Monster Fish: River Wolf

Published
Monster Fish: River Wolf
The wolf fish can reach 3 feet in length, weigh as much as 88 pounds and is said to be a brutal hunter — of animals and reportedly even humans. Little is known about this aggressive giant, so Dr. Zeb Hogan heads into the heart of Guyana to hunt for the biggest wolf fish he can find, to see if they deserve their fearsome reputation. To reel in the elusive predator, he'll have to navigate harsh terrain and carefully avoid heart-pounding encounters with anacondas, piranhas and vampire fish.
