Vandellia Cirrhosa

Apart from infesting other fish by attaching itself to the aortal arteries in fish’s gills, this parasitic pencil catfish is also able to infest humans who are fond of urinating underwater.

This tiny parasite targets red snappers by entering the fish and eventually ending up at the base of the victims’s tongue. Here, it digs until eventually the tongue falls off and is replaced by the parasite itself.

15

Trypanosoma

Triatomine Bugs

The Trypanosoma parasites are carried by the tritomid kissing bug (pictured above) and are released in the feces deposited on the skin of the host. The parasite then penetrates the host and disseminates throughout the body.

Cochliomyia Hominivorax

Cochliomyia Hominivorax
