Options

A. Aristotle
B. Linnaeus
C. Lamarck
D. John Ray

Answer

To answer the question "Who divided animals into Anaima (animals with no red blood, e.g., invertebrates) and Enaima (animals with red blood, e.g., vertebrates)?" we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Classification**: The question refers to the division of animals into two categories based on the presence or absence of red blood. The terms used are Anaima for animals without red blood (invertebrates) and Enaima for animals with red blood (vertebrates).

2. **Recall Historical Figures in Biology**: We need to think about historical figures in biology who contributed to the classification of animals. The options provided are Aristotle, Linnaeus, Lamarck, and John Ray.

3. **Examine Each Option**:
- **Aristotle**: He is known for his early classification of living organisms and indeed divided animals based on their blood. He categorized them into those with blood (Enaima) and those without blood (Anaima).
- **Linnaeus**: He developed the binomial nomenclature system for naming organisms but did not specifically categorize animals in the way described in the question.
- **Lamarck**: He is known for his theory of inheritance of acquired characteristics, not for classifying animals based on blood.
- **John Ray**: He contributed to the classification of plants and animals but did not use the terms Anaima and Enaima.

4. **Conclude the Correct Answer**: Based on the examination, the correct answer is Aristotle, as he is the one who divided animals into Anaima and Enaima.

### Final Answer:
The correct answer is **Aristotle**.
