Demon Fish Goliath Tiger fish! Invincible giant soldier

When your name is Goliath, you'd better be one humongous, ferocious creature, and the Goliath tigerfish (Hydrocynus goliath) definitely lives up to its moniker. A native of the Congo River basin, the Lualaba River, Lake Upemba, and Lake Tanganyika in Africa, it's the largest member of the tigerfish clan, a genus of fierce predators with protruding, daggerlike teeth. The biggest one on record was nearly 5 feet long and weighed 154 pounds, the equivalent of a super-welterweight prizefighter. And it outclasses other African game fish in speed and power.

Locals say it's the only fish that doesn't fear the crocodile and that it actually eats smaller ones. It's also been known to attack humans in rare instances. It's so lightning quick and forceful that not only will it snap an angler's line, but it will sometimes make off with his or her tackle. No wonder one fishing safari promoter requires clients to read a cautionary treatise on the Goliath before agreeing to a fishing trip.
