Although most of the animal phyla are included in the deuterostomes and protostomes, cnidaria, porifera, placozoa and ctenophora are not included in the group of animals know as Bilateria (which contains the deuterostomes and protostomes). Cnidarians and ctenophores are in a group called Radiata, and Porifera and Placozoa are in the group known as Parazoa.

Are bivalves protostomes or deuterostomes?
protostomes
Are cnidarians protostomes?
No, cnidarians are not protostomes or deuterostomes. They fall under (the unranked taxonomic level) Radiata, while both superphylum Deuterostomia and Protostomia are under the (unranked taxonomic level) Bilateria. Features of Bilateria include bilateral symmetry (at some point) and three distinctive germ layers, while Radiata only has two.
Are flatworms prokaryote or eukaryote?
They are protostomes.
Are mammalia deuterostomes?
Deuterostomes. All chordates such as birds and mammals are deuterosomes.
Are bivalves protosomes or deuterostomes?
Protostomes .
Does the blastopore becomes the anus of the adult in invertebres sponges protostomes or deuterostomes?
deuterostomes
Are tapeworm pseudocoelomate?
no they aren't. T.hey are not protostomes either deuterostomes
The distinction between protostomes and deuterostomes is based on differences in their?
embryological development
Do protostomes and deuterostomes differ in their manner of cell cleavage during embryonic?
Yes
Are homo sapiens deuterostomes?
Yes, humans (Homo sapiens) are deuterostomes. Deuterostomes are a group of animals in which the blastopore (the opening formed during gastrulation) becomes the anus. This is in contrast to protostomes, where the blastopore becomes the mouth. Humans and other vertebrates belong to the deuterostome group.
Are Chordates and echinoderms are both protostomes?
Neither are protostomes. Chordates, Hemichordates, and Echinoderms are all deuterostomes (in that the blastopore forms the anus first). In protostomes, the blastopore forms the mouth first.
Name at least one phylum example of each protostomes and deuterostomes?
jelly fish
