Question

Detail answer about invertebrates

Answer 1

Answer:

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. These are the two major groups of animals. Also, this word is used for people who are spineless in the sense of having no courage. You could say a coward acts in an invertebrate way. Whether it's a backbone-free animal or a courage-free person, all invertebrates lack spines.

Answer 2

There are over 30 phyla dedicated to invertebrates. Major invertebrate phyla that you should know include porifera, cnidaria, platyhelminthes, nematoda, mollusca, annelida, arthropoda, and echinodermata
