Options

A. Ichthyophis
B. Cryptobranchus
C. Ambystoma
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Parental Care in Amphibians**: Parental care refers to the behaviors exhibited by some amphibians to protect and nurture their offspring after they are laid. This can include guarding eggs, keeping them moist, and ensuring their safety from predators.

2. **Identifying Amphibians Known for Parental Care**: Among amphibians, some species exhibit more parental care than others. It is essential to identify which amphibian is particularly noted for its parental care.

3. **Focusing on Ichthyophis**: The Ichthyophis, a genus of caecilians, is highlighted as a prime example of parental care in amphibians. The female Ichthyophis lays her eggs near water bodies and is actively involved in caring for them.

4. **Describing the Care Provided by Ichthyophis**: The female Ichthyophis keeps the eggs moist by rotating them and ensuring they are protected from predators. This behavior is crucial for the successful incubation of the eggs.

5. **Hatching and Development**: Once the eggs are ready to hatch, the female Ichthyophis leaves the area, allowing the larvae to hatch and develop their gills. The larvae then move to water bodies to continue their development.

6. **Comparing with Other Amphibians**: Other amphibians, such as Cryptobranchus and Ambystoma, do not exhibit the same level of parental care. They typically abandon their eggs after laying them, which contrasts with the attentive care shown by Ichthyophis.

7. **Conclusion**: Based on the information, the best example of parental care in amphibians is the Ichthyophis, as it demonstrates significant involvement in the nurturing and protection of its offspring.

**Final Answer**: A good example of parental care in amphibians is the Ichthyophis.
