Which structures of earthworm are analogous to kidneys of the vertebrates?

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the structures in earthworms that are analogous to the kidneys found in vertebrates. The term "analogous" means that while the structures may be different in form and complexity, they perform similar functions.

2. **Identifying the Structure in Earthworms**: In earthworms, the structures that perform a function similar to that of kidneys in vertebrates are called **nephridia**.

3. **Function of Nephridia**: Nephridia are responsible for the excretion of waste materials from the body of the earthworm. They help in the removal of nitrogenous waste and other metabolic by-products.
