Dorsal and ventral fins are continuous with caudal fin in

Options

A. Lung fishes
B. Eel
C. Both A and B
D. Sea Horse

Answer

To solve the question "Dorsal and ventral fins are continuous with caudal fin in," we need to analyze the characteristics of dorsal, ventral, and caudal fins in various fish species. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Fins
- **Dorsal Fin**: This is a single fin located on the back of the fish. It helps in stabilization and maneuvering.
- **Ventral Fin**: Also known as pelvic fins, these are located on the belly of the fish, typically behind the pectoral fins. They assist in balance and steering.
- **Caudal Fin**: This is the tail fin of the fish, which is crucial for propulsion and movement.

### Step 2: Identify the Relationship Between the Fins
- The question specifically asks about the continuity of the dorsal and ventral fins with the caudal fin. In some fish species, these fins are not separate but rather form a continuous structure that merges into the caudal fin.

### Step 3: Examples of Fish with Continuous Fins
- In certain species like **lungfish** and **eels**, the dorsal and ventral fins are indeed continuous with the caudal fin. This means that there is no distinct separation between these fins, allowing for a streamlined body shape.

### Step 4: Conclusion
- Based on the understanding that both lungfish and eels exhibit this characteristic, we can conclude that the correct answer to the question is that dorsal and ventral fins are continuous with the caudal fin in both of these examples.

### Final Answer
The correct answer is **option C**: both lungfish and eels.
