Why do sea turtles travel long distances to give birth to baby turtles?

They have to find a suitable environment, because the specific heat of the sea water is relatively high, which causes the sea water temperature to be low, and they cannot help the turtle to hatch the eggs (the turtle is a reptile, and its own body temperature cannot match the temperature of the egg) Therefore, the turtle will choose the beach as a place to lay eggs, where the sand can reach a relatively high temperature under the sun, so that the fertilized eggs in the turtle eggs can continue to grow.

Every year in May and August, it is the breeding season of sea turtles, they travel thousands of miles to return to their native land, climb to the shore, use their hind limbs very dexterously to dig egg pits, lay eggs in the pits, and then bury them with sand. Turtles lay 50 200 eggs at a time, and the eggs are the size and shape of table tennis balls. Turtle eggs buried in sand pits also face a variety of threats – devouring by predators, inundation and natural erosion, and some not being able to hatch.

After an incubation period of about two months, the baby turtles break their eggshells and climb to the ground after a few days of hard work. Usually the baby turtles crawl out of the sand nest at night, and under the guidance of the moonlight and starlight reflected in the sea, the baby turtles instinctively crawl towards the sea. Countless baby turtles are on the sand, devoured by birds, crabs and other animals.

Some of the surviving turtles eventually crawl into the sea, but what will be their fate in the future? Where are they going? When will they come back like their elders to continue their mission of reproduction?

All this is hidden deep in the ocean of Haosen, and it is unknown.

In order to find a suitable environment for the hatching of baby turtles.

In order to give the baby turtles a good environment to live in.

The turtle lives in the sea, it has no gills and can only breathe air. If a turtle lays its eggs in the seawater, the newly hatched baby turtle will drown. The fundamental reason why turtles do not lay eggs in the sea is that turtle eggs require a lot of air during the hatching process; The temperature of the sea water is relatively low, and it is not enough to meet the requirements of incubation.

So, every May-July, flocks of sea turtles climb ashore and dig a pit about 30 centimeters in circumference and 50 centimeters deep on the beach with their hind limbs, laying about 100-200 eggs at a time, and then filling the pit. After about 60 days, the baby turtles hatched, and they crawled out of the sand pit and scrambled towards the sea. It turns out that sea turtles go to land to lay eggs so that baby turtles can come into the world smoothly and reproduce better.

The sand on the beach can reach a relatively high temperature under the sun, which can allow the fertilized eggs inside the turtle eggs to continue to grow. When incubating, the eggs need temperature, humidity and protection.

Because the beach conditions are more suitable for hatching, the temperature of the beach is relatively high, and it is easy to cover the turtle eggs.

The beach can bask in the sun, and all animals are born at relatively high temperatures before they can hatch successfully.

The beach is hot and can be fixed in a fixed position, so if it is in the sea, it will be washed away by the water or eaten by other animals.

The sand on the beach is relatively hot, and it is easy to form a natural barrier.

The birthplace is more suitable for hatching, I am afraid that the outside environment will not be able to adapt to it.

The place of birth is suitable for hatching and is protected from outside interference.

The temperature is moderate on the beach, and in the sea it will be targeted by other animals.

The beach is warm and safe. It is also good for baby turtles to return home.

Because they feel that the beach is safer than the sea.

It's suitable for hatching, but it's just that the place is suitable, and there is no other reason.

Because they think the beach is better for them to hatch.

This is a good place for them to hatch eggs, and they can also go home and have a look.

Summary. Hello dear, turtles can crawl. Sea turtles are a collective term for the sea turtles of the family Turtles and the family Leatherback turtles.

In order to adapt to aquatic life, the body is relatively flat, the limbs are fin-shaped, and the long forelimbs are like oars, which is very suitable for swimming freely in the water. With the exception of its head, limbs, and tail, it is covered in a hard shell.

Hello dear, turtles can crawl. Sea turtles are a collective term for the sea turtles of the family Turtles and the family Leatherback turtles. In order to adapt to aquatic life, the body is relatively flat, the sedan chair posture is relatively flat, the limbs are fin-shaped, and the long forelimbs are closed like oars, which is very suitable for swimming freely in the water.

With the exception of its head, limbs, and tail, it is covered in a hard shell.

Sea turtles are mainly found in the Pacific, Atlantic and Indian oceans. Most sea turtles live in places such as shallower coastal waters, bays, corals, and estuaries, which flow into the sea. In addition to laying eggs and basking in the sun, sea turtles usually have little to come ashore.

The vast majority of turtles have a gentle temperament, and when they encounter an enemy, they will only shrink their heads and refrain from attacking them. Nuclear Tung Tree.

Generally, the beach will be dark, and the sea surface will be reflective, and the baby turtle will crawl in the direction of the light to reach the sea.

Sea turtle (scientific name: chelonioidea) is a general term for turtles of the turtle family. It is widely distributed in the Atlantic, Pacific and Indian oceans.

Chinese sea turtles are found in the coastal waters of the Beibu Gulf from Shandong in the north to the south of the Beibu Gulf. It can be more than 1 meter long and has a lifespan of about 150 years. There is a pair of forehead scales on the top of the head.

The limbs are like oars, the forelimbs are longer than the hind limbs, and each has a claw on the inside. The head, neck, and limbs cannot be retracted into the nail. Feeds mainly on seaweed.

It lives in the Atlantic, Pacific, and Indian oceans, and goes to land to lay eggs and hatch larvae. It is a national second-class protected animal. Sea turtles are adapted to live in the water, and their limbs become fin-shaped, which is good for swimming.

They generally only go ashore from the water during the breeding season. Female turtles lay their eggs in burrows dug in the sand.

Sea turtles, which are considered conservation animals, live in the sea for a long time, but they often climb ashore, especially in June and July, when they want to lay eggs, they will take advantage of the darkness to climb onto the beach and dig holes with their hind limbs.

Sixty or seventy eggs lay in a hole in the sand, and finally they are covered with fine sand and then crawl back into the sea.

It has been found that when turtles lay eggs, tears flow from their eyes. Some people think that it is because the egg-laying process is so painful that the turtles cry; It is also said that sea turtles leave the sea and go to land, so as to prevent their eyes from drying out or sand particles from entering. So far, however, the answer has not been determined.

A zoologist once conducted an experiment on a sea turtle, he poured half the weight of the turtle's body weight into the turtle's stomach, and after three or four hours, the turtle absorbed more than 90% of the salt in its body, and all of it flowed out of the body with its tears. The turtle's vital organ, which excretes excess salt, is a gland hidden behind its eye sockets, known to experts as salt glands. This also explains why sea turtles can swallow salty marine plants and drink seawater to quench their thirst.

Because eggs cannot be laid in the sea.

Turtles are not visible when they come out of their shells, because they hatch in the sand.

Newborn baby turtles climb into the sea on their own, and at night they can distinguish the direction of the sea by the reflection of the sea, and during the day because it is difficult to distinguish, some of the baby turtles will get lost, and some will be eaten by birds or other animals.

Most turtles only live for one day and are born to crawl into the sea, where they can be eaten on the way.
