Autotomy is recorded in

Options

A. legs in crabs
B. Tail of lizards
C. Viscera in holothurian echinoderms
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Autotomy**:
- Autotomy refers to the spontaneous removal or shedding of a body part by an organism. This process is also known as self-amputation and typically occurs when the organism is injured or under threat.

2. **Analyzing the Options**:
- **Option 1: Legs in Crabs**:
- Crabs can shed their legs as a defense mechanism when they are attacked. This is a well-documented example of autotomy.
- **Option 2: Tail of Lizards**:
- Lizards are known to drop their tails when threatened or injured. This is another clear case of autotomy.
- **Option 3: Viscera in Holothurian Echinoderms**:
- Holothurian echinoderms, commonly known as sea cucumbers, can expel their internal organs (a process called evisceration) as a defense mechanism. This is also a form of autotomy.
- **Option 4: All of the Above**:
- Since all the previous options (legs of crabs, tails of lizards, and viscera of sea cucumbers) are examples of autotomy, this option is correct.

3. **Conclusion**:
- Based on the analysis of the options, autotomy is recorded in all of the mentioned organisms. Therefore, the correct answer is **All of the Above**.

**Final Answer**: Autotomy is recorded in all of the above organisms.
