What animal is the only one with two legs and can’t walk out of all the animals? It could be a cat, or a dog. Cats and dogs are the only non-avian animals with two feet, although there are cases where an injured animal is able to walk on two legs. Non-avian birds rarely walk on two feet, which is unusual for non-avian birds. In fact, a giraffe has three feet, despite the name. This was 200 million years ago before Tyrannosaurus, and 290 million before the first hominids.
Aside from a cat, a giraffe can be found on all continents. A baby giraffe’s first wobbly steps come at 30 days old. This fact is crucial to understanding why the giraffe is the king of bipeds. It is also important to know that the heaviest parrot is a kakapo, also known as owl parrot. Iron horses and bats are two exceptions to this rule.
Kangaroos, large hopping mammals that hail from Australia, are large. They use their pouches to carry offspring. They cannot walk backwards but can jump with saltation movements. This requires two large feet to push off simultaneously. These animals use their tails for balance. Their two-footed feet, big tail, and robust legs allow them to move easily and quickly across the ground.
Bipedal animals include the Japanese macaque and some other animals. The latter has two wings. The Japanese macaque, for example, sometimes walks bipedally and hops in front of the zoo. A few ground birds, like the Gentoo walk bipedally. The list goes on. The guineapig is bipedal but not bipedal.
