There tail.
They can move fairly quickly for short distances.
Alligators move by bending their bodies from side to side and pushing off the ground with their legs. This motion allows them to walk on land and slide through water effectively. Despite their clumsy appearance, alligators are actually quite agile and can move quickly when needed.
Alligators typically move by crawling on their bellies using their powerful legs to push themselves forward. They are also capable of fast bursts of speed in the water by using their tail to propel them. On land, alligators can move quickly in short distances, but they are not built for sustained running.
They also move by their tails when it's in the water.
Alligators that live in fresh water will have to adapt to saltier water, or move further up rivers. Salt-water crocodiles won't be worried at all by a rise in sea levels.
legs
Water beetles move through the water by thrusting their legs back and forth. This allows them to quickly move and catch prey.
They don't 'need' to - however... the water helps to support their body. Additionally - alligators (and crocodiles) are 'ambush' predators. They cannot run very fast on land - so they lie submerged in water - waiting for prey to move within striking distance.
Yes. The only time they come on land is to get a feed, nest, or regulate their body heat. They do most of their hunting in the water.
Alligators swim by using their powerful tails to propel themselves through the water. They move in a side-to-side motion, similar to a fish, which helps them navigate and hunt for prey. Their streamlined bodies and webbed feet also contribute to their efficient swimming ability.
Alligators and crocodiles all live in the water. They are large animals, and the water helps support their weight. Also, they are predators. Both animals hide under the water and leap out to catch their prey.
alligators use their 2 legs and 4 legs, and snakes use their muscle to move side wind, serpentine, cerpintone, or straight moving.
