2. **Identifying the Source of Hypnotoxin:**
- It is found in the tentacles of cnidarians, which are organisms that possess specialized cells called nematocysts. These nematocysts contain a fluid that is toxic.

3. **Composition of Hypnotoxin:**
- The fluid within the nematocysts, known as hypnotoxin, is characterized as being proteinaceous in nature. This indicates that it is primarily made up of proteins.

4. **Function of Hypnotoxin:**
- Hypnotoxin serves as a neurotoxin, meaning it affects the nervous system of prey, paralyzing them. This function is crucial for the survival of cnidarians as it aids in capturing prey and serves a defensive purpose.
