Good Question think it's because of the predator prey relationships. Like rabbits are colorblind, because they only eat grass and occasional bugs. Cats need color to see the birds and mice and others to distinguish their food source. Like the coral snakes. An animal that is prey to it has color to see their predator.
Bears, like most mammals, have some color vision. There is some indication that they can see reds, which many mammals cannot see, and if this is true, then their color vision is similar to that of a human being. There is a source like below.
All mammals except primates can only see the colors green and blue.
No, typically mice are not blind. They have relatively well-developed vision and use it to navigate their surroundings, locate food, and communicate with others.
No, but most mammals see only in black and white.
No they can see many colors, but they can not see the color red.
No, cats are not color blind like dogs. They can see some colors, but their color vision is not as strong as that of humans.
Yes, but they can't see all the colors we see. Mammals, other than primates (humans are primates), are red/green color blind.
Yes you always see color but it might not be the right color
No they can see color
Yes, cats and dogs are not completely color blind, but they do not see colors as vividly as humans do. They can see some colors, but their vision is limited compared to humans.
I looked a lot of places and I could only find a few animal that are not color blind. -cats -rats -mice -cows -sheep -human -ratlesnakes -hores (horses are part colorblind.They do see colos just just not the range of colors that us, humans see today.) Hope that helped!<3 (:
Most mammals, such as dogs and cats, are believed to be colorblind and see the world mainly in shades of gray. However, some research suggests that certain animals, like monkeys and apes, have the ability to see some colors.
