cleaner fish
Parasite-eating symbiont
Cleaner fish are species that remove parasites, dead skin, and mucus from larger fish.
The relationship benefits both parties—the cleaner gets food while the host gets groomed.
Cleaner fish establish stations on reefs where larger fish queue up and adopt submissive postures, even opening their mouths to let cleaners work inside.
Wrasses and cleaner shrimp are common examples.
