Put the baby to bed: hibernation of the red-eared turtle
In nature, there are aquatic red-eared turtles of various species and sizes. They are successfully kept in captivity in aquatorrariums. At the same time, hibernation of the red-eared turtle in the conditions of home maintenance is a certain difficulty for its owners.
Owners of turtles have logical questions related to hibernation:
How necessary is hibernation for the red-eared turtle at home in its keeping?
Why do turtles hibernate?
How to equip the hibernation of a red-eared turtle?
What effect does the hibernation of a red-eared turtle have on its reproductive functions?
What is the duration of winter turtle sleep?
Hibernation of domestic red-eared turtles
Most captive turtles do not need to be hibernated as long as they are maintained. stable temperature in the aquaterrarium. These cold-blooded animals will hibernate if there is too high or too low air temperature.
But some individuals, for example, recently caught in nature, are trying hard to get a winter, regardless of the conditions of detention, and then they need to help with this. Hibernation of red-eared turtles is especially recommended if the owner wants to receive from them next year progeny.
Hibernation of the Red-eared Turtle
The main signs of hibernation in a red-eared turtle are sharp decrease in activity and frequent yawning. The animal is slaughtered in the corner of the aquaterrarium and sits there for a long time motionless.

In this case, start preparing your pet for a long sleep. But before you start arranging a place for wintering, consult your veterinarian if this behavior is a sign of a disease of a red-eared turtle.
If the turtles are in good health, two months before hibernation increase the amount of food offered to her and the number of daily meals. Before hibernation, the red-eared turtle should be stocked with all the necessary nutrients, since during sleep it can lose up to half its former weight.
Throughout last week before hibernation, the animal can not feed in general, and one day before a long sleep, bathe the turtle several times – this will help it to completely empty the intestines.
In the room where the turtle sleeps, the air temperature should be maintained in the range from 1 to 6 ° C. Cold basement – The optimal hiding place for this cold-blooded animal. The turtle should be accustomed to such thermal conditions gradually, since a sharp drop in temperature can lead to hypothermia and even to the death of a pet.
Another important requirement is ongoing maintenance. high humidity air. A mixture of moss and leaves will be an ideal soil for wintering a red-eared turtle. Passing moisture well and not holding it, such a substrate will provide your pet with a comfortable sleep, the average duration of which is from 3 to 5 months.
Hatching a turtle
The red-eared turtle should be brought out of hibernation gradually. First you need to slightly increase the temperature in the room, and then bathe the turtle in warm water. Immediately adapt to the usual living conditions of a turtle is very difficult. Therefore, the first 2-3 days after leaving her hibernation should not be fed, very carefully moving to the usual diet for the animal.
How do red-eared turtles sleep?
Sea turtles (lat. Cheloniidae) – a family of turtles from the superfamily Chelonioidea.
The average lifespan of sea turtles is 80 years. The whole life of these reptiles takes place in water, only females creep out on land during the egg-laying period. Sexual maturity in females occurs at about 30 years. Throughout the whole year of nesting, which happens every two or four years, the female lays from four to seven clutches of 150-200 eggs. Mating turtles occurs in water, in the coastal zone, often the amount of sperm received by the female is enough for several clutches.
Sea turtles have not changed much in millions of years since they appeared on the planet. Compared to their land relatives, these turtles have some important changes that allow them to adapt to their habitat, such as, for example, legs turned into fins, a shrunken and lightened shell (a sea turtle is not able to hide its head and legs), allowing them to better maintain the body on pilaf and having better hydrodynamics, lungs, providing optimal oxygen consumption and trachea penetrated by blood vessels, allowing oxygen to be released from water.
Despite the popular belief that turtles are slow animals, this only takes place on land, where they really look awkward. However, they transform in water, becoming examples of speed and superior navigational qualities.
Scientists have not fully figured out why, but turtles have amazing navigational abilities.
: Firstly, they accurately determine the place of their birth, and return there to continue the offspring.
Secondly, sea turtles make tremendous migrations, presumably guided by the Earth’s magnetic field, which does not allow them to get lost.
The representatives of the order of turtles of sea turtles are distinguished from other reptiles by the presence of a passive defense – an armor, which is a bone-chitin shield that covers the body of turtles from the back, sides and belly. The dorsal part of the shield, called the carapace, connects to the abdominal (plastron) with either movable tendons or a strong bone jumper. Karapalax consists of bone plates of skin origin. On top of most species of turtles, the shell is covered with symmetrical horn shields. Only in one species, in a leathery turtle, the carapace is not attached to the skeleton in any way, and is built of bone plates that are connected to each other. The leathery turtle got its name precisely because of the shell – it is “leather”, that is, its cover is leather.

A leatherback turtle is the largest living tortoise: the carapace reaches 2 m in length and 600 kg in weight. The front fins, devoid of claws, reach 5 m in scope. The heart-shaped carapace has 7 longitudinal ridges on the dorsal and 5 on the ventral side.
During the year, females of leatherback turtles lay eggs 3-4 times; they go ashore only at night. They dig whole wells, the depth of which reaches 100-120 cm. Having lowered the back of the body into this well, the female lays two groups of eggs – ordinary and small (sterile). Having fallen asleep in the nest, the female densely compacts the sand with flippers. Small eggs burst at the same time, increasing the nesting space.
The most famous species of sea turtles is the green or soup sea turtle (Chelonia mydas). It is widely known in many countries, due to its delicious meat and tortoise soup, which is made from it. The shell of an adult individual of a green sea turtle can reach a length of 140 cm, and the weight of the largest specimens is more than 200 kg.
The green turtle has a low, rounded oval carapace, which is covered with shields lying nearby and not covering each other. The head is small, the eyes are large. The front flippers usually have one claw. The color of the upper side of the carapace is unstable and may be olive green, or dark brown with yellowish spots. The ventral side is white or yellowish.
At a young age, green turtles feed on different animals: crabs, sponges, jellyfish, worms, snails. But adult turtles are herbivores. They eat algae and grass, which grows on the shore and is flooded at high tide.
A big-headed sea turtle, or false carriage, is a species of sea turtles, the only representative of the genus loggerhead. In large-headed sea turtles, the shell is 70-110 cm long; their weight ranges from 70 to 200 kg (an average of 120 kg). The head is massive, covered with large shields. On the front fins there are 2 stupid claws. Top painted in brown, reddish-brown or olive color, plastron – lighter.
A big-headed turtle leads a pelagic lifestyle, feeds on bottom invertebrates, mainly mollusks and crustaceans. Very powerful jaw muscles allow the turtle to crush the thick shells and shells of marine animals.
Sea turtle bissu or real carriage from other species can be easily distinguished by two pairs of shields between the eyes. Outwardly, the bisse is similar to a green turtle, however, its body is smaller than that of a green turtle – from 60 to 90 cm. Body weight ranges from 45 to 55 kg. She has enough light, heart-shaped carapace. The back of the carapace is significantly narrowed and pointed. In young individuals, the carapace shields noticeably overlap each other, however, with age, overlaying is smoothed and subsequently disappears completely. The tail does not extend beyond the carapace. The upper jaw hangs over the lower, and is equipped with weapons – a sharp tooth. The front flippers serve as fins for this turtle, while the hind legs serve as the steering wheel. On the front flippers, as a rule, two claws.
The carriage meat is also eaten, although this is associated with risk – it can become poisonous if the turtle fed on poisonous animals. Eggs are a delicacy in many countries. Also, turtles are exterminated due to the shell – they are used to obtain the "tortoise bone". Souvenirs are made from young individuals.
Ridley or an olive turtle is very similar to a loghead, differing from it by a more rounded shell, a large number of costal shields and an olive-gray coloring of the back. The dimensions of the Ridley shell can reach 80 cm. The habitat and food preferences of these sea turtles are the same as in the previous species.
Long existed, the so-called "riddle riddle". If the masonry sites of Pacific sea riddle turtles have been known since ancient times, then in its Atlantic variety such masonry could not be found for a long time. Neither pregnant female ridea, nor small turtles were found. Turtle hunters in many regions of the Atlantic Ocean even considered the ridge to be incapable of breeding, as there was a belief that it was a hybrid animal – a cross between a loghead and a green turtle. And only in the 60s of the last century, scientists found that the Atlantic ridley lay eggs only in isolated places on the Atlantic coast of Mexico, and they lay eggs together with other species of sea turtles. And since the riddles are very similar in appearance to logheads, these nesting sites were considered to belong to loggerheads.
However, the Atlantic subspecies of riddle is most prone to population decline due to the fact that there are very few places on the planet where these sea turtles lay their eggs.
All species of sea turtles are currently strictly protected and listed in the IUCN International Red Book. In some countries, special farms have even been set up for the incubation of eggs and the rearing of juveniles. Attempts were also made to transport clutch of turtle eggs to remote islands in order to change their nesting areas. After all, it is believed that a sea turtle that has reached puberty, comes to establish a nest on the very shore where it was born. However, the abundance of all species of sea turtles is still decreasing.
