Although lizard, which are related to snakes, do have four legs; snakes, even though they have no legs at all, are able to move in a wide variety ways. It could even be debatable that they could actually have more mobility and be able to do additional things a four legged animal, such as the lizard, couldn't.
No, many dinosaurs walked on two legs and many others walked on fours but were capable of standing or running on two legs. Strictly two legged dinosaurs include theropods (meat eating) dinosaurs such as T-rex, Allosaurus, Spinosaurus, and Velociraptor, as well as relatively small plant eaters and omnivores such as Ornithomimus and Pachycephalosaurus. Most dinosaurs that walked on fours but stood and ran on two legs were hadrosaurs or iguanodonts, such as Edmontosaurus, Parasaurolophus, Corythosaurus, and Iguanodon.
A limbless reptile is a reptile that does not have any limbs, such as snakes. These reptiles have evolved to move by slithering or sidewinding due to the absence of limbs.
Reptiles that have limbs use them when them want to walk, climb, swim, or grasp.
A healthy lion has four (4) limbs or legs.
A bird has 4 limbs: its arms are wings and its legs are its legs.
humans have 4 limbs,
Cetaceans have only vestigial hind limbs.
Brachiosaurus means "arm lizard." This is because, unlike most dinosaurs, Brachiosaurus had longer forelimbs than hind limbs.
