This tiny but rather large-headed Japanese has one of the most oddly 
specific diets in the animal kingdom; its asymmetrical
 jaws are adapted 
for preying entirely upon snails…so long as their shells spiral 
clockwise. A once rare mutation is known to produce snails with 
counter-clockwise shells, and since these provide a greater challenge to
 the snakes, the “mirrored” snails may be growing steadily more common.
Atractaspis

The “stilleto” snake has also been called a “mole viper” and 
“burrowing asp.” Though highly venomous, it spends most of its time 
tunneling through soil with little or no room to open its jaws and 
strike. Instead, it possesses switchblade-like “pop out” fangs, which it
 hooks into subterranean prey by jerking its head backwards, hooking 
into their flesh.
Scolecophidians

“Blindsnakes” or “threadsnakes” are another group of burrowers, 
nonvenomous but quite a bit weirder than our last serpent. With eyes 
covered over by thin scales,tubular worm-like bodies and mouths tucked 
underneath their heads, these animals are completely adapted to a 
fossorial (burrowing) lifestyle, and feed primarily on soft subterranean
 insects such as termites and ant larvae. Some species even possess 
tiny, movable finger-like sensory growths on their snouts,much like a 
star-nosed mole.
 Eunectes murinus

No list of snakes is complete without the green anaconda, the 
heaviest alive today and one of the world’s longest predators. While 
their typical recorded length is up to sixteen feet, reports of 
anacondas over thirty feet in length have circulated for centuries. Like
 all constrictors, they wrap their bodies around prey to restrict 
breathing and kill by asphyxiation, swallowing the prey whole when it 
finally stops struggling.
 Naja ashei

With their deadly venom and famous “hooded” threat display, cobras 
are easily the world’s most iconic, most dramatized reptiles, and none 
are as fearsome as the various “spitting” cobras, who can spray venom 
several feet from their fangs with muscular contraction, often aiming 
deliberately for the eyes of attackers and capable of causing blindness.
 Naja ashei, a species from Kenya, is the largest and most venomous 
spitting cobra in the world, reaching lengths of up to nine feet from 
head to tail.
