Turtles, often called chelonians, are creatures that belong to the order of reptiles, like snakes, crocodiles, and lizards, and as part of their bracket, turtles are divided into two types submarine and terrestrial, and according to exploration, these creatures are known to have was on earth since the Triassic period, that is, about 220 million times agone (they participated the earth with dinosaurs). Still, we recommend you read on, If you want to learn much further about these armored creatures.
Both ocean turtles and land turtles have common rates and characteristics of the species, similar as their hard shell. This bony conformation, fused to the spinal column, is composed of plates that increase in size over the times.
Characteristics of the turtles
To harden their shell and defend themselves from bloodsuckers, turtles lounge in the sun several times a day, and their colors and patterns vary depending on the species, rubric, and climatic conditions. Also, turtles have four branches and a large, characteristic head that they can hide inside their shell when in peril.
As for the eyes, they're able of distinguishing colors but don't have a veritably accurate vision. The beak of turtles, in the case of marine species, is hard and pointed, while their frontal legs represent real flippers to propel their movement through the water.
An adult turtle can reach 30 centimeters in length, although much larger species are known. Like reptiles, turtles are ectothermic, which in other words means that they're explosively linked to the outside temperature (when downtime arrives, they generally enter a period of hibernation).
How ocean turtles breathe
Because they've a hard shell, turtles can not breathe through their caricature pen, which is why they use their abdominal muscles that pump the pharynx, veritably analogous to the movement of the diaphragm in humans.
On the other hand, marine species are known to have an adaption that allows them to retain oxygen for long ages, although they've also developed other ways. For illustration, some turtles are able of absorbing water through their anus to prize oxygen and conduct it to the lungs.
In addition, it has been shown that these creatures can also breathe through their skin, and indeed through their lingo.
How long do turtles live
The life of turtles is an aspect that has always attracted the attention of humans. There have been cases of turtles that manage to live for further than 100 times. Sea turtles, for illustration, can live between 150 and 200 times, although other estimates place this period between 80 and 100 times.
Origin and expansion
So far, it has been determined that turtles have been living on earth for 280 million years, specifically since the Triassic period. Their origin is established from the Captorhinus, a species of neolithic reptile that didn't exceed 60 cm in length.
From its elaboration, it gave way to the Odontochelys, a species honored as the first turtle on our earth. In this sense, turtles are much aged than snakes or lizards. Also, it's known that turtles were firstly terrestrial creatures. Fifty million times latterly, part of this species came entirely submarine.
Where turtles live
Turtles prefer sticky and breezy surroundings. During the downtime, it's common for them to hibernate to cover themselves from high temperatures. The presence of water in the niche of these creatures is necessary, not only for drinking but also for bathing and keeping their bodies constantly doused.
The rigidity of turtles to survive in a wide variety of surroundings is well known. Land turtles inhabit timbers, comeuppance, and rainforests, and over the times have managed to manage with extreme conditions similar as failure and heat. Sea turtles, on the other hand, are common in gutters, lakes, and swell.
Similar has been their position of adaption that they only pierce land to lay their eggs. Sea turtles prefer ocean basins and tropical strands. They're frequently suitable to navigate long distances in hunt of food.
Therefore, some turtle populations live between Japan and California, although there's also a wide distribution from the Chilean seacoast to Alaska.
