Amazon Flesh Eaters

"A man swallowed whole by a fish. A body eaten alive from within. Another penetrated in a most unnatural fashion, and yet more with multiple stab wounds. Jeremy is in pursuit of these notorious killers to discover the facts - to determine if their crimes are real and their methods as gruesome as reported."

Synopsis
Following a report of a fisherman swallowed whole, Jeremy travels to South America in search of the Amazon's largest catfish, the piraíba. Arriving there, Wade not only tries to catch this monster, but discovers that it belongs to a whole family of Amazonian killers. He catches as many catfish species as he can to prove that these whiskered predators really are the ultimate monsters of this place.

His mission is to try and catch the three largest catfishes until he encounters with the smallest ones. He finds the candiru, a tiny blood-sucking catfish that has entered a man's body in the most horrifying of places, and the candiru-acú, a catfish that swarms around and drills holes in dead or dying animals, including humans, eating them from the inside out and leaving only the skin and bones.

Discovering the horrifying deeds of these fish only pushes him even further, until he faces off with the giant head of the murderous catfish family, 'the mother of all catfishes', the piraíba.
