Cleaning station for Titan triggerfish
In this video we show you a particular form of mutualistic symbiosis, quite widespread in the marine aquatic environment, between a Labroides dimidiatus cleaner fish and a Titan Triggerfish. The cleaning operations constitute a mode of relationship in which the cleaner fish feeds on the ectoparasites, on the now dead skin tissue flaps and on the food residues of the host, which undergoes its care. The "customer", i.e. the fish being cleaned, gains a better fit of its body, while the cleaner gains nourishment.
