snakes of course and legless lizards that pass for snakes at a glance. There are a huge number of legless animals if you start looking at sea animals so you maybe need to rephrase the question.
Many animals are limbless. Snakes, leeches, clams, sea urchins, coral, earthworms, snails and tube worms are all legless.

The number of legs an animal has certainly does affect how that animal moves. If the animal has two legs they are limited in movement to what those two legs can do.

Well, no ANIMAL has eight legs but an arachnid called SPIDER does
an animal biome is an animal with 16 legs
An animal with legs might be called a biped or a quadruped. An animal without legs can move in a two-anchor movement or in a lateral undulation movement.
In Animal Farm, the anthem is "Four legs good, two legs bad!"

I am not sure what you mean but animal which walk on their hind legs have straight legs and they are called bipedalanimals.
