The small blue fish, a wrasse, represents a symbiotic relationship in the sea. They are the local car wash. Fish have no fingers to clean themselves. So the wrasse hang about. Some call their locations ‘cleaning stations.’ Bigger fish come along and the little guys do their task. I’ve seen them within the jaws of moray eels. Hmmm a tasty morsel, just swallow. But larger fish even seek out the wrasse. And there seems to be an unwritten agreement about not eating your cleaning service help. Do fish have ears? None that stick out. Because it is hard to clean behind your ears in the sea?
