Do hippos see in color? If so what colors?

Yes, we see very bright, vivid, swirling tie-dye techni-colors. Oh, wait a minute, I thought you said Hippies. Sorry : )

OK, Blackie, I'm guessing you mean 'hypnotized' not hippatized,  as I have no idea what hippatized means.   No, I can't be and neither can you.  Most owls stare.  That's just because they don't blink as often as we do and really are watching for their prey.

all the time! Usually i see just the light reflectiong off their wings cause they move so fast! It's a good sign if you do see them. kinda lucky.

The colouration may not make as much sense on land, when they are waddling about, but in the sea as they 'fly' through the water in search of fish and squid and other yummies, it is actually a highly effective form of camouflage.\n\nCalled counter-shading, it makes them pale from below, blending into the brighter background of the surface, and dark from above, blending into the stygian blackness of the abyssal depths.\n\nA lesser form of counter-shading is common in many terrestrial critters as well, where belly fur is often paler than the pelage on the dorsal surface.  Dogs, kitties, even squirrels and bunnies often show this same pattern.\n\nIn the watery environs of a pelagic predator, it is even more effective due to the greater degree of contrast in the environment, and the lack of effective cover in which to hide.  \n\nCounter-shading can be seen in critters like sharks, dolphins, swordfish,  and tuna.\n\nHere's a picture of a tuna showing counter-shading http://www.panamafishingandcatching.com/tuna/preultimo-tuna-tunalarge.jpg\n\nAnd one of a shark http://na.nefsc.noaa.gov/sharks/img/27.jpg\n\nProbably the best examples of counter-shading would be the orca (aka killer whale), and the manta ray.  Like penguins, they are very distinctly black on the back and white underneath.\n\nManta ray http://www.no-pest.com/MantaRay.jpg\n\nOrca http://orca-voyance.auraciel.com/orque2a.jpg

There is no ONE kind of animal.... several species can see color to some extent and it is difficult to prove since animals can not tell us!!\n\nHowever go to this link and it will describe many animals that can see color to some extent.\nhttp://webexhibits.org/causesofcolor/17.html\nsome even better than humans (pigeons and mantis shrimp!)

Mammals don't see colors the way we do, for example it may be impossible to train them to choose one of two colors to get a food reward.  Insects often see UV light, which we don't, so two red flowers that look exactly the same to us could look 'great' due to UV markings and 'boring' due to no UV markings to an insect.

If you are asking if other animals are concerned with how they look your answer is "of course". Think of any kind of male trying to attract a mate (peacock being an excellent example!). They try to have the biggest tails, brightest colors, or whatever will give them the best mate. if you are asking whether or not they can recognize themselves in the mirror, some apes can since they are so intelligent but so-called "lower mammals" cannot since they lack the brain capacity.

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).

Birds and reptiles have better color vision than humans\nMost mammals have poor color vision by human standards.\nPrimates have vision like humans.\n\nColor vision arises from photoreceptor cells in the eye called cones. \n\nBirds and reptiles have four different kinds that are sensitive to four different wavelength ranges. Most mammals have only two types having lost half somewhere in the distant past due to mutations. Most of the mammals that lived in the shadow of the dinosaurs were nocturnal, so color vision wasn't very useful to them anyway.\n\nPrimates have the same two kinds of cones that mammals, birds and reptiles have in common, but unlike other mammals they have a third type which is unique to primates, it arose via a mutation and allows human style color vision. It's sort of an awkward compromise when compared with birds and reptiles though. They can see UV light, we cant'\n\nI'd add that any nocturnal animal regardless is less likely to have good color vision, because overall light intensity is sensed by a different kind of photoreceptor cell (rods) and good night vision requires more rods than cones. You can't have your cake and eat it too.\n\nI don't know much about fish and amphibians. \n\nSome insects have very good color vision in tems of color perception. Any of the ones that co-evolved with flowering plants would see color better than usb ecause of that extended spectrum thing. Although the specifics of their vision systems aren't familiar to me.\n\nI only know the stuff on bird, mammal and primate vision because of an article in a recent issue of Scientific American.

There's a peak absorbance of rods and cones in the retina.  Humans have three peaks which represent the primary colors (for light) red, green, and blue.  The colors we see are our brain's interpretation of input on those three colors plus general light level input from rods.  Based on the numbers of rods and cones and the absorbance spectra of the different cones, researches can get an idea of the color vision of different animals.\n\nMost mammals are dichromatic (two colors).  Note how non-colorful they tend to be.  Certain primates are trichromatic (three colors).  Birds, reptiles, amphibians, and insects are also trichromatic or more.  Note how colorful they tend to be.

Good question!\n\nNature has evolved molecules that pigment various parts of organisms.  Plants and flowers are the obvious case in point, but in humans, skin pigments, and those in the iris (giving us blue, green brown etc. eyes) have also evolved.\n\nIt is QUITE POSSIBLE that at some point in the past, alternative pigmentation DID evolve in humans, and the only thing we CAN say with any certainty, is that if it did, if was later eradicated from the gene pool, and does not ersist any longer.\n\nMost notably, the only ANIMALS that have evolved the colours you mention have been birds, where the ability to fly away rather than the need to camoflage and blend in is the preferred means of evading redators.  So bright colours in these cases are NOT dangerous to the organism (bird) displaying them.\n\nIt is true that some other apes (primates) DO display bright colours.  Some have bright red backsides, and in some cases, bright blue pigment is evident on parts of the bodies.\n\nSo as a final thought:  in a world where bright colouring is no longer likely to be life endangering to humans, how long will it be before a random genetic mutation causes pigmentation other than the standard tan and browns that we are used to to evolve?!

The MOUNTAIN Hippo?  I'm fairly sure there isn't one. Double check just to be sure.

It's just a color.\n\n\nMaybe they are color blind

Yes, hippos do have vocal cords and a larynx.  They produce a number of sounds, mostly grunts, squeals and roars.

According to this website deer can see some color, and their vision is at least as clear as ours!\nhttp://www.bowhunting.net/artman/publish/NolanAtskoGlowvid.shtml

umm... giraffes are not green... maybe you were looking at some other animal..\n\n\njust so you will believe me... here's a picture of a giraffe!\n\n\nhttp://www.nilesafaris.com/images/giraffe1.jpg

I'm sure if you gave a Hippo some chocolate pudding, they would gobble it up with no problem.\n\nAs far as their preference......well you know as well as I do that you may never get a true answer to that.....\n\nOne thing I do know for sure........this was a cute question and it really made me laugh.\n\nThanx for the chuckle!\n\n:)\nPeace!
