Give me specifically four interesting facts about the symbiotic relationship of cleaner shrimp and marine fish.

1. Cleaning symbiosis: Cleaner shrimp and marine fish have a unique mutualistic symbiotic relationship wherein the shrimp act as cleaning stations for fish. The shrimp remove parasites, dead skin, and other unwanted materials from the fish's body, helping them stay healthy and free from infections.

2. Shrimp's advertisement behavior: Cleaner shrimp have an interesting behavior called "advertising" their services to attract fish clients. They wave their long antennae and perform an enticing dance-like motion to catch the attention of fish. This behavior helps create a partnership by signaling that they are ready to perform cleaning services.

3. Fish's trust: Despite the shrimp's sharp pincers, the fish fully trust the shrimp not to bite or harm them during the cleaning process. This level of trust is established through specific touching motions that both the fish and shrimp perform, signifying the acceptance of the cleaning procedure.

4. Diversity in clients: Cleaner shrimp have a vast clientele of fish species. They are known to clean a variety of marine fish, irrespective of size or aggression levels. Even large predatory fish that could potentially eat the shrimp show no aggression towards them while being cleaned, indicating the trust and value of the symbiotic relationship.
