What are the abilities of animals?

First, the cat's eye changes three times a day: the cat's eye is not only different in the morning and evening, but also at noon, and it is different in the morning and evening. It turns out that the cat's eye sleep hole is very large, and the contraction ability of the pupil "sphincter" is also particularly strong. Cats can adjust their sleep holes well in different light. In the morning, under the medium-intensity sunlight, the pupil will form jujube pits. Under the strong sunlight at noon, the pupil can shrink as small as a line, and in the darkness at night, it can open as big as a full moon.

Second, chickens like to eat stones: chickens, like other birds, have a hard mouth called hornbill and no teeth. This kind of mouth shape makes chickens peck food well, but they can't grind food. Chickens eat stones to grind their food. The muscles of the sandbox contract strongly, and the gold and sand in the sandbox rub against the food under the crawling of the sandbox. In this way, the rice and grains eaten in the stomach are ground, and the chicken can thoroughly digest and absorb the food.

Third, the Sahara silver ant: One of the most heat-resistant insects known, the Sahara silver ant, the desert temperature is as high as 70 degrees Celsius. They can reflect the sun's radiation through their body hair and unload excess heat to keep their body temperature at the thermal limit, that is, 53.6 degrees Celsius. Silver ants are not only heat-resistant, but also crawl very fast.

4. Dolphin: Dolphins can send and receive ultrasonic waves. With this ability, they can accurately identify the location of obstacles or prey and communicate with their peers, but scientists still don't know why dolphins can distinguish the sounds reflected by different fish.

Five, chameleon: super stealth skill chameleon, good at changing the color of his body at any time with the change of the environment, in addition, it also has a pair of strange eyes, thick eyes, ring-shaped, two eyeballs protruding, left and right 180 degrees, freely rotating up and down and left and right, and the left and right eyes can move independently and uncoordinated.

Extended information ① Cats belong to cats, which are divided into domestic cats and wild cats. They are pets widely used by families all over the world. . Hunting other animals by ambush, most of them will climb trees. Cats have fat pads at the bottom of their toes to avoid making noise when walking and not scaring away mice when hunting. When walking, the claws are in a contracted state to prevent them from becoming dull and protruding when catching mice and climbing.

② Chicken is a kind of poultry. Domestic chickens originated from wild chickens, and the domestication history was at least about 4000 years. But it was not until about 1800 that chickens and eggs became mass-produced commodities. The types of chickens are turkey, black-bone chicken, pheasant and so on. Moreover, chicken is also an animal sign in the 12 zodiac.

③ Sahara silver ants feed on insects and other dead arthropods. They can survive in desert environment with surface temperature as high as 70℃, and are one of the most heat-resistant insects known. Sahara silver ants will feed in the Sahara desert at noon when the sun is strongest. The surface temperature of the desert is as high as 70 degrees Celsius. They must ensure that their body temperature is below the thermal limit, that is, 53.6 degrees Celsius.

④ Dolphins have the typical morphological characteristics of toothed whales: spindle-shaped body; A crescent-shaped breathing hole; Skull intussusception, maxillary expansion backward and overlapping frontal bone; Left cranial top asymmetry; Tapered or spiked teeth, etc.

(5) chameleon, lizard (chameleon family) reptile, native to the Old World, mainly inhabiting trees. The chameleon in the tropical rain forest of Hala Island in northeastern Madagascar is 29 mm long from the tip of the nose to the tail, and its adult trunk is only the size of a fingernail, which may be the smallest chameleon in the world so far.
