Question

Jelly fish belongs to class

• A. hydrozoa
• B. scyphozoa
• C. anthozoa
• D. none of these.

Answer 1

The Correct Option is B

The question asks which class jellyfish belong to, and the options given are hydrozoa, scyphozoa, anthozoa, and none of these. Let's examine each option:

• Hydrozoa: This is a class within the phylum Cnidaria, which includes a variety of species, like hydras and Portuguese man o' war. Although some members of Hydrozoa may look similar to jellyfish, they are not true jellyfish.
• Scyphozoa: This class is known as the "true jellyfish" and most species of jellyfish belong to this class. Scyphozoa is characterized by their large, medusa-dominated life stage, which is the typical form people recognize as jellyfish.
• Anthozoa: This class includes animals like coral and sea anemones, which generally do not have a medusa (jellyfish-like) life stage.
• None of these: This option can be ruled out as we have identified that jellyfish indeed belong to Scyphozoa.

Based on the explanations above, Scyphozoa is the correct class for jellyfish, as they are referred to as the "true jellyfish" within the phylum Cnidaria.

Therefore, the correct answer is: Scyphozoa.
