  1. Protostomes vs Deuterostomes

    Deuterostome

    Deuterostomes comprise a superphylum of animals. It is a sister clade of Protostomia, with which it forms the Nephrozoa clade.

    The key difference between protostomes

    Protostome

    Protostomia is a clade of animals. Together with the deuterostomes and xenacoelomorpha, its members make up the Bilateria, mostly comprising animals with bilateral symmetry and three germ layers. The major distinctions between deuterostomes and protostomes are found in em…

    and deuterostomes is the fate of the blastopore

    Blastopore

    A blastopore is an opening into the archenteron during the embryonic stages of an organism. The distinction between protostomes and deuterostomes is based on the direction in which the mouth develops in relation to the blastopore. Protostome derives from the Greek word protostoma meaning "first mouth" whereas Deuterostome's etymology is "second mouth" from the words second and mouth. The major dist…

    during their embryonic development
    . The blastopore in a protostome develops into a mouth, whereas the blastopore in deuterostomes develops into an anal opening.

    What are protostomes and deuterostomes in invertebrates?
    The majority of coelomate invertebrates develop as protostomes ("first mouth") in which the oral end of the animal develops from the first developmental opening, the blastopore. In the deuterostomes ("second mouth": cf.

    Why archenteron forms in deuterostomes but not in protostomes?
    Archenteron forms in deuterostomes, but not in protostomes. In addition, cell development in protostomes is determinate. Protostomes and Deuterostomes are two groups of coelomates. The difference between protostomes and deuterostomes is mainly based on the fate of blastopore and cleavage during embryonic development.

    What is an example of a deuterostomy?
    Some examples of deuterostomes include vertebrates, sea stars, and crinoids. In deuterostomy, the developing embryo's first opening (the blastopore) becomes the anus, while the mouth is formed at a different site later on.

    What is the difference between blastula and deuterostome?
    Blastula undergoes gastrulation after formation. During the gastrulation, blastopore becomes anus in deuterostomes. After the formation of the anus, another cavity called archenteron runs through the gut, leading to the formation of the mouth in deuterostomes. The archenteron has longitudinal cavities and those become the coelom in deuterostomes.
