Fact or Fiction? The Urethra Invading Fish:

The Amazon Basin harbors an amazing amount of biodiversity. Freshwater dolphins, bull sharks, vicious piranha, mammoth anacondas, and a myriad of other species all call the Amazon River home. Covering some 7 million square kilometers (2.7 million square miles), it is the largest drainage basin in the world. When talking about length, the river itself is regarded as the second longest river in the world (it is second only to the Nile), so it"s not too surprising that so many species call this water "home.”

The list of dangerous animals that resided here is quite extensive, but not every animal that is dangerous to humans is large in stature. In this case, the tiny creature is a small parasitic catfish that has a tendency to find its way into an orifice of a larger organism in order to suck its blood – sometimes, these larger organisms are humans. Meet one of the most surprising fish in the world, the Candiru.
