do animals see in colour?


Answers:
Many animals can see things that we cannot. For example, cats can see at night when it is too dark for us. However, we do not know what animals actually perceive. There is an important difference between merely having light illuminate our retina, and actually understanding what we are seeing.

The role of color vision in an animal's perception, behavior, and ecological setting, and its underlying retina and neuronal mechanisms vary enormously in different groups of animals. Although color as a perceptual category with cognitive significance obviously plays a great role in human life, there is, with the exception of hymenopterous insects, still little evidence about the roles of color perception in nonhuman animals, especially nonprimates. Current research finds that color vision in non-primate mammals is very limited, and probably bears little resemblance to humans'. Nevertheless, it is proven that animals see some form of color vision.
yup.
does a bull charge at the color red?
I could be wrong, but I believe they are color blind.
yes they do
Some do, some don't and others see in shades
i don't think so
How else are they supposed to appreciate my colorful ensemble!
some do, some dont, cats see in black and white(and can tell what things are based on the different shades. It depends on the animal.
They have now decided, with new technology, that they do. But not the same as we do. They see less colors, and mostly less vivid colors. They see more shades of black %26 white because it helps them detect movement better - which is important for survival, as a hunter or the hunted.
Yes. I do.
Yes but not in the same way that you do, unless you are blind then they will have slightly better colour vision than you
yes and no
I imagine some do.
dogs dont
no the do not
of course they do. ignore the so called 'experts' unless of course, they have four legs:-)
i think that dogs see in black %26white and maybe some floresent colors like bright green
I know some, like dogs, are definitely color blind. I think all of them look more for motion than for color to spot something that they care about.
Hi ,,, not that I know of.

good luck
Dogs see in black and white- cats see in color. I imagine there are a lot of other animals the same way.
Have a great day!
dogs see in black and white!
Snakes if going by that new movie out(yawn) , snakes can't really see in color-bit of black,green. Who knows!
Some yes, some don't, some parcially. For sure I can say that cats, horses and bulls are colorblind. It's not the color red that enrages the bull in the corrida, it's the movement of the fabric. ;)
Many fish can see colors (e.g. Phoxinus, Crenilabrus). Some amphibians can see colors (frog: Rana temporaria, toads: Bufo bufo, some salamanders) and they usually have two pigments. Most reptiles can see colors (snakes, turtles). Birds: general rule: birds that are active during the day can see colors, but birds that are acitve during the night cannot. Mammals are generally bad in color vision. Examples of color-blind mammals are rats, hamsters, rabbits, and dogs. Cats are weak, but can see some colors. Mammals that are quite good are guinea pigs, sheep, zebra, horses.
I think that they do see some colors, my cat loves Clifford the Big Red Dog, even if the volume is muted she watches him during the whole show! I would like to think that all fuzzy babies can see at least some things in color.
I believe they do. For years they have said that they dont but they are full of it. My dog hates the color orange. Only the color orange. Once he jumped out of the car when we were going down the road doing about 25 mph, just to attack an orange barrel. He wasnt hurt real bad the little idiot, but he lost a toenail and had a few scrapes.
most animals can see in colour, it is dependant on how their brains interpret what they see?
most mammals have eyes that can see colour and dogs can be trained to recognise object by colour but mammals eyes sight is mainly designed to respond to movement rather than colour.

No, animals see in black and white (or at least not the full range of color humans see)
However they can Smell and Hear in color ( having a much greater range in both of these senses)
Well they say they dont, but how would they know? The great thing is..they DO see everything, when youre happy, when youre sad, some of them watch TV, some dont. They know when youre angry, when youre fighting. They are smarter than ppl give them credit for. Some of them are smarter than humans. As long as they CAN see, thats all that matters.
