Vertebrate and Invertebrate Animal Groupings. Vertebrates and invertebrates are two groups of animals with different structures in their bodies. There are so many animals that exist on this earth.
One of the ways to distinguish them is by looking at the structure of their bodies. Then what are invertebrates and vertebrates?
Vertebrates and Invertebrates
Vertebrate and Invertebrate Animal Groupings. There are many types of animals that exist on earth. Meanwhile, there are groups of animals that are divided into two based on the structure of their bodies.
These animals are a group of vertebrates and a group of invertebrates. The following is an explanation of the two groups of animals.
Vertebrate Animal Group
Vertebrate animals are a type of animal group that has a backbone. With this understanding, animals belonging to the vertebrate group are animals that have a backbone.

Besides that, there is a brain that is also able to work perfectly. Also, this group of animals has a complete digestive apparatus.
The difference between vertebrates and invertebrates is that their bodies can move actively and almost all of these animals have separate heads and bodies.
Examples of animals with backbones are divided into several types, namely:
This type of animal can live in water as well as on land. The respiratory system is the lungs and skin. Examples of amphibians such as newts, frogs, and salamanders.
This animal is an animal that can only live in water. It moves through fins and breathes with gills. The reproduction of these animals is by laying eggs.
The respiratory system of this animal is the lungs. Reproduction by laying eggs. Examples of animals such as crocodiles, lizards, snakes, and lizards.
This type of animal can fly and has hair all over its body. There are also flightless birds, namely chickens, ducks, and penguins.
This grouping of vertebrates and invertebrates are animals that breastfeed their children. The way they reproduce is by giving birth. Examples of these animals are cows, dogs, cats, goats, whales, and dolphins
Invertebrate Animal Group
Quoted from Wikipedia, this group of animals is an animal that has no backbone or is also known as invertebrates. Invertebrate animals are also divided into several types of animals, including:
This type of animal is living in the sea with a tube-like body. It eats from small marine animals or bacteria in the sea.
The body size of this animal is very small. They like to eat plants and animals too. Their bodies can only be seen through a microscope. These animals can live anywhere, even in the human body.
Examples of this type of animal are such as insects, centipedes, spiders, fleas, scorpions, and shrimp.
This type of animal has many examples of about 10 thousand types that belong to it. Suppose worms and leeches. This grouping of vertebrates and invertebrates has habitats on land and also in water.
This type of animal is an animal with a cavity in its body. Such as corals, sea anemones, and jellyfish.
Examples of this type of animal are snails, clams, squids, and oysters.
This animal is included in the animal whose body is flat. Suppose that the tapeworm and also the shaking hairworm.
Examples of this type of animal are hookworms and filarial worms. The shape of the body at both ends is tapered with a rounded center.
This grouping of vertebrates and invertebrates has the characteristic of being animals whose habitat is in the sea. Suppose the star snake, sea urchin, and also sea cucumber.
The majority of animal species are invertebrates. There is even an idea that this group of animals achieved 97 percent dominance.
The diversity possessed by invertebrates is much greater when compared to vertebrates. The size of the invertebrates is very variable. Ranging from 0.002 inches to 9-10 meters.
In fact, some invertebrates are more closely related to vertebrates than are other invertebrates. They are tunicates as well as cephalochordates.
Thus, making invertebrates is paraphyletic and is called taxonomy. The difference between vertebrates and invertebrates can be a source of knowledge about animal grouping.
