The snake nest. How do snail eggs live and lay?

Science knows about three thousand species of snakes. They live in water, forests, savannahs, deserts and mountains. How do snakes lay their eggs and multiply? Do they build nests? Let's find out how the life of snakes goes in nature.

Snakes

Snakes represent a suborder class of reptiles. Together with crocodiles, turtles, lizards, they are referred to reptiles. The closest to external and internal signs, they are to the lizards. It is assumed that it was from them that snakes occurred about 120 million years ago in the Cretaceous.

Their body is elongated and devoid of paired extremities, it is covered on the outside with scales. The skeleton consists of a skull and a spine with ribs. Coloring reptiles - the most diverse: bright and dull, with a pattern and without. Within one species, it varies depending on the sex of the individual and the time of year. Many species are poisonous.

Snakes live on almost all continents of the Earth. They are not present in Antarctica, Ireland, New Zealand and on some islands of Oceania. The most pleasant for them are the hot tropical regions. They mostly live on the surface of the earth, but some species have mastered the water and underground space.

Lifestyle

Absolutely all kinds of snakes are predators. The structure of their ribs and jaws allows swallowing large prey completely. Some of them are picky and eat only a certain kind of organisms. Without food, snakes can survive for about two months.

They are equipped with a good scent, many species have excellent eyesight, thermal and vibrational sensitivity is developed, which makes them perfectly visible day and night, tracking production during its movement.

These are ideal hunters. Quietly and unobtrusively they disguise themselves, looking for a potential victim. Then rush at it with unimaginable speed. Boas first choke prey, other species begin to eat it alive. Poisonous snakes bite and leave the victim, waiting for the moment when the poison paralyzes it.

What does the snake's nest look like?

Closest to reptiles is a class of birds. Therefore, it is not surprising that both of them multiply, laying eggs. True, some snakes are viviparous (vipers, boas, etc.). The mating period of reptiles begins immediately after hibernation.

Place for masonry, they do not do it themselves. Nest snake - this is usually an empty hollow tree or an abandoned burrow of other animals. They can also place eggs under logs, fallen branches, stones, burying masonry in leaves.

Most of them do not protect offspring in any way. After the snake's nest is built, the female leaves the masonry for good. Some species still care. For example, the python wraps the eggs with a ring, guarding them and at the same time warming them with the help of a pulsation of muscles.

Snakes multiply several times a season. In particularly favorable conditions for them, they are fertile all year round. The average masonry is ten eggs, but not all young individuals live to their maturity.

Nest of the royal cobra

Snakes who build nests themselves, not very much. One of them is a Hamadriad, or a royal cobra. It lives in the tropical regions of South-East and South Asia, where heavy precipitation falls. To nest is not flooded, it is built on a small ledge or elevation.

Eggs are deposited only a month after mating. One individual at a time produces up to forty eggs. Small cobras appear after a hundred days. At this time the female constantly watches them, sometimes the father also participates in the process.

The snake nest is more than 1 m in diameter. To build it, the female collects or breaks branches, rakes the leaves with the tail. The nest has two tiers. On the bottom there is a masonry, which is sprinkled with branches and foliage. Above is the female. Periodically, it adds new foliage to maintain the desired temperature.

Royal cobras are the largest of all known venomous snakes. At the time of "incubation" they are extremely dangerous. They track down everyone who is near the nest, and can attack without warning.
