Malagasy Leaf-Nosed Snake: This bizarre snake has a strange nasal appendage that is pointy in males and leaf-like in females. They use their snouts to camouflage themselves from predators and prey.
Flying Snake: These snakes don't rely on looks for their membership in the bizarre snakes' category; instead, they use the power of flight. They can glide through the air for stunning distances as much as 300 feet (100 meters).
Desert Horned Viper: These small snakes, never measuring more than two feet in length, have horns, which are modified scales, that are retractable. Scientists aren't sure of the horns' purpose, but they may help prevent sand buildup around the eyes.
Tentacled Snake: This aquatic snake is the only species in the world to possess twin "tentacles" on its snout. These tentacles are sensory organs that help them "see" in the murk and also lure unsuspecting fish.
Barbados Threadsnake: This threadsnake is the smallest snake species in the world. At only 4 inches long and about as wide as a spaghetti noodle, it may look more like a worm or grub.
Iridescent Shieldtail: The iridescent shieldtail, found in India's mountains, might be the world's most colorful serpent. A brilliant yellow stripe separates its iridescent back and belly.
Iwasaki's Snail-Eater: This snake is an even more specialized hunter than its name implies. Not only does it eat only snails, but due to its highly unusual asymmetric jaws, it is efficient only at feeding on snails with dextral (clockwise-coiled) shells.
Eastern Hognose Snake: This snake appears normal until it's threatened. Capable of flattening its neck to resemble a cobra, it will strike, but the strikes are pure bluffs; it doesn't bite, but merely "head butts." When that strategy doesn't work, the snake rolls on its back and plays dead.
