Question
Hydras are members of which class of Cnidaria?
Group of answer choices:
- Class Scyphozoa
- Class Anthozoa
- Class Polyplacaphora
- Class Hydrozoa
Solution
Step 1: Break Down the Problem
To determine which class of Cnidaria hydras belong to, we need to analyze the available options and identify the correct classification.
Step 2: Relevant Concepts
- Cnidaria: A phylum that includes organisms like jellyfish, corals, and hydras, characterized by the presence of cnidocytes (stinging cells).
- Classes of Cnidaria:
- Class Scyphozoa: Includes jellyfish.
- Class Anthozoa: Includes corals and sea anemones.
- Class Polyplacophora: This is not a class of Cnidaria; it refers to a class of mollusks.
- Class Hydrozoa: This class includes hydras and is characterized by both polyp and medusa stages.
Step 3: Analysis and Detail
- The correct classification of hydras is explicitly part of the Class Hydrozoa within the phylum Cnidaria.
- The options presented include three relevant classes of Cnidaria and one unrelated class (Polyplacophora).
Step 4: Verify and Summarize
Upon reviewing the options and confirming that hydras are classified under Hydrozoa, we find that the other classes do not include hydras.
Final Answer
Class Hydrozoa
