Description

The candiru, (Vandellia cirrhosa), is a scaleless, parasitic catfish of the family Trichomycteridae found in the Amazon River region. It is translucent and eellike, and it grows to a length of about 2.5 cm (1 inch). The candiru feeds on blood and is commonly found in the gill cavities of other fishes. It sometimes also attacks humans and has been known to enter the urethras of bathers and swimming animals. Once in the passage, it erects the short spines on its gill covers and may thereby cause inflammation, hemorrhage, and even death to the victim.
