Answer

To solve the question of which animal group has the highest percentage of endangered species, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which animal group has the highest percentage of endangered species. Endangered species are those that are at risk of extinction.

2. **Identify the Animal Groups**: The common animal groups to consider are insects, mammals, amphibians, and reptiles.

3. **Analyze Each Group**:
- **Insects**: Insects are highly diverse and numerous, making them less likely to face extinction as a group.
- **Mammals**: Mammals have a good adaptation to various environments. The percentage of endangered mammals is around 20-23%.
- **Amphibians**: Amphibians are particularly vulnerable due to their dual habitat (both aquatic and terrestrial). Approximately 32% of amphibian species are considered endangered.
- **Reptiles**: Reptiles do not have as high a percentage of endangered species compared to amphibians.

4. **Compare Percentages**: From the analysis:
- Insects: Low percentage of endangered species
- Mammals: 20-23% endangered
- Amphibians: 32% endangered
- Reptiles: Lower than amphibians

5. **Conclusion**: Based on the percentages, amphibians have the highest percentage of endangered species at 32%.

### Final Answer:
The animal group with the highest percentage of endangered species is **Amphibians**.
