Chordates are a much larger group, some examples of animals from this phyla are humans, birds, snakes, and fish. In addition, cell development in protostomes is determinate. Cnidarians and ctenophores are in a group called Radiata, and Porifera and Placozoa are in the group known as Parazoa. Moreover, there is a difference between the two in terms of the formation of archenteron, nerve cord, as well as cell development. Hi, I'd like to speak to you. This phylum has five classes and includes animals such as starfish and sea urchins. Chelicerata, and Pancrustacea.

Phylum Porifera are the lowest multicellular animals belonging to thekingdom Animalia. tracheae to breathe, Obelia separate polyps for [23] Opinions differ about whether the Chengjiang fauna fossil Yunnanozoon, from the earlier Cambrian, was a hemichordate or chordate. axis of cleavage plane is oblique, so that blastomeres have a spiral arrangement in which one tier of cells alternates with the next tier of cells. The four features that make a chordate a chordate are a dorsal hollow nerve cord, a notochord, pharyngeal slits, and a post-anal tail. But unlike echinoderms, chordates do not become radially symmetric as adults, and they don't have endoskeletons or water vascular systems. The development is indirect and the cleavage is holoblastic. Animals represent a vast and diverse part of our natural world. The first pair of appendages the chelicerae are used for feeding. These tubular feet are used for breaking, feeding, and movement. Invertebrates do not have a backbone, while vertebrates do have a backbone and make up the largest amount of variation in species. They have the ability to absorb and withhold fluids.
