'A Symbiotic Relationship' by Liang Fu
A cleaning station is like a mutual symbiotic community underwater. Every individual living in the community benefits from the others. The grouper and moray eel have their dead skin, bacteria, and parasites cleaned by the shrimps and wrasse, while at the same time the cleaner species receive nutrients and protection from the fishes.
I have spent years studying the symbiotic behaviour between shrimps and different fish underwater. The photos I took are from different locations, showing a lively mutual symbiosis relationship.
