River Monsters[]
Death Ray[]
Jeremy's first trip to the Mekong River in the series takes place in the episode "Death Ray." Jeremy visits to learn about the bizarre Giant Freshwater Stingray. He travels upriver to gather information, and then assists a team of scientists in catching a specimen.
Killer Snakehead[]
The second appearance is in "Killer Snakehead," where Jeremy investigates the native habitat of the Giant Snakehead after looking into reports of invasive Snakehead species in North America.
Mekong Mutilator[]
The river's final appearance in the series is in the episode "Mekong Mutilator," where Jeremy investigates brutal wounds caused by a mysterious beast. He eventually concludes that the culprit is the Freshwater Pufferfish, which inhabits the river in great numbers due to the fact that it is unsafe to consume unless prepared correctly. It also possesses a bite that could be as dangerous as a Piranha's.
