An invertebrate is an animal without a backbone. Invertebrate animals include fruit flies and sea sponges. Your backbone allows you to stand up straight, and it also allows you to be grouped with the other vertebrates: animals with backbones. Invertebrates are the opposite: they have no backbone.
What is the main difference between invertebrates and vertebrates?
The major difference between Vertebrates and Invertebrates is that Vertebrates(e.g human beings) have a backbone or spinal cord whereas invertebrates lack backbone.Vertebrates are always bilaterally symmetrical, while invertebrates could show either bilateral or radial symmetry.
What is meant by vertebrates and invertebrates?
A vertebrate is an animal that has a backbone and a skeleton. Vertebrate animals include humans. When you think about vertebrates, think about bones: this word has to do with animals that have a lot of bones, in the form of a skeleton. Animals without a backbone are called invertebrates.
