Biologist Jeremy Wade has been reeling in some of the biggest fish around the world on Animal Planet's River Monsters. The informative series follows Wade as he searches the world's rivers for answers to terrifying fatalities and deadly creature incidents.
Some of Wade's impressive discoveries include frightening vampire fish, venomous jellyfish, and stingrays that can drag a person to their doom.
And beware: you may never want to set foot in a body of water again.
Wade investigated the attacks and believed the fish developed a liking for human flesh after eating bodies that were disposed in the rivers during funerals.
Giant Bull Shark
Host Jeremy Wade's biggest freshwater catch ever, the giant African bull shark weighs close to 500 pounds.
The nearly 10-foot monster took 2 1/2 hours to reel in with a fishing line. The bull shark is responsible for many attacks on humans and can swim in freshwater rivers and other subtropical locations.
The African lungfish is an ancient creature that can reach over six feet long. The fish normally swims along the water's surface, often burying itself under the sand to hide from prey.
The slimy fish can breathe both in and out of the water, and it can often be heard belching when sucking in air.
