In which phylum the mantle cavity is found?

Answer

To answer the question "In which phylum is the mantle cavity found?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Phylum**: The mantle cavity is specifically found in the phylum **Mollusca**. This phylum includes a diverse group of animals such as snails, clams, squids, and octopuses.

2. **Understanding the Structure**: In Mollusca, the body is organized into three main parts: the **head**, the **muscular foot**, and the **visceral hump**.

3. **Locate the Mantle**: The **mantle** is a significant structure in mollusks. It is a soft, spongy layer of tissue that covers the visceral hump.

4. **Define the Mantle Cavity**: The **mantle cavity** is the space between the mantle and the visceral hump. This cavity serves important functions, including housing the gills (or lungs in some species) and facilitating respiration.

5. **Conclusion**: Therefore, the mantle cavity is a characteristic feature of the phylum **Mollusca**.

### Final Answer:
The mantle cavity is found in the phylum **Mollusca**.
