Luo Tong said very single, it is now an egg, what is there to catch a cold or not. If she were a little snake now, I guess she would still be a little scared, but who would be afraid of an egg?

"Don't snakes hatch eggs? "Don't ordinary animals hatch eggs? Why are these eggs scattered here?"

"I don't understand, let's look it up. Sheng Qiwu sat down cross-legged, and Luo Tong simply pillowed on his lap, listening to Sheng Qiwu read those materials.

"Most snakes usually lay their eggs and leave, and they don't hatch, with the exception of a few species of snakes. ”

"In order to ensure the smooth hatching of their offspring, some snake relatives will protect their eggs, most of them are female snakes to protect their eggs, and a few male snakes will also help. ”

"Snakes that can protect eggs such as: hundred-step snake, turtle shell flower, cobra, foreign such as king cobra, krait, etc. ”

"Some snakes hatch eggs, including some larger snakes, such as pythons and Indian snakes, and they will coil around the eggs to hatch their eggs, because they are so tightly coiled that other animals can hardly see the eggs. ”

"This not only keeps the eggs warm, but also prevents predators from stealing the eggs. It is not until the snake is about to hatch that the mother snake releases herself and allows the baby snake to crawl out of the hole in the snake's eggs. Then these newborn little snakes had to be self-reliant and survive on strength. ”

Sheng Qiwu's magnetic voice came from above his ears, and in the afternoon sun, Luo Tong was a little drowsy.

"Isn't it too pitiful to have these eggs that have been discarded as soon as they are born? If we hadn't met them today, the nest would have been wiped out. ”

"That's not to say, nature is the fittest, and snakes can lay 8-15 eggs at a time, which is quite a lot. ”

Sheng Qiwu touched Luo Tong's long hair and said lightly.

"Let's talk about the habits of snakes, if the baby snake really hatches, I also know how to take care of it. ”

Luo Tong squinted, and his head rubbed against Sheng Qiwu's thigh.

"The time it takes for a snake egg to hatch varies greatly among snakes. Some are very short and only take a few days, while others are very long and can take up to 8 months. ”

"But most snakes take about two months or so. The length of incubation time is closely related to temperature and humidity, and the higher the temperature, the faster the incubation within the appropriate temperature range. ”

"In addition, it is also related to the degree of development of the egg in the female snake's body, and the higher the degree of development, the less time it takes to hatch. ”

"That is to say, this snake egg is estimated to take at least a month for me to hatch when I go back. Luo Tong lamented, a month, when it was hot.

"Pretty much, there are also those that directly give birth to small snakes, called ovoviviparous. Sheng Qiwu suddenly saw a little and raised his eyebrows.

"What is ovoviviparity, don't snakes generally lay eggs?" Luo Tong sat up and looked at Sheng Qiwu's phone.

There are two modes of reproduction in snakes: oviparous and ovoviviparous.

It is not only pit vipers that are ovoviviparous, for example, there are 55 species of sea snakes in 16 genera, which are ovoviparous snakes, completely free from dependence on land, and have difficulty moving or cannot walk on land.

Snakes of the family Snakes are oviparous, and snakes of the family Pythonidae, Blind Snake and Cobra family, some are oviparous, some are ovoviviparous.

Ovoviviparous snakes, mostly live in high mountains, trees, water, or cold regions. Its fertilized eggs grow and develop in the female snake's body, but the embryo has no direct contact with the mother, and the substances stored in the egg are its only source of nutrition, which is fundamentally different from the real viviparity.

"I understand, in fact, to put it bluntly, oviparous is to let them hatch on their own, and the survival rate is much lower. ”

"This ovoviviparity should be that after the young snake is fully developed in the mother's body, it directly breaks the shell in the body, and looks like a young snake born to a female snake. ”

Sheng Qiwu smiled: "Actually, to put it bluntly, that's the meaning, but it's not only snakes that are ovoviviparous, there are many animals that are ovoviviparous." ”

"Cone tooth sharks, star sharks, viviparous lizards, and copper dragon lizards are ovoviviparous. ”

Sheng Qiwu's fingers slid and jumped out of another page, Luo Tong was too lazy to look at it, so he simply lay on Sheng Qiwu's shoulder and listened to Sheng Qiwu read this.

"I just saw a post where a person bought a sea crucian carp, and after opening his stomach, there were 30 small crucian carp in it, which is the standard ovoviviparous. ”

"Normally, you are not allowed to catch fish in this area, right?"

"Who's to say no, it's just that not everyone in this world will think this way. ”

For the sake of small profits in front of them, many people will not have any concept of sustainable development at all.

"How are we going to hatch this egg? I don't want Dolma and the others to know, what if others are taboo about this?"

Luo Tong flattened his mouth, so this is not good in other people's homes, he is not at ease in his own home, and he can do whatever he wants.

"Isn't this egg in the sand in the first place? Let's take the sand away, and then put the egg in the sand, and it should be about the same. ”

Sheng Qiwu actually doesn't understand it very well, but that's what he said on the Internet, and it should be not much more specific.

The two of them had packed up the sand, and it was almost mid-afternoon, and herbivores began to come to the lake to drink.

Luo Tong carefully placed the sand and squatted down to the lake to wash his hands. The little fish in this lake are not afraid of people, and naughtily peck Luo Tong's fingertips,

Luo Tong quite liked this feeling, and with a slight movement of his fingers, a pearl-sized ability bead dissolved into the water.

Now it's lively, and countless small fish and shrimp are gathering towards Luo Tong. From time to time, fish will jump out of the water and make a "pop" sound.

Sheng Qiwu washed his hands not far from Luotong, looked at the emptiness in his hand, and then looked at the lively scene on Luotong's side, Sheng Qiwu was a little congested.

He's used to it, and he says he's not jealous at all when it comes to his own animal!

Seeing that there were more and more fish gatherings, Luo Tong smiled and squinted, the lake water was flowing, and the water of life that had just been here had already flowed to another place, diluted a lot.

Luo Tong condensed a few more ability beads and bounced not far away. The fish all followed the direction of the Wonder Bead, drinking the lake with infinite vitality with their mouths wide open.

These are all small fish, Luo Tong has good eyesight, and he also saw many big fish hidden under the water. They move very quickly, and a black shadow glides through them at the slightest movement.

They were so agile that they were almost as soon as the orb reached the surface of the water, and their figures appeared in that area of water.

They are very large, and they can bring out the aquatic plants floating during their movements, and the bottom of the lake is also a little muddy, Luo Tong's eyes are suddenly attracted by a big thing under the lake.
