Protostomes & Deuterostomes On the basis of embryonic development, metazoans are divided into Protostomia and Deuterostomia. Protostomes are primitive invertebrates while deuterostomes include echinoderms and chordates. This division helps in understanding relationships of different groups of animals.

Protostomes: Definition and Characteristics The protostomes are a large and diverse group, classified by their shared characteristics. These include having true tissues, being bilaterally symmetric, and developing the mouth before the anus during embryonic development.If it doesn't fit these criteria, it's not a protostome!ome of the most common protostomes are flatworms (such as tapeworms), nematodes (such as heartworms), mollusks (such as snails and slugs), annelids (such as earthworms) and arthropods (spiders, insects, lobsters, ticks, barnacles, and more!).

- C. Pharyngeal pouches. D. Endostyle-elongated groove in the pharynx floor of protochordates that may develop as the thyroid gland in chordates. These four characteristics may be found in some of the ancestors of chordates and are commonly placed in an informal grouping called Protochordates.These serve as living representations of the missing fossils in vertebrate evolution.n contrast to protochordates (hemichordates, urochordates, and cephalochordates), vertebrates are actively-feeding, predatory organisms that move by lateral undulation of an elongate body. Hemichordates and most urochordates are also filter-feeders, moving water through their gill slits, but are sessile as adults.

Echinoderms Echinoderms are also called as Echinodermata and spiny skinned animals. Echinoderms are entirely marine species. They are mostly seen in the inter-tidal zones deep in the ocean and they are also found in the cold and tropical seas. Echinoderms have several unique features that are not found in any other animals.The body wall has a limestone skeletal system called as Stereom. The echinoderms have a special ligament that helps them to stiffen or loosen their body without spending much energy. The males and females echinoderms are separate.ome species of the Echinoderms like starfish are carnivorous, others like sea cucumbers are detritus foragers, and some like basket stars are plankton feeders. Echinoderms have the ability to regenerate their missing organs.

Protozoa Protozoa (meaning first animals) are heterotrophic, single-celled or colonial eukaryotes.lagellates and ciliates use specialized organelles, flagella and cilia, that differ primarily in length and number, to propel the cells through water. Flagella are whiplike structures that usually occur one to a few per cell and have an undulating motion.

- Historically, protozoa were defined as single-celled organisms with animal-like behaviors, such as motility and predation. The group was regarded as the zoological counterpart to the  protophyta , which were considered to be plant-like, as they are capable of photosynthesis.oldfuss erected Protozoa as a class containing what he believed to be the simplest animals. Originally, the group included not only microbes, but also some lower multicellular animals, such as rotifers, corals, sponges, jellyfish, bryozoa and polychaete worms.

Deuterostome The defining characteristic of the deuterostome is the fact that the blastopore (the opening at the bottom of the forming gastrula) becomes the anus, whereas in protostomes the blastopore becomes the mouth.n deuterostomes the mesoderm forms as evaginations of the developed gut that pinch off, forming the coelom. This is called enterocoely. Both the Hemichordata and Chordata have gill slits, and primitive fossil echinoderms also show signs of gill slits.

What are the animal phyla that are protostomes and those that are deuterostomes? The anus is the first hole that forms in the early ball of cells, with the mount forming later, or second, hence second mouth.. The protostomes include all other animal phyla, which means everything which is not a fungus, a plant, or unicellular.So worms, clams, insects, all of these are protostomes (which, by the way, means first mouth).eport Abuse. Protostomia and Deuterostomia are considered super-phyletic taxa, each containing a variety of animal phyla.

Invertebrate vs. Vertebrate In contrast, invertebrates include sponges, coelenterates (Ctenophora or comb jellies; and the Cnidaria or coral animals, true jellies, sea anemones, sea pens, and their allies), echinoderms (starfish, sea urchins, sea cucumbers), worms, mollusks (squid, octopus, snails, bivalves), and arthropods (insects).ifferences in Physical Characteristics. Vertebrates have a skeletal structure with a spinal column or backbone. Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.

- Protostomes like molluscs, annelids, and arthropods develop by spiral cleavage, and their embryonic cells are determinate, the fate of the embryonic cells is fixed very early on in development. The protostome coelom forms from a split within the mesoderm tissue, so they are sometimes refereed to as schizocoels.ivalves form a pair of siphons, sometimes formed by folds of the mantle, which let water in (incurrent siphon) or let water out (excurrent siphon). The flow of water is caused by the beating of the cilia that cover the gills.

Deuterostomes: Definition and Characteristics Deuterostomes include the echinoderms, so things like sea stars, sea urchins, and sand dollars, as well as chordates, which are things like humans, birds, and small marine creatures called lancelets and tunicates.hordates. As mentioned before, because of their similar embryonic development, chordates and echinoderms can be classified together. But unlike echinoderms, chordates do not become radially symmetric as adults, and they don't have endoskeletons or water vascular systems.
