do moose eyes glow in the dark?

no, you see the reflection of light in their eyes.

I believe such an animal the term low-light vision is used. Such as an owl. Most birds are sight-driven and have excellent vision. The owl has excellent day vision and excellent night vision because its pupils can dialte to allow moonlight or starlight sufficient lighting to see by. This is not to be confused with infravision which is totally different than low-light vision. That would allow the heat an animal gives off to be seen in the dark.

No, it's an LED. Some mice have lasers (Logitech MX1000) but you can't see the beam. Put down your mouse.

why don't you tell us if the moose used a condom on you..........my guess is he didn't and you liked it!

Oh, yes.  Many insects can perceive ultraviolet light; and birds have 4 photoreceptor cells in their eyes (we only have 3) so they can also see some ultraviolet.\n\nThe rumors that animals can only see in black and white is wrong, by the way.  Most mammals have only 2 color receptors so they see things less colorfully than we do -- it seems evolution determined that early mammals, being nocturnal animals, did not need all 4 photoreceptors their ancestors did, and lot them.  Very recently -- in evolutionary terms, that means just a few tens of million of years -- the monkey/ape reacquired some of the color sensitivity by having one of the color cell type mutate and differentiate, so we now have 3; but in some cases, the DNA is not foolproof, hence we have color blindness.\n\nThere was an article about this topic in the July 2006 issue of Scientific American, a bit of this is available on the attached link.

Your eyes were glowing because they are white, anything white will glow under black light. Your teeth were probably glowing too. I'm an eye doctor, I can assure you its nothing to worry about.

It all depends on what environment they live in. There are nocturnal (night) animals that see very well at nightime. Birds of prey (eagles, hawks, falcons) have great eyesight for when they are high in the sky. Octopi have great eyes for being underwater. SO, it all depends on where they are.

They are primarily out during the day. I believe they rely on sight to forage for food so the daylight would probably be quite helpful.

Wolf spiders \n\nWolf spiders hunt at night. Usually brown and black, they may have longitudinal stripes. Wolf spiders are large and often seen under lights. They can be seen at night when their eyes reflect light from a flashlight, headlamp or car headlight. \n\nYeah, they get that big, and they tend to chase you if you run from them.  I have heard one spit or hiss, I did not stick around long enough to determine what the noise was.

There are two basic differences.\nThe main one is the number of rods at the back of the eye. These minute rods are very sensitive to light. Nocturnal animals have many more of these than humans.\nThe second reason is that nocturnal animals can open their pupil to a much greater extent and so let in more light.\nThe quote below refers to owls but is just as valid for animals.\n\n"The eyes themselves are modified in nocturnal species to improve sensitivity in low light intensities. This is achieved by several adaptations; they are very large, a Snowy Owl weighs as much as our own, secondly they are tubular rather than round giving a relatively large cornea in proportion to the overall size of the eye which enables more light to enter the eye. The light passes through the pupil, (which can be closed by the iris to a small pinprick in bright light, or, opened so wide that virtually no iris is visible at night) to the lens. This is large and convex causing the image to be focused nearer to the lens hence retaining maximum brightness. One draw back is that owls are long sighted and cannot focus on objects, which are to close, tactile bristles around the beak partially compensate for this. The tubular shape also gives a comparatively large retina size which is packed full of light sensitive rods, about 56,000/ square mm. in the Tawny Owl. These rods are far more sensitive than cones at low light levels The phenomenal light gathering properties of the owls eye is further enhanced in many species by a reflective layer behind the retina called the tapetum lucidum reflects back onto the rods any light that may have passed through the retina without hitting one the first time. Tawny owls would appear to have the best developed eyes of all the owls, indeed of all vertebrates, being probably about 100 times more sensitive at low light levels than our own. To put this into perspective, a Tawny Owl can locate prey several metres away by the light of just one candle about 1700 feet away!"

I do not think so.  I believe the Mooses are an American phenomenon.

Most lemurs have pretty poor eyesight in a general sense, showing better acuity at night than in the day.  For survival, they rely much more on social calls, for which they are well-known.  They react strongly to shadows on the ground near them, rather than actual birds in the sky.  I'm having trouble getting exact measurements on how far and exactly how well they see, though.\n\n(I hope it's not too late!)

Not all lizards anyway.\n\nThe nocturnal helmeted gecko has become the first vertebrate known to see colours in the dark\nTHE nocturnal helmeted gecko has become the first vertebrate known to see colours in the dark. \n\nMost creatures, including humans, have eyes that contain two types of light-sensitive cells. In daylight, animals rely mainly on colour-sensing cones that distinguish between light of different wavelengths. At night, when photons are scarce, they rely exclusively on more sensitive rod cells, which are colour-blind. \n\nThe only exception to this rule, and the only animal known to see colours at night, was thought to be the elephant hawkmoth (Deilephila elpenor). It has adaptations, which include different facets of its compound eye, to increase the light captured by its cone cells in the dark (New Scientist, 2 November 2002, p 23).

Not likely. He probably saw a white tail that was a little dark. Blacktail are strictly a Pacific Northwest deer.\n\nWhitetails are Odocoileus virginianus\nhttp://www.mnh2.si.edu/education/mna/image_info.cfm?species_id=231\n\nIt is easier to tell them apart by the antlers than the tail color. Blacktail and muleys have a main antler beam that goes up then branches. Whitetails have a main antler beam that goes forward and the tines go up. \n\nSome animal lists don't even include the Blacktail. They say that they are a subspecies of Mule Deer. \nOdocoileus hemionus\nhttp://www.mnh2.si.edu/education/mna/image_info.cfm?species_id=229\n\n\nThis link tells you more than you will ever need to know about blackies.\nhttp://www.blacktailcountry.com/html/blkpage.htm\n\nIn the field, I can't actually tell the difference between mule deer and blacktails, but I think the horns hanging in my garage are blacktail.\n\nKeep your muzzle in a safe direction!\nLeigh M\nhttp://www.NWSafe.org

they come out at night, mostly
