Season 2, Episode 1, titled “Demon Fish,” features the goliath tigerfish, a creature that looks like it would be cast as a villain in the next “Finding Nemo” sequel. This freshwater fish can be found in Africa along the Congo River basin, which is exactly where Wade goes to find it (via Fishbase).
Prior to the series, Jeremy Wade actually traveled to the Congo region three times over a six-year period in search of the goliath tigerfish, which can weigh upwards of 100 pounds (via The Telegraph). Ultimately, he achieves his goal when he hooks a 78-pound tigerfish, a catch that Wade says is “the big one I had been after for almost 25 years.”
The fish is huge, splayed across Wade’s chest like a piece of armor, and its fearsome teeth rival that of a shark’s. Usually, Wade frees the fish after he catches them, but this particular specimen is given as a gift to the villagers who help the angler on his harrowing mission.
You can watch a variety of Animal Planet series on Discovery+, and you can read more about Wade’s exploits in his book “River Monsters: True Stories of the Ones that Didn’t Get Away.”
