It is also famous for swimming into people when they go for a wee in water! It is thought that the candiru mistakes the flow of urine for the flow of water from a fish's gill. They swim up the stream of urine and into the human (male or female).

Once a male finds a female, he physically attaches himself to her. Some older females can have several males attached at the same time. Many of the males internal organs break down and they actually become part of the female, even using her blood supply. When the female releases her eggs the male is right there to fertilise them. So far scientists have discovered 149 different species of angler in the abyss.<\/p><p><a href=\"#top\" onclick=\"showFact()\">Done<\/a><\/p>"
