Vertebrate Characteristics

Vertebrates are a series of animals that have a central bone system, which has a spinal cord that carries all the neuronal information of each animal.

There are different types of vertebrate animals or their classifications, in which we can differentiate the following:

1. Mammals
2. Birds
3. Fishes
4. Reptiles
5. Amphibians

And from here we can make a new division:

1. Herbivores and
2. Carnivores

And we make one more division between:

1. Viviparous and
2. Oviparous

Vertebrates have different physical formations and different capacities but are distinguished by having its vertebral column which in some animals extends as the tail or in the marine ones as the final fin.

Aspects and characteristics of vertebrates:

Vertebrates are animals that have the only common point of having the spine and every vertebrate has a leisure system. There are five divisions of vertebrates and we have already issued it above.

1. Fishes.- Fish can be considered as the most primitive vertebrates, by deduction than from the evolution has been carried out, notably by Charles Darwin and other scholars of the evolution of species. In the marine world there are oviparous vertebrates and viviparous vertebrates, as well as marine mammals and animals that breathe through gills.

2. Birds.- Birds form one of the most abundant ranges of vertebrates, as there are an immense number of birds and many varieties or subspecies. Among the birds are inexpensive
3. Mammals.- Mammals in their entirety are vertebrates, these range from marine whales and some dolphins, to humans, monkeys, equines, pachyderms, etc.
4. Reptiles.- Reptiles also form a broad segment of vertebrates, since crocodiles, lizards, snakes, etc. can be included here, and finally we have:
5. Amphibians.- Amphibians are oviparous vertebrate animals, they feed on insects and small fish and algae their Initial respiration is through gills and later passes to pulmonary respiration or respiration through the skin.
