Animals

Posted about 3 months ago by Ariess233

In the scientific classification of living beings, animals (Animalia) or metazoans (Metazoa) constitute a kingdom that gathers a wide group of organisms that are eukaryotes, heterotrophs, multicellular and tissue (except for porifers). They are characterized by their wide capacity for movement, for having no chloroplast (although there are exceptions, as in the case of Elysia chlorotica) or cell wall, and for their embryonic development; It goes through a blastula phase and determines a fixed body plan (although many species can undergo a subsequent metamorphosis like arthropods). Animals form a natural group closely related to fungi (Fungi kingdom). Animalia is one of the five kingdoms of the Eukaryota domain, and to it belongs the human being.
