A vertebrate animal has a body with vertebrae
Vertebrate animals are a large group of animals whose
anatomy is provided with a vertebral column, which serves as protection for the
nervous system. The animal is usually provided with bone and / or cartilage
which forms its internal skeleton.
Animals of the animal kingdom that have an internal
skeleton are often easily identifiable. Mammals are all vertebrate animals
because they all have vertebrae, bones, which together form the spine and
skeleton of the animal.
The birds are also vertebrates, but they are simply
covered with feathers and have wings to fly.
Fish also have vertebrae, and will have either bones
or cartilage to form their inner skeleton.
Reptiles and amphibians are also vertebrate animals,
whose snakes are simply not equipped with limbs to move, but have a spine.
Bones in the body of animals have several functions.
Allow parts, such as limbs, to move, but also as protection for more sensitive
organs, such as the ribcage.
The spine is a set of bones in the center of which the
nervous system passes. The other bones that form the skeleton and limbs are
attached to it, usually using cartilage that allows movement between them.

The majority have a skull bone, which protects the
brain from blows, and the attack of predators. The neck is often the place
where the cats will bite their prey, because they break the vertebrae that join
the head to the rest of the body, which kills the animal on the spot.
The vertebrae made it possible for animal species to
evolve thanks to their skeleton which allowed them to move while walking. In
the case of birds, the bones are light enough for them to fly. Bones protect,
and some even have bone plates, like turtles, that are very hard and protect
the animal from predators.
However, the skeleton of a vertebrate animal at its
limits, and it is even fragile in some places like the neck which is often a
weak point. Depending on the type of injury and type of life of an animal, a
fracture of the vertebrae or limb can mean death.
