Are snakes mammals Are snakes oviparous or mammals

Mammals are homeothermic, vertebrates with hair on their bodies, mostly viviparous, and feed their offspring through mammary glands.

So ......The snake is certainly not pulling.

Snakes do not belong to the category of mammals.

But snakes have oviparous and ovoviviparous.

Ovoviviparity is also a type of oviparity, which has nothing to do with viviparity, except that the incubation process of ovoviviparous snake eggs is carried out in the body of the mother snake. This is the result of the long-term adaptation of the animal, and it is the reproduction mode formed by the long-term adaptation of the animal to the adverse environment, so that the mother plays a protective and incubating role in the embryo.

Snakes are phylum Chordates.

A class of animals under the class Reptiles. The body is elongated, divided into three parts: head, trunk and tail, no limbs or claw-like hind limbs on both sides of the cloaca of lower snakes, the body is covered with scales, the head shape is different, the nostrils are located on the snout side, but the lifelong marine species of the sea snake family live on the back of the snout.

Protective transparency** outside the eyeball, round, vertically oval or horizontally oval, no active eyelids, almost spherical lenses, elongated and bifurcated tongue, premaxilla, maxilla.

The palatal bones, wing bones, and tooth bones are epiphytically curved with the cusps of teeth, but the size, number, and structure of the teeth vary from species to species, with the tail significantly shorter than the head length.

Snakes are not mammals, snakes belong to reptiles.

Reptiles are ectotherms, dry and glandless, do not excrete uric acid, etc., which are characteristics of evolutionarily relatively primitive reptiles. And mammals are more evolutionarily complex higher organisms, homeothermic, viviparous, mammal, developed nerve center system, ** glands, excretion of urea, etc., these are the evolution of mammals relative to reptiles, so snakes are not mammals.

Extended information: The reason why the snake can crawl is because it has a special way of moving, when crawling, the snake body makes a horizontal wavy bend on the ground, so that the back of the bend exerts force on the rough ground, and the reaction force of the ground pushes the snake body forward, if the snake is placed on a smooth glass plate, then it is difficult to move an inch, and it cannot crawl in this way, of course, there is no need to worry about the snake, because in nature there will be no smooth ground like glass.

Snakes have a habit of changing their skin, which is generally referred to as molting. In the molting habit of snakes, the skin of the snake is layered on top of each other. Snake scales are closely connected, the old and new skins are tightly connected, and the process of molting snakes is like shedding socks from the soles of the feet.

The skin of snakes becomes dull and dry during molting, and their eyes become cloudy or blue. Moisture is generated on the inside of the old leather, which separates the old and new leather. After a few days, the snake's eyes were clear again, and the snake's skin had been removed.
