Question

Match List I with List II
List I (Parental Care): A. Nest builder, B. Mouth brooder, C. Pouch brooder, D. Live bearers
List II (Fish Species): I. Hippocampus kelloggi, II. Poecilia reticulata, III. Oreochromis mossambicus, IV. Betta splendens
Choose the correct answer from the options given below:

• A. A - II, B - III, C - IV, D - I
• B. A - III, B - II, C - IV, D - I
• C. A - IV, B - III, C - II, D - I
• D. A - IV, B - III, C - I, D - II

Hint:

Tilapia reproduction:
- Oreochromis = Maternal mouth brooder.
- Sarotherodon = Biparental or Paternal mouth brooder.
- Tilapia = Substrate spawner (nest builder).
Knowing the genus helps distinguish the breeding habit!

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks to match different types of parental care or reproductive strategies with representative fish species.
Detailed Explanation:

• Nest Builder (A): Betta splendens (Siamese fighting fish) is a well-known bubble-nest builder. The male creates a nest of bubbles at the water surface and guards the eggs until they hatch. (A matches IV).

• Mouth Brooder (B): Oreochromis mossambicus (Mozambique tilapia) is a maternal mouth brooder. The female carries the fertilized eggs and later the fry in her buccal cavity (mouth) for protection. (B matches III).

• Pouch Brooder (C): Hippocampus kelloggi (Seahorse) exhibits extreme paternal care. The female deposits eggs into a brood pouch on the male's abdomen, where they are fertilized and incubated. (C matches I).

• Live Bearers (D): Poecilia reticulata (Guppy) is an ovoviviparous fish. Fertilization is internal, and the female gives birth to free-swimming young ones rather than laying eggs. (D matches II).

Step 2: Final Answer:
The correct matching is A-IV, B-III, C-I, D-II. This corresponds to Option (D).
