deuterostomes
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.
protostomes
They are protostomes.
Deuterostomes. All chordates such as birds and mammals are deuterosomes.

deuterostomes
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.
no they aren't. T.hey are not protostomes either deuterostomes
embryological development
Yes
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.
jelly fish
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.
