How do our snakes see the world?
I've read that some snakes see in fuzzy B&W, where as others can see a bit more sharply with some colour...
Do any of your corns/rat snakes have issues with seeing? Aparrently the burrowing type of snakes have poor vision yet ours seem to notice anything and everything!
I know this is a random thing but I've just been thinking about it and now I want to know! |

I have shined a bright pin point of light into Spot vivarium and he followed the dot of light, he absolutely could see it and was interested in it, i've done this with the Boa who is absolutely mesmerised by moving light.
I love watching their eyes and they move around opening and closing the pupil and also focusing on things so I do believe their vision is actually very good. Some better than others as my Boa will respond to the sight of me from across a room but with the corn I need to be a bit closer.
Oh and corn snakes do not have the ability to 'see' heat. Most Boas can and most Pythons have very obvious heat pits on their nose.
good post that, with regards to heat, pythons and some boas can, specifically emerald tree boas, cooks and amazon, i think thats about it, probably other tree boas i dont know about.
Others include rattlesnakes and other pit vipers.
Their ability to sense heat is very sensitive, certainly with rattle snakes they can detect about 1/1000 of a degree change.
This does not apply in any way shape or form to cornsnakes, they cannot sense heat in the slightest. |

All is interesting! And we all love a nerd, without them we'd not have this info! |

I don't think snakes on a plane is anything to go by at all!
I've heard some snakes can detect heat but i'm not sure this appliesto corns
Not sure about that, mine certainly see a warm fuzzie far quicker than one that has gone cold. |

I'd figured that much, lol.
I just find it mad how nobodt knows for certain how they see, yet can tell us how things such as flies can! |

I know that some reps can see into the UVA spectrum, so I think their colour vision is shifted slightly to the left (smaller wavelengths)... Whether this applies to corns or not I dont know |

I don't think anyone actually knows. would be interesting to find out though.
Corns aren't natural burrowers there is one snake, I think it's just called the Blind snake.. lives 99.9% of it's life underground a bit like a mole though.
