Answer

To answer the question about the bone of the shank in a frog, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Anatomy of Frogs**: Frogs are amphibians that have two types of limbs: forelimbs and hind limbs. The forelimbs are used for different functions compared to the hind limbs.

2. **Identify the Bones in Frogs**:
- The forelimbs consist of bones such as the humerus and radioulna.
- The hind limbs consist of bones such as the femur and tibiofibula.

3. **Focus on the Shank**: The shank refers to the part of the leg between the knee and the ankle. In frogs, this corresponds to the bones in the hind limbs.

4. **Determine the Correct Bone**: In frogs, the bone that corresponds to the shank is the tibiofibula. This bone is a fusion of the tibia and fibula, which are present in many other vertebrates.

5. **Conclusion**: Therefore, the bone of the shank in a frog is called the tibiofibula.

### Final Answer:
The bone of the shank in a frog is called the **tibiofibula**.
