Answer

To answer the question about the diaphragm found in crocodiles, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of a Diaphragm**:
- In mammals, the diaphragm is a muscular structure that separates the thoracic cavity from the abdominal cavity and plays a crucial role in respiration.

2. **Identify the Type of Diaphragm in Crocodiles**:
- Unlike mammals, crocodiles possess a diaphragm that is not muscular. This indicates that their diaphragm functions differently compared to that of mammals.

3. **Determine the Characteristics of the Crocodile Diaphragm**:
- The diaphragm in crocodiles is described as being well-developed but non-muscular. It separates the lung cavity from the rest of the body cavity.

4. **Classify the Diaphragm**:
- Given that the diaphragm in crocodiles does not fully separate the thoracic cavity from the abdominal cavity in the same way that a muscular diaphragm does in mammals, it is classified as "incomplete."

5. **Conclude the Answer**:
- Therefore, the diaphragm found in crocodiles is classified as "incomplete."

### Final Answer:
The diaphragm found in crocodiles is incomplete.
