CLEANING WORKERS OF THE SEAS
What occurs to you if you see a small fish that is about to enter the mouth
of a big fish? You think that the big fish will swallow the small fish, and you
wonder why the small fish comes so close to it.
It is undoubtedly unusual that the big fish lets the small fish swim around
it, does not attack it and does not care about its swimming in its mouth or
through its gills. It is, however, possible to see such scenes a lot in the
oceans. It is not only some small fish that fearlessly swim around big fish.
Sometimes shrimps, too, may be seen near the mouths of big fish. These are
cleaner shrimps whose job is to clean some big fish.
