How does the crocodile swim underwater, and why did it cause netizens to laugh after it was revealed

Because the way the crocodile swims underwater is very cute, the body is upright, and the claws do not move, so after it was revealed, it caused netizens to laugh.

Crocodiles have three types of movement in the water, including landing on their hind legs and walking upright in shallow water; If the water is shallower, the crocodile will walk on all fours; But in deep water, crocodiles can't reach the ground on all fours, so they can only swim, through the swing of their body and tail, the stroke of their limbs, and some crocodiles can also swim back.

When the depth of the river is about the same as the height of the crocodile, the crocodile will often walk upright in the water on its hind legs in order to save physical strength and increase hunting opportunities and hide its body, and only a small part of the crocodile's scalp and eyes can be seen on the river surface. This way allows the crocodile to conserve its physical strength to the greatest extent, because the hind limbs support the body, so it does not need to swim to maintain the balance of the body in the water, and at the same time let its back and tail are submerged under the water, making it difficult for the prey to find out, which is conducive to a surprise attack on the prey.

Walking on all foursIf a crocodile comes to the shallow water's edge, it will walk on all fours, and the only thing that will be exposed is its head like dry bark and two small but sharp eyes. At this time, they are more able to reduce the consumption of energy, and the way they land on all fours in the water also makes it easier for them to accumulate and generate explosive power, which can be used in herbivores.

Unleash a quick and deadly assault when approaching the water's edge.

Crocodiles swim in the water when the water is deep in the river **, the hind limbs of the crocodile can only swim if they can't reach the bottom of the water, they can rely on the buoyancy of the water to float on the water, and use the swing of the body and tail, and the limbs can move forward quickly. The crocodile can see its head and back from the surface of the river as it swims, but because the crocodile skin looks rough, the crocodile swimming on the surface of the river resembles a floating old tree trunk. In addition, crocodiles can actually run forward on the river bank, and the speed of running is also very fast, but their weight is too large, and their limbs are not enough to support them for too long, and they need to stop and rest after running for thirty or forty meters.

Crocodiles walk upright in the water and swim only in an emergency, because crocodiles are ectotherms, so they are always lazy, and maintaining this position in the water can relax the body, and paddling the limbs when you need to move, so it looks like walking.

Crocodiles swim in the water. Because of its short legs, crocodiles are unable to walk upright, but float on the surface of the water and swim by themselves.

Crocodiles are reptiles, crocodiles use their limbs as power both in water and on land, and their tails are important organs for crocodiles to move forward and balance, so crocodiles do not walk upright.

Yes.

Crocodiles can swim, and this ability allows them to move in the water. When the crocodile is swimming, the swing of the limbs plays a major role. In addition, the swing of the torso also plays an auxiliary role.

Sometimes their tails also wiggle, making them move faster and swim more freely in the water. Due to the large size of the crocodile, the crocodile does not need to swim when the water is shallow, just walk forward in the water, and only need to swim when the water is deep.

Features of crocodiles.

The crocodile is a higher reptile that breathes with its lungs, its heart is divided into four chambers, and it has a bony palate on the roof of its mouth, separating the nasal cavity from the oral cavity, and its teeth are only born in the alveoli of the upper and lower jaws; The crocodile's two eyes grow on the upper end of its head, and in addition to its eyelids, it has a transparent transient membrane, a structure that allows it to adapt to the environment in the water.

Since the crocodile's nostrils are located on the back of the upper end, there are valves inside, so when it dives into the water, the valves automatically close, preventing water from flowing into the nostrils, and in its pharynx, there is also a thin, elastic membrane, when this membrane is closed, then its mouth and respiratory tract are separated.

Crocodiles can swim. The crocodile is a carnivorous oviparous vertebrate reptile and one of the most primitive animals that have survived so far, with its long, thick tail that can be used to control the direction when swimming, and can also be used as a tool for predation and a tool for defending against enemies.

It's not the hind legs, it's the tail.

Crocodiles rarely use their legs in the water. They swim with their tails. Or to be precise, it is to twist the spine from side to side to drive the body to swing in a wavy shape, so as to move forward. Just look at the way snakes swim, but the crocodiles swing less.

You can search for some crocodiles, and you can see that they swim with their legs clinging to their bodies. With the power of its tail to propel the current, crocodiles can even leap most of their bodies out of the water.

Good afternoon, the crocodile is an amphibian reptile and its own naming is wrong, and the physiological structure does not have the fish fat common to freshwater and marine fish to make buoyancy adjustments (similar to the principle of submarines, the white part of Figure 1). Without the fish fat air bag as an auxiliary, it is naturally impossible to maintain the balance of buoyancy and suspend in the middle of the current, so what you see is a cute form of shallower water and four-legged crawling with two legs - well, crocodiles, soft-shelled turtles and whales are not relatives of fish, geckos are not tigers, snails and cows, please refer to them as appropriate.

Crocodiles are reptiles. Because it is better to hunt in the water.

Because crocodiles are amphibian species, i.e. adults: aquatic or terrestrial.
