Highlight what are the reptile characteristics The most relevant is a beautiful tour that will allow you to discover the wonderful world of these animals that, despite being so exotic and terrifying, teach a lot about them and why they become amazing.
What are reptiles?
Reptiles are quadrupedal, vertebrate, rampant, layered creatures that began 319 million years earlier. They are a widely improved and abundant variety in the world, and were previously the dominant lifestyle, in the dinosaur periods.
They are identified in development with creatures of land, water and winged animals. Reptiles exist today alongside man and hold a prominent place in his creative mind, in any case, turning out to be companion creatures.
Four huge circles of animals are suggested as reptiles: the impressive turtles - testudines, reptiles and the amazing snakes - Squamata, alligators and crocodiles - Crocodilians and tuataras -rhynchocephalia.
How did they evolve?
They start from the Late Carboniferous – Pennsylvanian time period from the advancement of tetrapods, which links them to creatures of land and water. However, reptiles differentiated abundantly during the Mesozoic, offering to ascend to different parts of dinosaurs, now extinct.
Today's reptiles, as has been said, are made up of the most incredible turtles -chelonians, reptiles – iguanas, chameleons, reptiles, the terrifying snakes – snakes, creatures of land and water, crocodiles, gharials and alligators, finally tuataras.
Characteristics of reptiles in broad terms
Reptiles are a different creature, in it we discover lizards, snakes, turtles and crocodiles. These creatures have their habitat on land and water, regardless of whether they are sweet or pungent due to salt.
We can discover reptiles in tropical mountains, deserts, prairies, much colder regions of the planet. The attributes of the reptiles have authorized them to repopulate a great variety of environments.
Classification
Reptiles are vertebrate creatures that were derived from a circle of very old fossil creatures called land and water reptilomorphs called diadectomorphs. These first reptiles began during the Carboniferous time period, when there was a wide variety of nutrients.
These animals from which the existing reptiles developed are arranged in three groups, depending on the proximity of short openings, they have spaces in the skull to decrease their weight:
- The amazing Synapsids: It is a class of lizards that closely resemble mammals and that formed them. They made some individual memory lanterns.
- There are also the Testudineans or anapsids: Where the most impressive turtle creations come from, they have no transient windows.
- Diapsids are isolated in two groups: The amazing archosauriomorphs, incorporating all species of dinosaurs, which offered ascendancy to winged creatures and crocodiles; and lepidosauriomorphs, which gave life to reptiles, snakes and others.
Thermal control
The huge diverse array of reptiles share numerous organic attributes for all intents and purposes, the main one being that they cannot control their body temperature.
This implies that they are ectothermic, relying on the earth and their own behavior to keep the body at its ideal temperature. That is the reason why it is expected to see them despite everything, bask in the sun or avoid it indoors, how the Galapagos tortoises.
Food
Among the reptile characteristics it is found that they can be herbivores or meat-eating creatures and have a direct example related to the stomach. Their digestion is much slower than that of mammalian animals, so they embrace extended resting spaces and remain alive for a long time in a great feast.
They are for the most part competent predators, invested with savagery, sharp teeth, and regularly poisonous organs that transform their bite into a deadly assault. This is common in the terrible Komodo dragons and snakes, whose means of development has led them to adjust compound organs to make them into a weapon.
Herbivores, meanwhile, use shakes and stones – gastroliths to help mash vegetables, as they fall short of a perfect biting device. For marine reptiles, moreover, this stony substance is completed as a counterweight for immersion.
Habitat
Reptiles favor warm biological systems as they depend on it to maintain their temperature. Other things being equal, they populate virtually every area of the landmass, adjusted to terrestrial, maritime, separate, subterranean, or arboreal life.
Monstrous relocations are made in numerous species, over miles, of course, to continue production or romance. Such is the situation of sea turtles, as well as amphibian characteristics.
Types of reptiles and examples
In the previous segment, there was the option of knowing the disposition of the reptiles that the current ones started. In this way, three meetings of reptiles are to be known:
crocodilians
The Crocodilians are an order of enormous ruthless reptiles that navigate the sea, among them, crocodiles, caimans, the terrible alligators, the terrifying alligators and these are probably the most commissioned models:
- The impressive American Crocodile – Crocodylus acutus
- The great Mexican Crocodile – Crocodylus moreletii
- American alligator – Alligator mississippiensis
- The curious Spectacled Caiman – Caimán crocodilus
- Terrifying as its name the black Yacaré – Caimán yacaré
Black alligator – Alligator caiman
Squamous or Squamata
It is possible to visualize in this classification the fearsome snakes, the attractive lizards, the most charming iguanas and the dangerous blind shingles, such as:
- The terrifying Komodo Dragon – Varanus komodoensis
- The beautiful Marine Iguana – Amblyrhynchus cristatus
- Incredible as charming the Green Iguana – Iguana iguana
- Very rare and imperious the common gecko – Tarentola mauritanica
- Impressive as its name the green tree python – Morelia viridis
- Dangerous the reckless Blind Shingles – Blanus cinereus
- Incredible for its shapes the Yemen Chameleon – Chamaeleo calyptratus
- Interestingly the Australian Thorny Devil – Moloch horridus
- Ocellated Lizard – Lacerta lepida
- Desert Iguana – Dipsosaurus dorsalis
Desert Iguana – Dipsosaurus dorsalis
turtles
Among them you can distinguish the most distinguished reptiles that make up the fantastic turtles, both terrestrial and maritime:
- The majestic Black-backed Tortoise -Testudo graeca
- Beautiful as its cover the Russian Tortoise – Testudo horsfieldii
- Charming for its striking color the Green Turtle – Chelonia mydas
- Interestingly the loggerhead sea turtle – Caretta caretta
- The beautiful leatherback sea turtle – Dermochelys coriacea
- Snapping Turtle – Chelydra serpentina
Snapping Turtle – Chelydra serpentina
How do they reproduce?
The reptiles are oviparous, prepared inside the female, the eggs have a resistant capsule that, when presented to the air, continuously solidifies, keeping the incipient organism secured until it hatches.
New ones emerge from them, from that moment with the total morphology of adults, there is almost zero protection with respect to their elders, depending on the species, for this reason the importance of sexual reproduction in animals.
After inspecting some cases, we proceed with the reptile Characteristics, they are oviparous creatures, that is, they lay eggs, although some are ovoviviparous, similar to specific snakes, producing an entire offspring.
The preparation to fertilize is consistent inside, the capsule of the eggs can be hard or material. In females, the ovaries are immobilized in the stomach cavity and have the Müllerian canal that secretes the egg capsule.
How is your Skin?
One of the most exceptional attributes among the characteristics of reptiles is that in them there are no mucous organs in the skin to guarantee it, only epidermal scales. Which can be displayed in various ways: side by side, covering.
The shells leave a portable region between them, called a support, to develop movement. Beneath the epidermal scales they discover bony scales called osteoderms, their ability to make the skin become more and more vigorous.
How is your breathing?
Unlike land and water creatures with moist skin, reptiles rely on their lung limit for gas passage. Some are anatomically arranged to inhale through the nostrils, in any case, when the mouth is open or busy with different tasks.
Types of systems they own
Within the characteristics of the most relevant reptiles, it can be considered that there are also a series of very important frameworks in the life of these animals:
Respiratory system
In the case of showing the attributes of land and water creatures, it can be seen that the breath passes through the skin and lungs, they are not properly distributed, that is, they do not have numerous repercussions for the transit of gases.
In reptiles, this segment expands, causing them to generate a specific shock when breathing, particularly reptiles and crocodiles. In the same way, the lungs are traversed by a pipe called the mesobronchus that has implications where the transit of gases occurs.
Circulatory
Unlike warm-blooded animals or flying creatures, the nucleus of reptiles has only one ventricle, which in many species begins to segment, although only in crocodilians is it fully divided.
In Crocodilians, the heart has a structure called the Paniza opening that connects the left piece of the heart with the right. This structure serves to reuse blood when the creature is submerged in water and cannot or does not want to come out to relax.
Digestive
The arrangement of reptiles with the stomach is the same as that of well-evolved creatures. This starts at the mouth, which could possibly have teeth, continues with the throat, the stomach, the small digestive frame, extremely short in predatory reptiles, and the internal organ that discharges into the cloaca.
Reptiles don't bite into food, so meat-eaters produce enough stomach acid to further absorption, and this process can take a few days. What reptile characteristics, it can be said that some swallow stones of different sizes that make them crush food at stomach level.
Some have harmful teeth, the terrible snakes and 2 types of gila reptiles of the Helodermatid family - in Mexico. Both species are harmful, some salivary organs are changed and are called Durvernoy's organs. They have a couple of grooves to emit a harmful substance that paralyzes the prey.
In reckless snakes there are several types of teeth:
- They have Proto Glyphs Teeth: Which are in the front and have a trench.
- The Glyph Teeth: Those that are distinguished without a channel.
- They also have the terrifying opisthoglyphic teeth: They are those that are found in the back of the mouth, with a channel through which the toxin is presented when injected.
- And on the other hand, the amazing solenoglyphic Teeth: Only vipers possess them, it is an interior pipe. The teeth can shake to and fro and are progressively damaging.
solenoglyphic teeth
Nervous
Although anatomically the sensory system of reptiles has parts indistinguishable from the sensory system of warm-blooded animals, it is substantially cruder, the reptilian brain has no convolutions, which are the common punctuations of minds and serve to cement the unexpanded girdle the size or corpulence of the brain.
The cerebellum, responsible for coordination and equalization, is not two-sided and is highly evolved, as are the optic projections. Certain reptiles have a third eye, which is a receptor for light, and links to the pineal organ, located in the brain.
Excretory
Reptiles, just like a number of other creatures, have two kidneys that make urine and a bladder that stores it before it's expelled down the drain.
However, there are reptiles that do not have a bladder and eliminate urine through the drain instead of saving it, it is a curiosity of the reptiles that some know.
On the other hand, terrestrials, with less access to water, change the salts with the smell of uric corrosion that should not weaken, so the urine of terrestrial reptiles is much thicker, becoming paler and whiter.
Other characteristics of reptiles
In the analyzed areas, the characteristics of the reptiles with respect to their life systems, food and breath have been mentioned. However, there are numerous dissimilar highlights for all reptiles, and these are the most curious:
They have short or absent limbs
Most reptiles have extremely short appendages. Certain reptiles, similar to snakes, do not have legs. They are creatures that move extremely close to the ground. The oceanic do not have long appendages.
They are ectothermic animals
Reptiles are ectothermic creatures, this implies that they are not able to direct their internal heat level without anyone else and depend on the temperature of the earth. Ectothermy is connected to specific practices.
Vomeronasal or Jacobson organ of reptiles
This organ is used to distinguish certain mixtures, generally pheromones. Likewise, through salivation, taste and smell can be known, that is, the effect of taste and smell that are experienced by the mouth.
Heat-receiving nostrils
Some reptiles capture small temperature contrasts, distinguishing up to a difference of 0.03 ºC. These holes are located on the face, range from one and two games or even up to 13 games of holes.
