Although gorillas can walk upright on two legs, they are most commonly quadrupedal (all four). On the contrary, there are many bipeds that are definitely quadruped. For example, while humans can crawl on all fours, we are obviously bipedal and use two legs for most movements. Therefore, animals that walk on two legs are considered bipeds or bipeds.
The animals on this list of bipeds demonstrate that walking on two legs is not just a human trait. Since there are very few animals on the planet that walk on two legs, we are not too strict about this list of bipedal animals. There are surprisingly few species in the animal kingdom that walk or maneuver solely on two legs, other than birds and dinosaurs. Not surprisingly, our closest relatives, gorillas, chimpanzees, bonobos, and orangutans, can walk on two legs, although knuckle-walking is the preferred form of locomotion for our closest relatives.
When walking on the ground, chimpanzees move on all fours (walking with their knuckles) in the same way that they walk upright on two legs. Chimpanzees are closely related to humans and are among the most intelligent animal species on the planet, so it's no surprise that these great apes can also walk upright on two legs. Human beings are obviously the first species that comes to mind, but they are not the only bipedal species, i.e. the ones that basically rely on two legs to walk, in the world. Quadrupeds usually have limbs of almost the same length and walk on the same side of each leg.
Most starfish have five limbs, but they are arms, not legs, as they are not used for locomotion. Their forelimbs are not as strong and are sometimes only used for slow crawling or walking on all fours. Although spring hares also use all four limbs with slower movements, they are capable of making small bipedal leaps when approaching forward, even with their legs fully extended.
They jump long distances, but when foraging on the ground, they are more likely to use a five-foot walk, keep all four feet on the ground, and use their tail as a fifth limb to propel themselves forward. When the red kangaroo is not jumping, the kangaroo walks with its hands on the ground and its hind legs moving in front of it. Instead, kangaroos use their strong tails and forelimbs to push their hind legs off the ground and move forward as they graze.
Long hind legs prevent the kangaroo from "walking" like other mammals. Although kangaroos have four limbs, the front two are rarely used for walking. The front legs of a kangaroo are very different from the hind legs.
Rhinoceros' feet taper into round, three-toed feet, and when rhinos walk, they put more pressure on the ball of the foot, "which is strange and we don't understand it yet" - John Hutchinson, Professor of Evolutionary Biomechanics at the Royal Veterinary College and Movement Laboratory, previously reported by LiveScience. Unlike humans and birds, macropods must lower their front legs and move forward using five-legged locomotion to move slowly. People tend to use smaller muscles, such as those in their shins, and take longer strides.
Having short legs, feet out of proportion to the rest of the body and no knees, they cannot walk. The legs of the toadstools are so set back that walking becomes impractical. They are so well adapted to the water that their feet are no longer suitable for walking on land.
Napoleon (modeled on Stalin) walks on two legs, like a man, instead of the usual four. The old pig tells the other animals that a man who walks on two legs, unlike animals that walk on all fours, is their enemy. In particular, two pigs, Snowball and Napoleon, goad the other animals into taking action against Mr. Jones and taking over Manor Farm.
Since the pig can walk on two legs instead of four, it becomes the best breeder of all. As a child, a person walks on all fours ("in the morning on four legs"; morning = childhood) until he learns to walk, which he is so good at in adulthood ("on two legs in the afternoon"; in the afternoon = adulthood), until old age requires from him using a cane to support himself ("three legs in the evening", evening = old age), he eventually dies ("no legs at night", night = death).
Kangaroos are extremely athletic animals, they can jump fairly fast and far, however they cannot walk backwards. Due to the inability of flamingos to fly, ostriches rely on the strong legs and long neck of kangaroos to survive in the wild. When threatened, flamingos use their powerful legs as weapons capable of killing predators such as lions.
Gorillas, while sometimes moving with their hands on their knuckles, often walk exclusively on two legs. With the exception of birds, all groups of terrestrial vertebrates are predominantly tetrapods: mammals, reptiles and amphibians usually move on all fours.
