Dogs and horses are colored blind
Improved Answer:
Actually, dogs can see some colour! They can pick up yellow and blue-purple colours as they have two cone types which allows them to see in limited colour. Horses also can see in blue and yellow as well. There are only a few animals that cannot see in any colour at all: Seals, sea lions, walrus' and animals from the Cetaceafamily (whales, dolphins and porpoises) have only one cone type (which is called being Monochromatic).
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.
Most mammals have at least limited color differentiation ability, but three color vision only exists in other primatives like monkeys :D)Dogs have 2 coloured vision birds have much better sophisticated colour vision than mammals. So no , not all animals are colour blind :)
Both. Dogs are dichromats, like most mammals, and have vision similar to red-green color blindness in humans.
That depends on exactly how you define the term.Humans are trichromats: our eyes contain color receptors that are sensitive to three different spectral bands.In "color blind" people, there's something wrong with one or more of these types of color receptors.Most mammals are thought to have only two types of color receptors. This doesn't make them completely insensitive to color, but it does give them a type of color blindness.Sea mammals appear to only have one type of color receptor, meaning they can only distinguish between colors based on their brightness.
yes
No, but most mammals see only in black and white.
All mammals except primates can only see the colors green and blue.
Yes. They are color blind. :)
No they can see many colors, but they can not see the color red.
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.
The olm (''Proteus anguinus'') is a blind newt (sslamander) that lives in caves. The mole is another blind creature. It uses its nose instead and lives nice and deep down under the Earth.
The only other group of mammals that is able to distinguish colors is the cat family. Several animals are color blind, or see in black and white.?æ
