Species of Animals That Are Limbless
Sea lions use flippers for swimming and walking. These webbed flippers are behind their forelimbs. With less than 20,000 alive, sea lions are close to extinction.
Flippers replace walruses' legs. Flippers can walk, but not stand. Its 2,200-pound flippers propel it forward. Seals have four limb bones. Only its hands and feet are visible.
Snails have a ventral foot instead of legs. This "foot" contracts muscles and produces mucus to help the snail glide. There are 43,000 species of sea, terrestrial, and freshwater snails.
Earthworms lack legs, arms, and other limbs. They move by stretching and contracting their muscles. Microscopic hairs help worms grab surfaces.
Fish steer and stay upright using fins instead of legs. Some fish have leg-like limbs to help them move, as most of us know. Axolotls, mudfish, and garnai are examples.
An octopus's "legs" are its tentacles. Suckers are located at the end of tentacles, which are elongated arms. The longer, more powerful arms are covered by sucking suckers.
Once, whales had legs. Their forefathers lived on land with four legs. Over 50 million years ago, whales underwent a tremendous evolutionary transition Blue whales are the world's largest animal.
Clams are interesting sea creatures. This legless snail utilises its two shells to create suction, allowing it to swim.The enormous clam lives in freshwater and saltwater. Giant clams can grow to 4 feet
Slugs don't have legs and move using a muscle on their bottom. The ash-black slug is the world's largest at over 7 inches. They eat algae, fungus, and lichens in ancient woods.
