Give an example of parasitic adaptation in an animal.

Explanation

**Step-by-Step Solution:**

1. **Understanding Parasitic Adaptation**: Parasitic adaptation refers to the various modifications that parasites undergo to survive and thrive in their host organisms. These adaptations help them efficiently exploit their hosts for nutrients and reproduction.

2. **Identifying an Example**: One of the most well-known examples of a parasitic adaptation in animals is that of tapeworms.

3. **Locomotor Organ Loss**: Tapeworms have lost their locomotor organs. This adaptation is crucial because they do not need to move independently; instead, they attach themselves to the intestinal walls of their host, where they can absorb nutrients directly.
