                  Cleaning stations are remarkable evolutionary developments. 
                  Large fish will congregate in "safe zones" to permit smaller 
                  cleaner fish and shrimp to scour their bodies for parasites 
                  and algae. The cleaners will often enter the mouths of their 
                  "clients" without risk. Such mutually beneficial associations 
                  are commonplace on coral reefs.  |
