Chasing Monsters - Season 3

Mysterious disappearances, brutal attacks, wounded people leaving trails of blood. Can a ruthless predator fish with razor-sharp teeth like the piranha, with its reputation as a true man eater, really be responsible? To answer this question, Cyril must survive deep in the Amazon jungle as he chases down the biggest piranha out there: the mythical black piranha.

An electric eel can emit a devastating, 700-volt shock to kill its prey. But is this enough to kill a human, like locals in the amazon say it is? Although these eels are part of countless myths and legends, much about them is still unknown. In order to study and understand this mysterious creature, Cyril has been given the dangerous task of catching and handling the shocking beast.

On the rio Parana in northern Argentina, countless fishermen have been violently pulled into the water by unidentified creatures and some have even mysteriously disappeared - Cyril ventures deeper and deeper into caiman and piranha-filled swamps to investigate these disappearances and to answer one question: what beast could possibly be strong enough to drag a fisherman into the water?

Cyril's attention is captured by videos of two huge, unidentified creatures appearing off of Florida's coast - and discovering what these monsters are becomes an obsession. Is it even a fish? The list of possibilities is long and Cyril knows that the only way to truly identify the beast is to explore the mysterious waters here, and try to catch it.

Every year, hundreds of wildlife attacks and accidents occur in the pristine waters of the paradise, sunshine state of Florida. In this episode, Cyril attempts to understand why marine predators, like barracudas and sharks, attack humans, and figure out the factors that can trigger this unexpected and devastating aggression.

Guyana's jungle in South America is wild and untamed, a remote no-man's land patrolled by jaguars, and where gold diggers still look for a bounty. And deep in the jungle rivers here lives one of the most powerful fish in the world: the brutal Pirarara.
