Mantis Shrimp

Called "sea grasshoppers" by ancient Assyrian , "prawn killers" in Australia and now sometimes referred to as "thumb splitters" by modern divers — because of the relative ease the creature has in mutilating small appendages — mantis shrimp sport powerful claws that they use to attack and kill prey by spearing, stunning or dismemberment. Mantis shrimp can break through aquarium glass with a single strike from this weapon.

Chinese Paddlefish

One of the largest freshwater fish, it is said that the Chinese Paddlefish can grow to 23 feet and weigh 1,100 pounds, but little research on a maximum size can be conducted today due to the species' scarcity. Due to overfishing, the Chinese Paddlefish is endangered now and quite possibly extinct.

Goliath Tigerfish

" One of the most fearsome predators freshwater has ever known, the Tigerfish has a viscious reputation. These fish hunt in large packs, just as their South American counterparts, the Piranhas do. Prey consist primarily of other fish, but just about anything alive can fall prey to the Tigerfish. Like the Piranha, prey is eaten away bite by bite. Because they have razor sharp knife-like teeth, and extremely strong jaw muscles, they are among the few fish that can turn the tables on prey the same size or larger than themselves. There are unverified reports of attacks on humans."
