Scenario:
Cleaner shrimp is the name given to shrimp that clean other organisms of parasites, which are tiny harmful animals. These shrimp live on coral reefs throughout the oceans. Cleaner shrimp hang out in sections of the coral reef and wait for fish to approach to be cleaned, similar to a car wash station. With no hesitation or fear of being eaten, the cleaner shrimp enters the mouth of the larger fish and vacuums up parasites and dead
cells. Cleaner shrimp go wherever they want, even through the delicate gills of larger fish, to pry out the parasites. The larger fish get cleaned, sanitized, and groomed, and become healthier from this service. The cleaner shrimp get fed.

And give Evidence and Reasoning.
