are snakes blind?

Answer 1

No they are not, even though they can't blink due to lack of eyelids and cannot swivel their eyes around in their sockets. If someone tells you they "see with their tongues" or just use their heat pits for sensing, they're only half right. While pit vipers use their heat pits when there isn't enough light to see, hence the name "pit" viper, they still use their eyes out in the daylight. And as for tongues, that's how they smell, not see. (but there are certain burrowing snakes that are blind, but I assumed you were talking of the above-ground variety)

Answer 2

Most snakes see very well. And some snakes do have heat sensors and can use that to find prey as well. The only time their vision is impaired is when they are close to shedding when the scale over the eyes becomes hazed. Snakes also detect smell by collecting scent particles out of the air with their tongue and bringing it to an organ in their mouths called a Jacobson's organ. Their forked tongue helps them detect the direction the smell is coming from. One thing that they can't do is hear air born sounds. They have no external ears. What they can do is detect vibrations from the ground. The vibrations are picked up by the bones in their head and carried to an internal hearing system. That's why you could scream all day at a snake and not get a reaction. But tapping the ground near the snake will make them react. That also explains the cell phone thing the other person mentioned. Although that really doesn't have anything to do with their vision.

Answer 3

Snakes Blind

Answer 4

Depends on the type of snake none are truly blind some have poor vision, some have great vision it depends on the species, those that have poor vision or are nocturnal use heat sensers, or mostly their jacobsons organs which are taste receptors at the back of their throat, they basically stick their tongue out and smell and taste the air, it is so sensitive that they can pick up molecules of their pray in the near vicinity, all snakes have that ability as some lizards, but diurnal (daytime) snakes have exceptional vision. Hope that Helped

Answer 5

They've got eyes, don't they? And they don't sense heat with their tongue, like someone said. Snakes see pretty well, but the aerboreal ones see better, with more vivid colors. Some (actually, most) snakes have heat pits. Those snakes can see infrared images with the heat pits, but not all can. Snakes taste the air with their tongue, and then stick the tongue into the Jacobson's organ in the roof of their mouth. They can taste the very chemicals in the air this way. Snakes can smell sweat, water, most things. You can even see cats do something like this. When cats smell something interesting, they'll open their mouths a bit and curl their tongue so that it touches the roof of their mouth. Snakes can sense WHERE a mouse is in the same way, but they can't actually see an image of a mouse with their tongue.

Answer 6

OK wow... i haven't seen this much mis information in a long time.. if you dont know the answer then dont respond to the F***ING QUESTION!!!!

on a side note,

only a select few see with heat sensing pits most species of snakes do not.

yes they see.

no they dont use there tongue to see heat.

yes snakes can move there eyes in there sockets.... just look at the eyes of a retic and you will see that for yourself.

Answer 7

No they most deffinatly are not. In order to catch their food they use their Jacobsons orgon whitch is their sense of taste, their heat sensors and their eyes. One of our snakes will track a person moving across the room. The only time their vision is impared is when they are in shed, at this time they can only see movemet and shadow.

Answer 8

Absolutely not. They can see well. Most are nocturnal hunters. At night they see via heat sensors and eyes combined. They smell with their tongue and all combined they are a hunting machine. I have 4 snakes.

Answer 9

No. Snakes sense with their tongues. They sense body heat. So when they sense the heat with their tongue, they see the infrared shape of the object that the heat is coming from.

Answer 10

Nope... they even see infrared, or the warmth of objects
