Animal with pseudocoelom is

Options

A. Amia//Leech
B. Lepisma//Liver Fluke
C. Dragon Fly // Jelly Fish
D. Wuchereria//Hookworm

Answer

To determine which animal has a pseudocoelom, we need to follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Coelom**:
- Coelom refers to a fluid-filled cavity that is found between the digestive tract and the body wall. It can be classified into three types: acoelomate (no coelom), pseudocoelomate (false coelom), and coelomate (true coelom).

2. **Identify the Types of Animals Based on Coelom**:
- Acoelomate: Animals that lack a coelom (e.g., flatworms).
- Pseudocoelomate: Animals that have a pseudocoelom, which is a body cavity that is not completely lined by mesoderm (e.g., roundworms).
- Coelomate: Animals that have a true coelom, which is completely lined by mesoderm (e.g., annelids, mollusks).

3. **Focus on Pseudocoelomate Animals**:
- We need to find examples of pseudocoelomate animals. The most common example is the phylum Nematoda, which includes roundworms.

4. **Evaluate the Given Options**:
- If the question provides options, we need to analyze each option to determine which one represents a pseudocoelomate animal.
- For instance, if the options include animals like roundworms (Nematoda), then that would be the correct answer.

5. **Conclude the Correct Answer**:
- Based on the analysis, if roundworms are listed as an option, we can conclude that they are the animals with a pseudocoelom.

### Final Answer:
The animal with a pseudocoelom is the **roundworm** (Nematoda).
