Answer 2

Chondrichthyes is a class that contains the cartilaginous fishes: they are jawed vertebrates with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone.

Here JELLY FISH is the answer.

Jellyfish and sea anemones are both part of the phylum Cnidaria. They are multicellular, diploblastic, radial symmetric organisms with nematocysts. Class Scyphozoa consists of cup animals and jellyfish.
