Ashley is taking a test. She has to write why comb jellies and jellyfish belong to two different phyla. What should Ashley write?

A that jellyfish are vertebrates, while comb jellies are not

B. that jellyfish are mobile, while comb jellies are not

C. that jellyfish have stinging cells, while comb jellies do not

D.

that jellyfish have an exoskeleton, while comb jellies do not

Answer: C. That jellyfish have stinging cells, while comb jellies do not

Explanation:

Comb Jellies to the untrained eye are the same as Jellyfish but as the question says, they are different in that they belong to different phyla.

The Comb Kelly belongs to the Ctenophora Phylum while the Jellyfish belongs to the Coelenterate phylum.

Perhaps the largest difference between them is that Ctenophora do not have stinging cells as opposed to members of the Coelenterate Phylum that do.
