Fishes have very poor sense organs for

Options

A. Sound perception
B. Vibrations
C. Odours
D. Light perception.

Answer

To solve the question "Fishes have very poor sense organs for," we need to analyze the sensory abilities of fishes in relation to the provided options: sound perception, vibrations, odors, and light perception.

### Step-by-Step Solution:

1. **Understanding Fish Sensory Organs**:
- Fishes have various sensory organs that help them interact with their environment. These include organs for detecting smell, sight, touch, and sound.

2. **Analyzing Each Option**:
- **Sound Perception**: Fishes do not have a specialized organ for hearing like mammals do. While they can detect vibrations in the water, their ability to perceive sound is limited compared to other animals.
- **Vibrations**: Fishes are quite adept at detecting vibrations in the water, which is crucial for their survival. They have specialized organs (like the lateral line system) that help them sense these vibrations effectively.
- **Odors (Smell)**: Many fish, such as sharks, have a highly developed sense of smell. They can detect odors in the water from significant distances, indicating that their olfactory senses are quite good.
- **Light Perception**: Some fish, like dolphins, have good vision and can detect light effectively. Their eyes are adapted to see well in aquatic environments.

3. **Conclusion**:
- After analyzing the options, it becomes clear that fishes have very poor sense organs for **sound perception**. This is the correct answer, as they lack specialized hearing organs and their ability to perceive sound is not as developed as other sensory modalities.

### Final Answer:
Fishes have very poor sense organs for **sound perception**.
