You know several extremely rare and exotic creatures it

Darwin, a famous British biologist, advocated the origin of species. In the competition for survival in nature, to adapt to a specific environment, organisms underwent a series of natural selection and gradually evolved from primitive forms. This claim may indeed have his truth in front of some strange creatures. Today, Tao Tao will take you to see the strange creatures with musical notes.

Fishing spiders are semi-aquatic creatures that live in freshwater. They mainly prey on insects such as planktonic insects. But sometimes small fish and even frogs are in their pockets. Unlike water, spiders live underwater for a long time. Fishing spiders generally live on the surface of the water because the surface tension of the water allows them to walk on the surface, and its hydrophobic hairs make the body of the fishing spider look like it is coated with silver when it enters the water. This is because its hairs trap air and help it breathe underwater, thus facilitating predation. It can breathe underwater for more than 30 minutes, and the key to feeding lies in its forelimbs, which can feel vibrations. A fishing spider standing on the surface of the water can not only use its forelimbs to distinguish non-animals such as fallen leaves or vibrations from creatures in the water, but it can also tell the distance of its prey and wait for the opportunity to silently await its arrival. When the time comes, the fishing spider places its body on the surface of the water and its legs act like the claws of a crane, grabbing the prey together. After firmly grasping the prey, the fishing spider will inject the venom into the prey, which will slowly liquefy the prey's body and eventually become the food in the fishing spider's mouth.

In a situation of insufficient strength, bluffing may be the best response. This caterpillar makes a perfect demonstration. The larvae of this family of earth dollar worms will mimic a snake when it senses danger. It puffs up its head by drawing air from its pores, and with its original markings, it looks like a living, fierce snake. It is not easy for the caterpillar to do this trick. It has to hang upside down on the leaves to reveal the inside of its body and then achieve an intimidating effect by inhaling and expanding. At first glance, it does seem to fall for the trick, and it is no wonder that it can scare away many enemies.

The crocodile eel, also known as the sharp-snouted fish, alligator, and big-mouthed eel, could not be named without its trademark crocodile-like mouth and two rows of razor-sharp teeth. The crocodile eel is the largest of the eel family and can grow up to three meters in length and weigh up to 159 kilograms. This fish is often considered a primitive fish and a living fossil, with its fossils dating back even 100 million years to the Cretaceous period. Morphologically, they retain many of the characteristics of their fish ancestors, such as a shark-like spiral gut, and the ability to breathe underwater. They have a fish-like appearance and hard olive-brown scales, but the interior of their bodies is white, which facilitates invisibility in brown rivers. For crocodile eels' prey, crocodile eels will sneakily follow and attack. The usual prey are fish-eating animals that inhabit the water's edge, mainly waterfowl and mammals that float on the surface. They look fierce, but they do not tend to attack humans.

The honey bear is a mammal that lives in the rainforests of South America. It looks like a group of monkeys. But he's not. It's a family of bear cheer. The honey bear has a fifth hand that is longer than his head and body, and that is his tail. He is better at manipulating his tail than any other animal. Baby bears spend most of their time in the trees. Although their powerful tails are not used to catch food, they play an important role in hanging and climbing trees. Honey bears have golden-brown fur, and a tongue of about 13 cm, and often eat nectar from flowers. Hence the name. In the process of collecting honey, it encounters pollen, and it naturally becomes a competent pollen disperser. They also eat fruits and sometimes insects, such as ants. The honey bear is very rare because it is nocturnal and is not usually found during the day. However, this year, many people have started to breed honey bears and this rare animal is slowly starting to enter human life.

The elephant shrew is an insectivorous mammal that lives in Africa. It looks like a relative of a mouse or shrew, but in fact, researchers have found that it is closer to an elephant than a mouse. The elephant shrew is named for its elephant trunk and tail, which is very similar to that of a mouse. Their main diet is worms, centipedes, spiders, and other insects. Like anteaters, they can twist their trunks to find food and then use their tongues to pop it into their mouths. Elephant shrews are very cautious and good at hiding. They will run away as soon as they are harassed. They are very fast runners. They are one of the fastest small mammals in the world, reaching speeds of up to 28 km/h. They are 10-30 cm in size and have long legs. Scientists discovered them in 1970 and it will be 50 years before they meet again in 2020. It can be said that they are extremely rare animals in the world.
