The story is that the fish swims up a stream of urine into a man's penis, then eats it from the inside. But is there any truth to it? Of all the denizens of the Amazon basin, there is none more feared than the tiny fish known as the candiru.
Suddenly you feel it. Also known as the toothpick or vampire fish, this little river monster has swum up your penis and lodged itself in position using its umbrella like spines. The candiru Vandellia cirrhosa is a tiny catfish measuring just 3 to 5 cm in length.
Among the many legends of strange, dangerous creatures that haunt the Amazon, the story of the Candiru fish stands out. The Candiru fish Vandellia cirrhosa is a small catfish purported to enter the, ahem, intimate orifices of unfortunate people who urinate into Amazonian waterways. Supposedly, the fish mistakes urine for water expelled from the gills of marine life.
The candiru became the most famous catfish in the world inwhen an icthyologist read a medical report about a man who had to have this toothpick-shaped fish removed from his urethra. The truth of the claim has always been in dispute, but people have feared peeing in the Amazon river ever since. They needn't have been afraid. Researchers couldn't test whether one candiru had got itself stuck inside one man, but they could test the notion that candiru were urine-seeking missiles.
This fish is called the candiru and is a member of the genus Vandellia. The candiru is found in the Amazon region of South America and is a type of catfish. The fish is actually parasitic.

These smaller species are known for an alleged tendency to invade and parasitise the human urethra ; however, despite ethnological reports dating back to the late 19th century,  the first documented case of the removal of a candiru from a human urethra did not occur untiland even that incident has remained a matter of controversy.
