The correct Answer is:
To solve the matching question regarding the structures and examples of fishes, we will analyze each structure and its corresponding example step by step. ### Step-by-Step Solution: 1. **Identify Structure A: Hypotrematic** - Hypotrematic refers to a condition where the gill slits are located on the ventral (underside) side of the head. This is characteristic of certain species of skates. - **Match:** A) Hypotrematic → 3) Skate 2. **Identify Structure B: Heteroceral caudal fin** - The heteroceral caudal fin is a type of tail fin that is asymmetrical, commonly found in sharks. It helps in propulsion and maneuverability. - **Match:** B) Heteroceral caudal fin → 1) Shark 3. **Identify Structure C: Operculum** - The operculum is a bony flap that covers the gills in bony fishes (Osteichthyes). It is not present in cartilaginous fishes (Chondrichthyes). - **Match:** C) Operculum → 4) Osteichthyes 4. **Identify Structure D: Spiral valve** - The spiral valve is a corkscrew-shaped structure found in the intestines of some fishes, particularly in cartilaginous fishes (Chondrichthyes) like sharks and rays. - **Match:** D) Spiral valve → 2) Chondrichthyes ### Final Matches: - A) Hypotrematic → 3) Skate - B) Heteroceral caudal fin → 1) Shark - C) Operculum → 4) Osteichthyes - D) Spiral valve → 2) Chondrichthyes ### Correct Answer: The correct matches are: - A - 3 - B - 1 - C - 4 - D - 2
