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 ...

Which of the following organisms are deuterostomes *?
Arthropoda, Mollusca, Echinodermata.
Are deuterostomes divided into two groups?
The deuterostomes, whose name translates as “second mouth,” consist of two phyla: Chordata and Echinodermata. ... The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates. Figure 1.
Which phylum do not belongs to deuterostome?
Earthworm is not a deuterostome. Deuterostomes are distinguished by their embryonic development.
What are the 3 major groups under Protostome?
Protostomes are divided into the Ecdysozoa (e.g. arthropods, nematodes) and the Spiralia (e.g. molluscs, annelids, platyhelminths, and rotifers).
Are arthropods deuterostomes?
Protostomes and Deuterostomes
Mollusks, annelids, and arthropods are protostomes. Echinoderms and chordates are deuterostomes. This distinction is important.
Are sea cucumbers deuterostomes?
Echinodermata – Sea Cucumbers, Sea Stars, Sea Urchins, Sea Lilies, Brittle Stars. These basal deuterostomes have an open circulatory system (as most invertebrates), and the blood cells of their coelomic fluid, referred to as coelomocytes, include both phagocytes and cytotoxic cells (Chia and Xing, 1996).
Are birds deuterostomes?
All chordates (which includes all vertebrates), such as birds and mammals, are deuterostomes. ... The deuterostome mouth develops at the opposite end of the embryo from the blastopore and a digestive tract develops in the middle, connecting the two.
Are snakes deuterostome?
Reptilia—Turtles, snakes, crocodiles, lizards. These are ectothermic animals with scales and lungs. Aves—Birds. These are endothermic animals with feathers and beaks.
Are Cnidaria deuterostomes?
Cnidaria are neither protostomes or deuterostome, as both of these superphylum belong to the Bilateria clade of animals, animals that exhibit...
Is a frog a deuterostome?
Chapter 27Deuterostomes. ... This chapter discusses some general features of glycosylation and glycan-binding interactions in a few species that belong to the deuterostome lineage, with particular emphasis on sea urchins, frogs, zebrafish, and mice.
Are mollusks deuterostomes?
Molluscans are protostomes.
Their mouth arise from the embryonic blastopore. ... The blastopore becomes mouth in protostomes (i.e. mouth appeared first) while in deuterostomes it forms anus (i.e. mouth appears later).
What are the two main groups of protostomes?
The protostomes can be divided into two major clades—the lophotrochozoans (including bryozoans, annelids, and mollusks) and the ecdysozoans (including nematodes and arthropods)—largely on the basis of DNA sequence analysis.
What is Deuterostome in biology?
Definition of deuterostome
: any of a major division (Deuterostomia) of the animal kingdom that includes the bilaterally symmetrical animals (such as the chordates) with indeterminate cleavage and a mouth that does not arise from the blastopore.
What is a Protostome and Deuterostome?
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.
