In this world there are varieties of species of different kinds of creatures. Inorder to study these variety of creatures the animal kingdom are divided according to their backbone. The two kinds of animals are vertebrates and invertebrates.
Vertebrates are a group of animals that include fish, amphibians, reptiles, birds, and mammals. The study of vertebrates is important in understanding their biology. Biology is the subject to learn about the animals and other creatures around us. For this the simple and the most important is vertebrates and invertebrates. As the information shows, vertebrates are the creatures who have backbone and invertebrates are the group with no back bones. Vertebrates are very developed compared to invertebrates.
Has been known that invertebrates are divided into 9 groups known as phylum similarly vertebrates also divided into 5 different groups known as classes. It can be complex but let’s simplify on some characteristics of Vertebrates.
Pieces: Animals like fish who live in the water with scales in their body are known as Pieces. Animals like jellyfish, Goldfish, and sharks are some examples of it. They are easily symbolized as fish. They are the most undeveloped class in all the groups of vertebrates. Some of the characteristics they have are below
० They have gills to breathe
० They have won chambered heart
० Their backbone is not that strong as other
० They can only live in water
० Scales help fish to swim.
० They are cold blooded animal
Amphibians
The animals which can live both on land and water but need water to reproduce are called amphibian animals. Amphibians can be similar to reptiles. There fourth most developed classes of vertebrates. Some of the characteristics of amphibians are listed below
० They can live both in land and water
० They live in a warm environment
० Your body is divided into head and trunk
० They are cold blooded animal
० They have three chambered heart
० They have smooth and rough skin but their gland are moist
Reptile
The animals who live eggs and are similar to amphibians but not amphibians are called reptiles. We can find them in cold places. Some examples of reptile art are snakes ,lizards, turtles and alligators. Characteristics of reptiles are:
० They are cold blooded animals
० All the species of reptile have at least one lung
० All the reptiles fertilize egg internally
० Dead body is completely covered with scales
० They have three chambered heart
Aves
Aves are creatures who are covered in feathers and many of them can fly as well. In simple terms they are birds. Some of the examples of aves are Sparrow, pigeon, peacock. Their characteristics are like this
० They are warm blooded animals
० Their body is covered from feathers
० They have four chambered heart
० Many of them can fly
० They lay egg and reproduce
० Their mouth are converted into beck
Mammal
Mammals are the most developed class in vertebrates. The animals who have to cover their body are known as mammals. They are also known as the most smart class. For example elephants, giraffes, human beings, dogs, whales and dolphins. Some of the characteristics are given below:
० Their body is covered from hairs
० They have four chambered heart
० They are warm blooded animal
० They give birth to young ones
० They can be in land and also in water
० The breath through lungs
In conclusion all the creatures are unique and they possess an extraordinary quality. Hence we need to live together without disturbing each other's habitat.
