Question:

The umbrella shaped and free-swimming form of Cnidarians is not present in

Options:

1. Aurelia
2. Jellyfish
3. Adamsia
4. Both 1 and 2

Solution:

Adamsia has polyp form. The umbrella-shaped and free-swimming form, known as a medusa, is a characteristic feature of jellyfish, which belong to the class Scyphozoa within the phylum Cnidaria. Aurelia, commonly known as moon jellyfish, is a type of jellyfish that exhibits the medusa form. Adamsia, on the other hand, is a species of sea anemone, which is a member of the class Anthozoa within the phylum Cnidaria. Unlike jellyfish, sea anemones do not have a medusa form, and they typically do not exhibit free-swimming behavior.
