What are the two phyla of deuterostomes?
Deuterostomia, (Greek: “second mouth”), group of animals—including those of the phyla Echinodermata (e.g., starfish, sea urchins), Chordata (e.g., sea squirts, lancelets, and vertebrates), Chaetognatha (e.g., arrowworms), and Brachiopoda (e.g., lamp shells)—classified together on the basis of embryological development …
What animal phyla are included in Protostomia and Deuterostomia?
Some examples of protostomes are nematodes, arthropods, flatworms, annelids and molluscs. Together with the Deuterostomia and Xenacoelomorpha, these form the clade Bilateria, animals with bilateral symmetry and three germ layers….Protostomia.

What are the 4 existing phylum of Deuterostome?
The four major clades of deuterostomes are Chordata (e.g. vertebrates), Echinodermata (e.g. starfish), and Hemichordata (e.g. acorn worms). Together with Protostomia and their out-group Xenacoelomorpha, these compose the Bilateria, animals with bilateral symmetry and three germ layers.

How do you differentiate Protostomia and Deuterostomia?
Protostomes are primitive invertebrates while deuterostomes include chordates and echinoderms. The main difference between protostomes and deuterostomes is that the blastopore in protostomes are developed into a mouth while the blastopore in deuterostomes is developed into an anal opening.
What are the animal phyla that are protostomes?
Protostomia and Deuterostomia are considered super-phyletic taxa, each containing a variety of animal phyla. Traditionally, the protostomes include the Annelida, Arthropoda, and Mollusca, and the deuterostomes comprise the Echinodermata and Chordata.
Which is a protostome and what is a Deuterostomia?
Protostomia and Deuterostomia are considered super-phyletic taxa, each containing a variety of animal phyla. Traditionally, the protostomes include the Annelida, Arthropoda, and Mollusca, and the deuterostomes comprise the Echino-dermata and Chordata.
What are the members of the Protostomia group?
See Article History. Protostomia, group of animals—including the arthropods (e.g., insects, crabs), mollusks (clams, snails), annelid worms, and some other groups—classified together largely on the basis of embryological development.
What kind of animal has a Protostomia mouth?
Protostomia, group of animals—including the arthropods (e.g., insects, crabs), mollusks (clams, snails), annelid worms, and some other groups—classified together largely on the basis of embryological development. The mouth of the Protostomia (proto, “first”; stoma, “mouth”) develops from the first
