The regenerated tail of Wall Lizard is

Options

A. Without vertebrae
B. Similar to normal tail
C. Stumpy
D. Very long

Answer

**Step-by-Step Solution:**

1. **Understanding Tail Autotomy**: The Wall Lizard has the ability to detach its tail when threatened by predators. This process is known as autotomy and serves as a defense mechanism, allowing the lizard to escape while the predator is distracted by the tail.

2. **Regeneration Process**: After the tail is lost, the Wall Lizard can regenerate a new tail. This regeneration process is a remarkable biological phenomenon that allows the lizard to recover from injury.

3. **Characteristics of the Regenerated Tail**: The regenerated tail is not identical to the original tail. One of the key differences is that the new tail does not contain vertebrae. The original tail has a bony structure made up of vertebrae, which provide support and flexibility.

4. **Composition of the New Tail**: The regenerated tail is primarily made up of cartilage rather than bone. This means that while the lizard can regrow its tail, the new tail lacks the structural complexity of the original.

5. **Conclusion**: Therefore, the regenerated tail of the Wall Lizard is a cartilaginous structure that differs from the original tail, which had vertebrae. This adaptation highlights the lizard's ability to survive in the wild despite the loss of a significant body part.
