What characteristics are shared by organisms in each animal phylum?
Organisms are grouped in the phylum by based on the general body plan. In other words, two organisms are in the same phylum if they have similar developmental processes or evolutionary relatedness.
Why are sharks and humans in the same phylum?
Look for the traits of chordates. It is said that both sharks and humans are vertebrates or closely related invertebrates.
What group do Lamprey belong to?
Lampreys are in the same kingdom and phylum as all other fish, they are animals in the phylum Chordata. However, they are in a separate unranked subgroup called the Craniata, which are chordates, but not vertebrates. They are a primitive type of chordate that doesn't have a vertebral column as well as they lack several other vertebrate features.

Yes. Coelenterates are the same as Cnidaria.
