Which one of the following is a Cladoceran zooplankton
Show Hint
Daphnia and Moina are the two most common cladocerans cultivated in hatcheries as live food for larval fishes.
Updated On: Jul 9, 2026
- Bachionus
- Keratella
- Daphnia
- Fillinia
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Zooplankton in freshwater ecosystems are classified into several taxonomic groups, primarily Rotifers, Cladocerans, and Copepods.
Step 2: Detailed Explanation:
Let us classify the genera provided in the options:
1. Brachionus (spelled as Bachionus) - Rotifera
2. Keratella - Rotifera
3. Filinia (spelled as Fillinia) - Rotifera
4. Daphnia - Cladocera
Cladocerans are small crustaceans commonly known as "water fleas".
They have a distinct bivalve-like carapace covering their body, which is a key structural feature separating them from rotifers and copepods.
Step 3: Final Answer:
The cladoceran zooplankton among the options is Daphnia.
