Vertebrates

Vertebrata (sometimes named Craniata) are a subtype of chordates (the most complexly constructed animal organisms). Unlike other chordates, vertebrates actively provide food. This active diet is enabled primarily by the developed skeleton, complex sensory organs, and differentiated cranial brain.

Vertebrates have developed sensory organs for hearing, smell, and sight, as well as brain development that regulates all of the body’s activity. They have a closed circulatory system supplied with a contractile organ – the heart. Intense gas circulation is ensured by well-developed respiratory organs – gills or lungs. All of these, as well as some other opportunities that vertebrates have acquired in their evolutionary development, have given them the opportunity to reach the highest level of development as animals.

At National park Pelister are present different verterbrate species, such as: Fish (Piscium) – 2 species, Amphibians (Amphibia) – 12 taxa, Reptiles (Reptilia) – 16 taxa, Birds (Аvium) – 116 taxaand Mammals (Mammalia) 47 taxa.
