5 Classification of Animals with backbones, these are the characteristics and examples

  • Share

Animals with backbones are also called vertebrates. The main feature is that these animals have a backbone in their body. Then, what are examples of vertebrate animals that children should know? Check it out in this article!

The spine is a column of bone that supports the body and protects the spinal cord. The backs of these animals are composed of many separate bones called vertebrae.

Well, it is this backbone that plays an important role in supporting most of the inner skeleton. All vertebrate animals have these characteristics with additional features and shapes that vary according to their class. For example, in mammals the legs can be in the form of hands and feet while in fish they are fins.

Classification of vertebrates

Classification of vertebrate animals is further divided into smaller classes. There are 5 classes in the vertebrate subphylum, namely mammals (mammals), birds, reptiles, amphibians, and fish. See also examples of vertebrate animals from each class.

1. Mammals, Lactating Vertebrates

Mammals or also called mammals are a class in vertebrate animals with the characteristics that match the name, namely being able to breastfeed. Classes of mammals, especially in females, are characterized by the presence of mammary glands on their bodies which function to provide food for their young.

Most mammals also have a larger brain size than animals from other classes, and most of their bodies are covered with hair or fur. Mammals have warm blood (homoiterm), which is a group of animals that have heat receptors in their bodies so they can produce their own heat.

Mammals are further classified into smaller orders. For example, the orders of rodents such as mice, squirrels and rabbits; primate animal orders such as monkeys, gorillas, and chimpanzees; the order of ungulates (ungulata), such as horses, giraffes, zebras; order of carnivores, such as cats and dogs.

Animals in the Aves class are characterized by the presence of fur (in contrast to hair in mammals), having a beak and no teeth, breeding by laying eggs, and being warm-blooded.

Leg features in birds in the form of a pair of legs and a pair of wings. Birds also have strong but light bones, making it easier for them to fly. However, not all birds can fly.

Examples of bird vertebrate animals that can fly are eagles, crows, sparrows. While birds that can not fly such as penguins, ostrich, and kiwi.

3. Reptiles include animals with backbones

Reptiles are also known as reptiles. Some of the characteristics of reptiles are having dry skin, and covered by scales or horn plates (a hard substance that covers the skin).

Most reptiles have two pairs of legs as a means of locomotion, which can be legs like in lizards or flippers like in turtles.

Unlike birds and mammals, reptiles have cold blood (poikilotherm), which is a group of animals that do not have heat receptors in their bodies so that their body temperature adjusts to the ambient temperature. Examples of reptiles are lizards, crocodiles, turtles and snakes.

Amphibians are better known as animals that can live in two realms, land and water. Amphibians have the characteristics of being cold-blooded animals; have thin, smooth and porous skin that is usually slimy, even some species have poisonous skin, such as the type of dart frog in the Amazon forest.

Compared to other vertebrate animals, amphibians are the only ones that undergo metamorphosis, i.e. have a life cycle that starts from a larva that breathes with gills until it becomes an adult and breathes with lungs. Examples of amphibians are frogs and salamanders.

5. Fish (Pisces), Including Types of Animals with backbones or Vertebrates

Fish are vertebrates that live entirely in water and breathe through gills. In contrast to other classes of vertebrates, which mostly have legs in the form of a pair of legs and arms, fish have limbs in the form of fins, which function like oars on a boat, which makes it easier for them to swim and move in the water.

Most fish have a hard skeleton as in other vertebrates, but some species, such as sharks and rays, have a soft skeleton called cartilage or cartilage. Fish also have scales that cover their skin. Most fish have cold blood.

There are more than 34,000 types of fish that live in both fresh and salt water. Examples of animals from the fish class are catfish, stingrays, and sharks.


Well, that was the types of vertebrate animals and examples of vertebrate animals from each class. Hopefully this information is useful, yes.
