July 7, 2018 – Along this Caribbean reef, Pederson cleaner shrimp wait to feast on the parasites of these fish. A study shows that Pederson cleaner shrimp and fish signal to each other to initiate transactions. The fish will approach the shrimp holding their body very still. The shrimp then wave their antennae showing that they’re willing to clean. The fish will usually change to a darker color, a signal to the shrimp that there are no bad intentions. The shrimp will clean inside the gills, mouth, and other hard-to-reach areas. The shrimp gets a meal, and the fish stays healthy. It’s a win-win-fin.
