Do animals see in colour and do they have the full spectrum?

Question

Lol - to the dodgy fake Edna

Answer 1

There actually was an article about this very topic in the July issue of Scientific American.

Most mammals have only 2 colour receptors (I am Canadian, so I use the U sometimes), it is assumed that early mammals lost 2 (count them, 2!) unique photo-receptors types way back then because, as nocturnal creatures, they were not really useful. Then, one of the gene controlling the eye colour sensing cells got duplicated and mutated, reclaiming some of the lost capability. This is basically why we humans and most monkeys see a slightly more colourful world than most mammals, with cells for red, green and blue. This mutation of one gene probably explains colourblindness, I dare presume.


But birds (and reptiles) did keep all 4 (and I am jealous). They do see some UV light as well. They see more things than we can.
And most fish must also have that capability, although in their case, water is quickly muddling colour perception.

Answer 2

It depends on what particular animal it is. Also whether or not if it is a sea or land creature. It varies from species to species.

As far as I know, humans are the only creatures that can PRECEIVE the concept of the color spectrum.

Answer 3

<> Scientists did no longer "teach" this, seeing as they be responsive to it rather is unfaithful. Many animals have eyes that lack cone cells interior the retinas, and meaning they are in a position to't detect plenty assistance on hues. those animals ensue to incorporate cats and canines.

Answer 4

Animals do not see the full spectrum of colors; to them all is perceived in gray.

Answer 5

Dogs have the equivalent of one type of human red green colour blindness. It would be useful to them as it enables them to 'see through' camouflage and as they are carnivores they don't have to worry about eating the wrong colour poison berries ect.

Answer 6

It depends on the animal. Generally, "We see more colors than some animals, but some animals see colors we cannot". See link:

Answer 7

Depends on the animals. Some animals can't see certain colors, and neither can some humans who are color blind.

Answer 8

hmm thats a good question as far as i know dogs can only see in black and white but im not sure for all other animals

Answer 9

i dont know the color stuff of all animals, but i know that cats cant see the full spectrum of color but they see amber and green exceptionally well

Answer 10

dogs see in b/ and white only but my dog sluggo told me last tuesday that he picks up a little blue now and then
