Identify an organism in which brachial respiration takes place

Options

A. Chameleon
B. Peacock
C. Tortoise
D. Shark

Answer

**Step-by-Step Solution:**

1. **Understand Brachial Respiration**: Brachial respiration refers to the process of breathing through gills. This type of respiration is primarily found in aquatic organisms.

2. **Identify Aquatic Organisms**: Since brachial respiration occurs in aquatic organisms, we need to focus on animals that live in water and utilize gills for respiration.

3. **Differentiate Between Aquatic and Terrestrial Organisms**: Terrestrial organisms, such as chameleons and peacocks, use lungs for respiration (pulmonary respiration) and do not perform brachial respiration.

4. **Examine the Options**:
- **Chameleon**: A terrestrial reptile that breathes using lungs.
- **Peacock**: A terrestrial bird that also breathes using lungs.
- **Shark**: An aquatic animal that belongs to the category of cartilaginous fish and breathes using gills.

5. **Select the Correct Organism**: Among the options, the shark is the only organism that performs brachial respiration through its gills.

6. **Conclusion**: Therefore, the organism in which brachial respiration takes place is the shark.
