No, crayfish are not members of the superfamily called the Deuterostomes. They belong to the superfamilies' Parastacoidea and Astacoidea.
Deuterostome. Anus is formed first.
Sponges are animals of the phylum Porifera
No, a jellyfish is not a deuterostome. Jellyfish belong to the phylum Cnidaria, which is classified as a group of invertebrates called radiate animals. Deuterostomes, on the other hand, include animals such as chordates and echinoderms, characterized by their embryonic development where the anus forms before the mouth. Therefore, jellyfish are part of a different developmental lineage.
No, kitchen sponges nowadays are usually made from cellulose or synthetic plastics. Real marine sponges were used by early Europeans to also clean, but it was stopped due to overfishing that almost brought the sponges to extinction.
No, barrel sponges do not migrate. They are sessile organisms, meaning they are permanently attached to a surface and do not move from one place to another. Barrel sponges rely on water currents to bring them food and oxygen.
no they are neither deuterostome nor prostome because they dont have an alimentary canal. so how can they be any of them? deuterostome are those in which anus forms first then mouth whereas sponges dont have any organ as they are loose aggregate of cells and digestion is intracellular.

Deuterostome. Anus is formed first.
During embryonic development, a deuterostome's first opening is its anus rather than its mouth. Starfish are a type of phylum that is classified as a deuterostome.
Deuterostomes
. A deuterostome with a backbone
deuterostome ^This is actually false porifera are not segmented animals so thay don't form mouth first(Protostones) or butt first (Deuterostomes) so they are under developed being N/a
Chordata is a deuterostome. During development, deuterostomes form the anus first and the mouth second, whereas in protostomes, it is the opposite. Chordates, including humans, exhibit this deuterostome characteristic during embryonic development.
