71. Candiru

73. 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)
