Answer

To determine the lifespan of the crocodile and mayfly, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Lifespan of the Crocodile**:
- Crocodiles have a long lifespan, typically ranging from 60 to 100 years.
- For example, the saltwater crocodile has an average lifespan of about 70 years, while the Nile crocodile can live up to 100 years.

2. **Identify the Lifespan of the Mayfly**:
- In contrast, mayflies have a very short lifespan, often living only for about 1 day.
- This brief lifespan is characteristic of their life cycle, where they spend most of their lives in the nymph stage underwater.

3. **Combine the Lifespans**:
- Based on the information gathered, we can summarize that the lifespan of a crocodile is generally between 60 to 100 years, and the lifespan of a mayfly is 1 day.

4. **Select the Correct Option**:
- When looking at the provided options, we need to find the one that matches our findings.
- The correct option is 60 years for the crocodile and 1 day for the mayfly, which corresponds to option 4.

### Final Answer:
The lifespan of the crocodile and mayfly is respectively **60 years and 1 day**.
