do all the animals see in color?

Question

aside from cats, what other animals don't see in color?
do all animals see in color?

Answer 1

Birds and reptiles have better color vision than humans
Most mammals have poor color vision by human standards.
Primates have vision like humans.

Color vision arises from photoreceptor cells in the eye called cones.

Birds 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.

Primates 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'

I'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.

I don't know much about fish and amphibians.

Some 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.

I only know the stuff on bird, mammal and primate vision because of an article in a recent issue of Scientific American.

Answer 2

Most animals do not see in color

Answer 3

Many people have always wondered if animals can see in color. Tests have been done and a lot of time has been spent doing research.

Although a lot of people think animals can only see in black and white, dogs and cats can see two colors but weakly. Some small mammals like squirrels can only see in blues and yellows. Primates (apes and chimps) can see the same colors we can. Also African monkeys can see the same way we do. Even though most other primates can see all the colors we do, South American monkeys can’t see red very well. All birds can see five to seven colors.

Cephalopods like octopi and squids can only see blue. A crayfish (type of crustacean) can only see blue and red. Most fish can see only see two colors. Amphibians, animals that live in and out of water like frogs, can see most colors.

Most of the animals that can see in color can see the same colors humans do. However, some animals see even more colors than that. Reptiles like snakes can see some of the colors humans do, and they can also see infrared rays. Infrared rays are invisible light rays beyond the red end of the colors visible to man. Spiders can see green and ultraviolet rays. Some insects like bees can see blue, yellow, and ultraviolet rays. Ultraviolet rays are light rays beyond the violet end of the color spectrum. People cannot see infrared rays or ultraviolet rays.

These are just some of the many animals that can see in color.

ANIMALS AND THE COLORS THEY SEE
• SPIDERS (jumping spiders) - ULTRAVIOLET AND GREEN
• INSECTS (bees) - ULTRAVIOLET, BLUE, YELLOW
• CRUSTACEANS (crayfish) - BLUE AND RED
• CEPHALOPODS (octopi and squids) - BLUE ONLY
• FISH - MOST SEE JUST TWO COLORS
• AMPHIBIANS (frogs) - MOST SEE SOME COLOR
• REPTILES (snakes) - SOME COLOR AND INFRARED
• BIRDS - FIVE TO SEVEN COLORS
• MAMMALS (cats) - TWO COLORS BUT WEAKLY
• MAMMALS (dogs) - TWO COLORS BUT WEAKLY
• MAMMALS (squirrel) - BLUES AND YELLOWS
• MAMMALS (primates-apes and chimps) - SAME AS HUMANS
• MAMMALS (African monkeys) - SAME AS HUMANS
• MAMMALS (South American monkeys) - CAN'T SEE RED WELL

Answer 4

well bats can't see they use hearing and I'm sure MANY other animals can't see color. I'm not really sure. My uncle is an animal researcher so I'll ask him and get back to you!

Answer 5

no, most animals don't see in color.

Answer 6

No, dogs see in black and white. Cats do see in colour! don't know about other animals though...

Answer 7

No. Horses do not see in color. But they sure can put away the hay!

Answer 8

no not all animals see in color...dogs don't see in color either, check out an animal encyclopedia :)

Answer 9

I THINK ALL ANIMALS SEE COLOR

Answer 10

Dogs don't see in color. I don't believe sharks do either.
