Hypnotoxin is produced by

Options

A. Sponges
B. Bath sponge
C. Nematocysts
D. Leucosolenia

Answer

To answer the question "Hypnotoxin is produced by," we can follow these steps:

### Step 1: Understand the term "Hypnotoxin"
Hypnotoxin is a type of neurotoxin that can induce a state of unconsciousness in prey. It is associated with certain organisms that have specialized cells for capturing prey.

**Hint:** Research what hypnotoxin does and its biological significance.

### Step 2: Identify the organisms mentioned in the options
The options provided are:
- Sponges
- Bath sponge
- Nematocyst
- Leucoselania

**Hint:** Familiarize yourself with the characteristics of each of these organisms.

### Step 3: Analyze the role of Nematocysts
Nematocysts are specialized cells found in cnidarians (like jellyfish, corals, and sea anemones) that contain stinging capsules. These capsules can inject toxins into prey, which can include neurotoxins like hypnotoxin.

**Hint:** Look into the structure and function of nematocysts and their role in cnidarians.

### Step 4: Evaluate the options
- **Sponges** and **bath sponge**: These organisms do not produce hypnotoxin. They lack the specialized cells (nematocysts) that are characteristic of cnidarians.
- **Nematocyst**: This is the correct answer since they are the stinging cells that produce hypnotoxin.
- **Leucoselania**: This is also incorrect as it does not produce hypnotoxin.

**Hint:** Compare the characteristics of the organisms to determine which one is associated with the production of hypnotoxin.

### Step 5: Conclusion
Based on the analysis, the correct answer is that hypnotoxin is produced by **nematocysts**.

**Final Answer:** Hypnotoxin is produced by nematocysts.
