 | | Rarely, in the Amazon, members of the genus Vandellia (and perhaps a few closely related species in other genera) accidently enter the urethra, vagina, or rectal orifices of humans. |
 | | The species most commonly reported as intraurethral is Vandellia cirrhosa ("candiru," "carnero," "canero,", or "vampire catfish"). |
 | | The exact reason why this fish might accidently enter a body orifice is unknown, although the presence of ammonia or urea in the water has been a popular hypothesis. |
