Chasing Monsters

After meeting a diver who was attacked by one, Cyril goes on a mission to catch a goliath `grouper', one of the world's largest fish, using a primitive and dangerous technique.

Recruited by researchers to catch the ocean's most feared predators and swab their razor sharp teeth to help develop antibiotics that save shark-bite victims, Cyril must brave crocodiles and raging sharks to fulfil this perilous mission.

Cyril sets out to catch a powerful catfish with only his hands, in Oklahoma's muddy waters.

On a mission to catch one of the largest freshwater fish in the world, in one of the most remote places on the planet, Cyril's survival skills are about to be tested.

Feared for its needle-like fangs, the alligator gar fish goes back more than 100 million years but has been hunted almost to extinction. Cyril is in Texas helping biologists learn how to reestablish the species, but to do so he has to get past some other snap-happy beasts.

Joining the Brazilian Military Police to put poachers behind bars is just the beginning of Cyril's mission - his real goal is to help protect Brazil's largest prehistoric fish, the endangered arapaima. To do it, he will have to wade through swamps infested with piranhas, caimans and anacondas, before facing one of the most epic fish battles ever seen on television.
