The majority of snakes have a wide field vision of 125 degrees,however most pythons such as afrocks have 135 degrees. They also have binocular vision, which allows them to appreciate distance and perceive depth. This is due to an overlap of the field vision of the left and the right eye. This overlap normally averages 30 % However in the genus Ahaetulla it is about 45 %.

Snakes have round or vertically slit pupils. The only exceptions are the genera Ahaetulla, Thelotornis and Dryophiops. In these snakes the pupils are horizontally slit and formed like a keyhole. The so shaped pupil has the slot of the keyhole pointing forward well beyond the lens, thereby creating an extensive lenseless space. During accommodation the lens moves not only forward, but also more strongly nasally than in other snakes .

This is supported by a groove between eye and tip of the snout, which serves to widen the ankle towards the middle.
So the genus Ahaetulla is that with the best distance appreciation of all snake genera.
The members of all of the genera with horizontally slit eyes are diurnal and arboreal. They are ambushers, which means, they sit and wait until suitable food crosses their way. They normally feed on lizards, a very fast moving food. So these anatomically features seem to be adoptions to the nutrition and environment: The snakes have to hunt fast moving, dayactive lizards, that are living in a three dimensional space.

Also many snakes' species lack the ability to focus by changing shape of the lens. Instead they move the lens back and forward as a camera. This allows for limited focusing ability.

fact:
snakes are awesome! this measure of awesomeness can't be measured using standard awesomeness units, so they've had to come up with a whole new scale (pun not intended originally, but what the heck).

other uses for this new scale of awesomeness was measuring the awesomeness of Chuck Norris (who is nearly as awesome as snakes, but not quite). Arnold, however, came out in a tie with them.

Fact: This is a scale NOT used to measure Ray Mears

DEFINITION OF RESEARCH

In the broadest sense of the word, the definition of research includes any gathering of data, information and facts for the advancement of knowledge.

corrct me if i'm wrong but isn't this what she is doing? and we all know how conflicting the internet can be for good facts.

Forget Harry Potter ....this shit has just made for a much more exciting read!! Plenty of drama and abuse!! BBC Three tackle.. (yes I have read the Harry Potter books but in fairness to me it was whilst being held at gun point by a group of angry children who some of whom I now suspect were elderly midgets wearing very convincing masks)

The fastest snake is said to be the black mamba


reticulated pythons - are the known longest snake at about 23.5-24ft(actual proof and not exaggerations or bull) This was something that i have been researching for years and with all the information that i could find i could not find any proof of a big snake over 25ft. They are the jack of all trades being able to climb and swim and have been seen far out at sea.

Green anacondas- Are the heaviest in comparison to any snake at the same length and are able to bite from behind. In breeding several males can try mate with the female at once and there are actually rarely any fights at all between males when this takes place. They have the largest sexual dimorphism of any species.

Green anacondas cannot strike from behind? You would be right if you had stated that anacondas are the only snake that can strike side ways but your loop the loop striking theory is wrong. This evolution probably has something to do with the perception of prey from underwater...who knows : victory:

people are just so bitchy nowadays :)

some ae the more primitive snakes, like pythons n boas still have the vestiges of a pelvic girdle as part ae their skeleton, and have small claws/spurs which are believed to be remnants of hind legs which were lost after god punished mr snakey to crawl on his belly for all his days....or evolution....whichever one is the truth
