vision question?

[NoOne]

Well look at tiger snakes on islands with gulls as the main prey, they ain't got no eyes, pecked out.
Most snakes don't have great long distance vision, in close they would be fine but they do relie on movement a bit.
I think most venemous snakes can only see about 3m, i been told that by a few people over the years, i've tried it on wild browns and they don't seem to have much vision outside 3-4m.

lol this is a good question.

there is no real everdence just how good a snakes vision is, as we cant see through there eyes as such.
but its beleived that their vision is rather poor. and if the prey sits still they cant tell what they are looking at . thats why they combine movment and taste and heat to identify whats good and whats not.
with your own snakes sit still when they are moving close to you. they will know you are there no doubt. but let them relax and start moving around there enclosure then you move watch the reaction you will get from your snake.
especally with snappy buggers even 3 feet away they cant see you untill you move.

my guess... you just lost ya carton of xxxx. your better off with out that stuff anyway..lol

cheers paul.

the eye sight of snakes ranges approx 3-5 metres clearly and then fades.
they rely mostly on their heat senses.

Where'd ya get that from Seth, I am of the exact same thoughts as Paul on this one

[luke]

there's nothing wrong with XXXX!

Eye wonder if BHP's and WOMAS have better vision than your more evolved pythons. With no heat pits, they might ? but then again elapids should be the same.....Paul this one's for you

XXXX SUXXXX!

hi ben

yeah we have offen wondered about that. but people seem to think that because there main diet is cold blooded animals that not having heat pits woudnt make there other scences more reactive..
but my thoughts are they allso eat mamals etc so they must be able to track this type of food scorse in some way.
i reacon that our bhps have better vision than the other animals we keep same goes for the womas as well.
just my thoughts.
cheers paul.

So what you're saying is
My BHP "looks" better than any heat pitted python..........hehehehhe

[Hawkeye]

Richard Shines book has an interesting piece on eyesight and it seems that the snakes of different species have different reliance on vision with dayhunting snakes being more dependant (and therefore having bigger eyes) than on vision. Blindsnakes have very small eyes and this is thought to be an evolutionary adaptation to having smaller risk reduced eyes when attacking ants and other bitey insects.

Another book I have also looks at the vision of Taipans and that they can actually look forward and there is a theory that they have some form of rudimentary binocular vision which allows them to judge the distance of their strike and being strike and release species this would be important.

So the end point is that some snakes have better vision than others dependant on their food type and hunting methods.

Cheers Hawkeye

PS: with the XXXX hows do they get the cat to balance while it is squatting over the can???

[africancichlidau]

And ya gotta listen to a man called Hawkeye when it's a vision question

[Bendragon]

But me thinks he's one of those VB drinkers we always hear about....
