River Monsters (Seasons 1–9)

River Monsters (2009) is a British documentary series you can watch online on iFILM. Biologist and extreme angler Jeremy Wade travels to remote rivers across the globe — the Congo, the Amazon, the Mekong — tracking fish that local communities blame for attacks on swimmers and fishermen.

Each episode works as a standalone investigation: Wade interviews witnesses, pieces together evidence, and eventually drops a line in water that most people avoid. The underwater footage gets uncomfortably close to some very large and aggressive fish. Worth watching if you want to understand what actually lurks in freshwater — and why those river legends keep coming back. Stream River Monsters online on iFILM.
