They live in a way that they breathe, go through respiration, reproduce their off springs, also consume food and grow.

The majestic kingdom, which is none other than the Kingdom Animalia, is divided into seven major and most common types which are these:

The most easily understood and commonly found out of the whole animalia kingdom is this type which is called Mammals. Also, it is known as ‘mammalia’ as the scientific name for Mammals. The animals are from the mammalia class out of animal kingdom and this class was discovered and explored by the famous name from the historians and animalists category, Carolus Linneaus. The discovery and research is known to be done and made public back in the year 1758.

The most famous characteristic of this type is that the female mammals lay eggs and most of them feed their off springs from their own milk.


Birds are another category from the kingdom animalia is the birds or you can also call this category by its scientific name which is ‘Aves’. Birds or Aves are from the class ‘Aves’ and the phylum for birds in the hierarchy is named as ‘Chordata’. One of the most beautiful creatures of the world is birds which have the most natural habitat. They fly and their habitat is sky which is beautiful in its own kind. Also, another major fact for this class of animalia kingdom is that they were also studied by Carolus Linneaus back from the days in 1758.

The class amphibian is named as ‘Amphibia’ scientifically and the phylum from the kingdom animalia is chordata. Amphibians are often taken as tetrapod vertebrates from the class amphibia.

The habitat of this class out of the animals is arboreal and freshwater spaces and the most common species is frog, caecilian, labyrinth and many more.


With a phylum of chordate along with the sub phylum named as vertebrata, vertebrates are another kind of species from the kingdom animalia. The kind was discovered and studied widely by the known J. B. Lamerick back in the early years of 19th century which is 1801.

This is the phylum of the animal kingdom which has the most large number of species found till the date which is almost over 69000 species.


Insects are another class from the animal kingdom and it has the scientific name called as ‘Insecta’. They are also known as the hexapod invertebrate which means that this specie does not have the animals with the back bone. Instead, they are found in a very small size. Major examples are ants, mosquito and even butterflies.


With a common and average life span of 20 years, the aquatic species are mostly considered under the major head of fish. The fish comes under the phylum of Chordata. The animals coming under this head are gill bearing creature who breathe through it. The different species out of this class are known for their speed of traveling through the distance within the sea and ocean waters.
