• (A) - (II), (B) - (IV), (C) - (III), (D) - (I)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Connecting the Ostracods directly to "Seed shrimp" and Stomatopods to "Mantis shrimp" are two highly reliable shortcuts for solving carcinology matching questions.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Crustaceans are divided into diverse classes and orders, each with distinct morphological shapes.
Many tiny or specialized crustaceans are given descriptive common names resembling other organisms (like clams, seeds, or praying mantises).

Step 2: Detailed Explanation:
Let us match each common crustacean with its taxonomic group:
Mantis shrimp belong to the order Stomatopoda, characterized by powerful raptorial claws resembling those of a praying mantis.
Therefore, (A) matches with (II).
Clam shrimp are small freshwater crustaceans belonging to the class Branchiopoda (order Spinicaudata or Estheria), encased in a bivalve-like shell resembling a clam.
Therefore, (B) matches with (III).
Seed shrimp belong to the class Ostracoda, which are tiny, bivalved planktonic crustaceans shaped like seeds.
Therefore, (C) matches with (IV).
Opossum shrimp belong to the order Mysida (Mysids), named so because females carry their developing embryos in a pouch (marsupium) under the thorax, like an opossum.
Therefore, (D) matches with (I).
Combining these pairs, we get: (A)-(II), (B)-(III), (C)-(IV), (D)-(I).
This corresponds to Option 3 in the given question paper.

Step 3: Final Answer:
The correct matching sequence is (A) - (II), (B) - (III), (C) - (IV), (D) - (I).
