Endoskeleton is seen in earthworm.

Explanation

### Step-by-Step Text Solution:

1. **Understanding the Question**: The question states that "Endoskeleton is seen in earthworm." We need to determine if this statement is true or false.

2. **Classification of Earthworm**: Earthworms belong to the phylum Annelida. This classification is important as it helps us understand the structural characteristics of earthworms.

3. **Characteristics of Annelids**: Annelids, including earthworms, have a segmented body structure. Each segment is muscular, which is crucial for their movement.

4. **Movement Mechanism**: Earthworms move through the soil using muscular contractions and relaxations. This movement is facilitated by their muscular segments rather than a skeleton.

5. **Skeletal Structures**: In biological terms, an endoskeleton is an internal skeleton, and an exoskeleton is an external skeleton. Earthworms do not possess either of these structures. Instead, they have a hydrostatic skeleton, which relies on fluid pressure within their body segments.

6. **Comparison with Other Organisms**: While insects have exoskeletons made of chitin, earthworms do not have exoskeletons or endoskeletons. This further confirms that the statement in the question is incorrect.

7. **Conclusion**: Based on the characteristics of earthworms and their classification, we conclude that the statement "Endoskeleton is seen in earthworm" is false.

### Final Answer: The statement is false.
