Introduction

In natureThere is a great variety of animals, which have very different characteristics from each other. One of them is whether or not they have a backbone. In this article, we will talk about the difference between vertebrate and invertebrate animals.

Vertebrate animals

Vertebrate animals are those that have a vertebral column, that is, a bone structure that runs through their body from the head to the tail. These types of animals can be classified into five groups:

• Mammals
• Birds
• reptiles
• Amphibians
• Fish

Vertebrate animals have a great evolutionary advantage, since their spinal column provides protection and support for the body, in addition to being the central axis. nervous system.

Invertebrate animals

On the other hand, invertebrate animals are those that do not have a backbone, so they have other forms of support in the body. There are more than a million species of invertebrate animals, and they can be classified into several groups:

• Insects
• Arachnids
• Molluscs
• Echinoderms
• annelids
• Cnidarians

Invertebrate animals are very varied, and have a great diversity of shapes and sizes. Some of them have very special characteristics, such as the tentacles of octopuses or the pincers of scorpions.

Conclusion

In conclusion, the main difference between vertebrate and invertebrate animals is the presence or absence of a vertebral column. Vertebrate animals have a bony column that provides protection and support for the body and the nervious system, while invertebrate animals have other forms of support in the body. Both types of animals have a great diversity of shapes and sizes, and each has very interesting characteristics.
