porifera(sponges)

ctenophora(corals)

Answer 2

Explanation:

ctenophora

The phylum derives its name (from the Greek ctene, or “comb,” and phora, or “bearer”) from the series of vertical ciliary combs over the surface of the animal. The body form resembles that of the cnidarian medusa. Various forms of ctenophores are known by other common names—sea walnuts, sea gooseberries, cat's-eyes.

porifera

The approximately 5,000 living sponge species are classified in the phylum Porifera, which is composed of three distinct groups, the Hexactinellida (glass sponges), the Demospongia, and the Calcarea (calcareous sponges). Sponges are characterized by the possession of a feeding system unique among animals.
