Description

good day   welcome.
characteristics
Snails are a group of animals that are eukaryotic organisms as members of the animal kingdom. This implies that the genetic material (DNA) in their cells makes up chromosomes. These are separated in a structure called the cell nucleus.
Similarly, gastropods (a group to which snails belong), present three germ layers during embryonic development. In addition, it has an internal cavity called coelom, hence they are also considered as coelom.
Snails have bilateral symmetry, which means that drawing an imaginary line along the animal's longitudinal axis results in two exactly equal halves.
Snails undergo a stress process at a certain point in their embryonic development that is unique to this group of animals. During this process, the visible mass of the animal undergoes a turn of the foot and head.
classification
The taxonomic classification of snails is as follows:
-Domain: Yukarya
-Animal Kingdom
-Philo: Mollusca
-Genus: Gastropoda
-Sublas: Orthopedic grip
-Superden: Heterobranchia
Order: Pulmonata.
Morphology
When it comes to the morphology of snails, what stands out is the presence of a shell. Its texture is quite hard, strong and resistant. Similarly, your body is made up of three regions or regions: the head, the base, and the visible mass.
Shell
It is generally made up of three layers:
- Nacre: It is the innermost layer and is attached to the body of the animal.
- Mesostraco: Intermediate layer made of calcium carbonate.
- Periostracus: It is the outer layer and is made of scleroprotein called conchiolin.
Similarly, the shells of gastropods are characterized by the fact that they experience certain stresses during their development.
