The terrifying PIOJO EAT LANGUAGE

In Science Daily Online we have delved into other times in the world of parasites , like the amoeba that devours the human brain.Among the parasitic animals, the one that occupies us in this article is perhaps one of those more amazing and terrifying .It is known as the "louse eats tongue" , although its official name is Cymothoa exigua and, fortunately, Your hosts are the fish .

The terrifying LICE EAT LANGUAGE

The "louse eats tongue" is actually a crustacean isopod quite widespread in our oceans.Currently a subspecies the «cerathotoa italica» is spreading through the Mediterranean waters .It does not cause no harm to humans , except the scare of seeing it inside the mouth of the fish you just bought.It's the only parasite that can replace a part of your host with total success .It seems that the fish does not even know that has lost its tongue since the "louse eats tongue" does its functions.

How do you parasite the fish host? It does so very easily because penetrates from the gills to the oral cavity .There adheres to the tongue and drinks the blood directly from the artery that goes to it.In the end, the tongue dries out and falls apart, when the parasite takes advantage of it to take its place and continue living fish while serving as a tongue.The fish is weakening and shortens its life expectancy.

The terrifying PIOJO EAT LANGUAGE

The" louse "has another peculiarity that makes it, if possible, more interesting. Change sex ! Start being a male so that, at the time of mating, if there is not a female nearby and only another male, change one of the two of gender . Mating takes place in the gills and it is the female that parasites the fish .It lays its eggs on the host's tongue and the tiny crustaceans that will be born from them, will come out of the fish's mouth in search of new specimens to parasitize.This ability to change gender is absolutely necessary since almost all new "lice eat tongue" will be male.

The terrifying PIOJO EAT LANGUAGE

It usually happens more often in fish of deep sea fishing than in those of low or farmed fish and it is very difficult for you to find one in the fish that you buy, since by its size it is easily detectable and in the markets they will eliminate them.We repeat that does not represent any kind of threat for human health.
