1. **Understanding Sponges**: Sponges belong to the phylum Porifera. They are multicellular organisms characterized by their porous bodies, which allow water to circulate through them.

2. **Body Structure**: Sponges have an asymmetrical body plan, meaning that if you were to cut them in half, the two halves would not be identical. They possess the simplest body structure among animals.

3. **Habitat**: Sponges are primarily found in marine environments, but they can also inhabit brackish water. They thrive in warm waters and require specific temperature conditions for survival.

4. **Cold Water**: The question asks where sponges are not found. Based on their habitat preferences, sponges do not thrive in cold water. They need warmer temperatures to survive and function properly.

5. **Conclusion**: Therefore, the answer to the question "Sponges are not found in" is cold water.
