Candiru
Vampire fish, Candiru, (Vandellia cirrhosa)
•Slender, nearly transparent, a few centimeters in length
•Can burrow through the body wall of fish and have been
found in the body cavity.
•Parasitic, entering the gill chambers of larger fish, erecting
a series of spines to hold them into place, and feeding off
blood from the gill filaments for a minute or two
•Rarely, in the Amazon, Vandellia accidentally enter the
urethra of humans urinating in the water. Even more rarely,
the anus and vagina have been reported to serve as suitable
orifices. Apparently, the urine is mistaken for urea given off
in low quantity by fish gills.
•Surgical removal of the catfish is necessary. (1973, Urology
1: 265-267)
