Characteristics of reptiles
What are reptiles:
Reptiles are a diverse group of
vertebrates that include snakes, lizards, crocodiles, turtles, worm-like
lizards, and caiman.
They
live in deserts, forests, freshwater wetlands and the open ocean. In fact, reptiles are cold-blooded and
therefore require less food than birds and mammals.
It is
a dominant animal in desert environments.

Characteristics and classification of reptiles
Several characteristics make reptiles
animals
Able to live on land, it is equipped
with lungs that allow it to breathe and dry skin covered with scales that
protect it from water loss through evaporation.
As they grow, these scales grow, renew and
scatter, giving way to the formation of new scales: this is what is called the
scion.
Reptiles cannot adjust their internal
temperature on their own.
They
must be exposed to the sun to warm their bodies or hide to reduce their
temperature.
They are eggs, meaning they give
birth to their young using eggs, but some of them, such as the glass snake (the
fad) and the brood snake, are sarolod, meaning that they give birth to complete
young, but they arose in their guts within an egg. Reptiles today are classified into three
categories: Turtle category

the thoracic, which covers the chest and abdomen. The cochlea gets bigger as it gets bigger
Animal
The turtle uses this shell as a
protection and refuge because most turtles can insert their head, figure, and
tail into it.

She walks on the ground on all four legs, but spends a large portion of
her time in the water.
She

: Information about crocodiles
Crocodiles are carnivorous animals
that hunt all kinds of animals. They
settle under the water without moving, taking the position of a lurker: they
only emerge from the water with their noses and eyes standing at the top of
their heads.
They can
hunt animals the size of a zebra on the water hole
The
twenty-two species of crocodiles are classified into three categories: the true
crocodile category, the alligator and caiman category, and the gharial category
(Indian crocodile), and this category is represented by one species,
True crocodiles are known for their long lines and the coordination of their visible teeth when the animal's mouth is

As
for alligators and secretions, only the upper row of their teeth appears when

What are the characteristics of reptiles ?
Reptiles share many characteristics, the most important of which are:
Reptiles are covered in scales
One of the main distinguishing factors between reptiles and animal classes
The other is the presence of metrics.
The scales that cover the reptile's body
consist of keratin, which consists of the epidermis, unlike fish scales, which
consist of the dermis.
The
scales on reptiles vary in shape, size, and color. Its main function is to protect the reptile's
body, help retain moisture, and aid movement, and it is responsible for body
coloring and patterns.

Vertebrate reptiles
Reptiles exhibit similar
characteristics to other vertebrates such as
Mammals and birds
And some
Amphibians
، They have a spine that includes the
spinal cords that extend along their bodies, and reptiles also contain chains
of bony elements from the tail to the head ,
The function of the internal structure is to protect internal tissues and also helps in body movement.
Reptiles breathe through the lungs
Reptiles have highly developed lungs.
All reptiles rely on their lungs to breathe air, so even species with permeable skin and other adaptations never breathe fully without using their lungs.
Reptiles have four legs
Reptiles usually have four legs,
because they fall from the four-legged breed, in addition to the presence of a
tail in some of them to help them move and catch objects and can help them
climb, In fact, some reptiles, such as crocodiles, have claws on their feet,
and these claws help in movement and hunting.
Classification of mammals
Cold-blooded reptiles
Most vertebrate reptiles are
cold-blooded and do not have the means to regulate their body temperature and
therefore must rely on the external environment,
Reptiles often lie in the sun or hibernate during cold seasons to raise their body temperature, and when the sun is very hot, they remain in shaded areas or inside the water to cool or lower their body temperature.
Reptiles reproduce by eggs
Reptiles often reproduce their eggs,
with the exception of some snakes and lizards that give birth to young.
All
reptiles lay their eggs in the nest ، In
fact, the soil temperature at this time determines whether the young are born
male or female, and are not sexual.
Reproduction is very rare but is known to occur in some species of lizards and snakes.
Reptiles have short digestive tracts
Reptiles have short digestive tracts, but with few exceptions, reptiles are omnivores and, due to their slow metabolism, can tolerate slow digestion and small meals.

Chemical reception in reptiles
Many reptiles have the advantage of
chemoreception
(chemoreception)
، Most
have chemically sensitive organs in the nose or roof of the mouth to identify
prey, and this ability complements or replaces the sense of smell.
