【養貓新手13】貓兒視覺的奧秘 Kiwidom Cat Blog

Cats have a different visual system than humans, which means they see colors differently. While humans have three types of cone cells in their retinas, cats only have two. This means that cats are dichromats, which means they can only see two colors: blue and yellow. They cannot see red or green.

The reason why cats cannot see red or green is because the cone cells in their retinas are not sensitive to these colors. The cone cells that are sensitive to red light are called L-cones, and the cone cells that are sensitive to green light are called M-cones. Cats do not have L-cones, so they cannot see red light. They also do not have very many M-cones, so they are not very sensitive to green light.

Despite their limited color vision, cats are still able to see quite well. They are able to see in low light conditions, and they are also able to see moving objects very well. This makes them well-suited for hunting in the wild.

Despite their limited color vision, cats are still able to see quite well. They are able to see in low light conditions, and they are also able to see moving objects very well. This makes them well-suited for hunting in the wild.

Cone Cells

Cone cells are specialized cells in the retina of the eye that are responsible for color vision. Humans have three types of cone cells: L-cones, M-cones, and S-cones. L-cones are sensitive to long wavelengths of light, which we perceive as red. M-cones are sensitive to medium wavelengths of light, which we perceive as green. S-cones are sensitive to short wavelengths of light, which we perceive as blue.

Cats only have two types of cone cells: S-cones and M-cones. This means that cats are dichromats, which means they can only see two colors: blue and yellow. Cats cannot see red or green because they do not have L-cones or very many M-cones.

The lack of cone cells in cats' retinas affects their ability to see color. Cats are not able to distinguish between red and green objects, and they may also have difficulty seeing objects in low light conditions.

Retina

The retina is a thin layer of tissue that lines the back of the eye. It contains specialized cells called photoreceptors, which are responsible for converting light into electrical signals that are then sent to the brain. There are two types of photoreceptors: rods and cones. Rods are sensitive to low levels of light and are responsible for vision in dim light conditions. Cones are responsible for color vision and are most active in bright light conditions.

Dichromats

Dichromats are individuals who have a deficiency in one or more types of cone cells in their retinas. This means that they are unable to perceive certain colors. The most common type of dichromatism is red-green color blindness, which is caused by a deficiency in the L-cones or M-cones. Dichromats who are missing L-cones are unable to see red light, while those who are missing M-cones are unable to see green light.

Cats are dichromats, which means that they can only see two colors: blue and yellow. This is because they have a deficiency in the L-cones in their retinas. As a result, cats are unable to see red or green light.

The fact that cats are dichromats has a number of implications for their behavior and ecology. For example, cats may have difficulty hunting in low light conditions because they are unable to see red or green prey. Additionally, cats may be more likely to be injured in traffic accidents because they are unable to see red traffic lights.

Blue

Blue is one of the two colors that cats can see. It is a primary color, and it is often associated with the sky, the ocean, and water. Blue is also a calming color, and it can be used to create a sense of peace and tranquility.

  • Wavelength and Perception

    Blue light has a shorter wavelength than red or green light. This means that it is more easily scattered by the atmosphere, which is why the sky appears blue. Cats' eyes are more sensitive to blue light than humans' eyes, which is why they can see blue objects more clearly.

  • Blue Objects in Nature

    There are many blue objects in nature, such as the sky, the ocean, and flowers. Cats are able to see these objects clearly, and they may be attracted to them. For example, cats often like to play with blue toys.

Low light vision

Cats are well-known for their ability to see in low light conditions. This is due to a number of factors, including the structure of their eyes and the types of photoreceptors they have in their retinas.

  • Retinal structure

    Cats' retinas have a higher density of rod cells than human retinas. Rod cells are more sensitive to low levels of light than cone cells, which are responsible for color vision. This gives cats an advantage in low light conditions.

  • Tapetum lucidum

    Cats also have a tapetum lucidum, which is a layer of cells behind the retina that reflects light back into the eye. This helps to increase the amount of light that reaches the photoreceptors, further enhancing their low light vision.

  • Large pupils

    Cats' pupils can open very wide, allowing more light to enter the eye. This is another adaptation that helps them to see better in low light conditions.

  • Behavioral adaptations

    In addition to their physical adaptations, cats also have a number of behavioral adaptations that help them to see better in low light conditions. For example, they are more likely to be active at dawn and dusk, when light levels are lower.

The combination of these factors gives cats excellent low light vision. This is an important adaptation for cats, as it allows them to hunt and navigate in low light conditions.

Motion detection

Cats are known for their exceptional ability to detect motion, which is closely related to their limited color vision. While cats can only see two colors, blue and yellow, they have a high concentration of rod cells in their retinas, making them highly sensitive to movement.

  • Visual acuity

    Despite their limited color vision, cats have excellent visual acuity, allowing them to detect even the slightest movements. This is due to the high density of rod cells in their retinas, which are responsible for low-light vision and motion detection.

  • Peripheral vision

    Cats also have a wide field of peripheral vision, allowing them to monitor a large area for potential prey or threats. This is particularly advantageous in low-light conditions, where their motion detection abilities are most pronounced.

  • Hunting behavior

    Cats' ability to detect motion is crucial for their hunting success. They can accurately track and pounce on prey, even in dimly lit environments, thanks to their keen motion detection capabilities.

  • Predator avoidance

    Motion detection also plays a vital role in predator avoidance. Cats can quickly identify and react to potential threats, such as other predators or approaching humans, allowing them to escape or defend themselves.

In conclusion, cats' limited color vision is compensated by their exceptional motion detection abilities. The high concentration of rod cells in their retinas, combined with their wide field of peripheral vision, allows them to excel in low-light conditions and effectively hunt, avoid predators, and navigate their environment.

Hunting

Cats are obligate carnivores, meaning that they must eat meat to survive. Hunting is an essential part of a cat's life, and their vision plays a crucial role in their ability to hunt successfully.

  • Color Vision

    While cats cannot see as many colors as humans, their dichromatic vision is well-suited for hunting. Cats are most sensitive to blue and yellow wavelengths of light, which are common colors in nature. This allows them to easily spot prey animals, even in low-light conditions.

  • Motion Detection

    Cats have excellent motion detection abilities, which are essential for hunting. Their eyes contain a high concentration of rod cells, which are sensitive to movement. This allows cats to detect even the slightest movements of prey, even in low-light conditions.

  • Depth Perception

    Cats have binocular vision, which gives them depth perception. This allows them to accurately judge the distance to prey, which is essential for a successful hunt.

  • Night Vision

    Cats have excellent night vision, which allows them to hunt in low-light conditions. Their eyes contain a layer of cells called the tapetum lucidum, which reflects light back into the retina. This allows cats to see in very dim light, giving them an advantage over their prey.

In conclusion, a cat's vision is perfectly adapted for hunting. Their dichromatic vision, excellent motion detection abilities, depth perception, and night vision all work together to give cats the advantage they need to be successful hunters.

Evolution

The evolution of cats' color vision is closely tied to their predatory lifestyle and the environmental pressures they have faced over millions of years. As obligate carnivores, cats rely heavily on their vision to hunt and survive. Their unique dichromatic vision, which allows them to see primarily blue and yellow wavelengths of light, is a result of evolutionary adaptations that have enhanced their hunting abilities.

Early cat species, such as the Miacis, possessed a broader range of color vision similar to primates. However, as cats evolved and became more specialized predators, their color vision underwent changes. The selective pressure to detect prey effectively in diverse lighting conditions, particularly at dawn and dusk, favored individuals with enhanced sensitivity to blue and yellow wavelengths. These wavelengths are commonly reflected by vegetation and the coats of small mammals, making them advantageous for hunting.

Over time, through natural selection, cats with superior dichromatic vision had a higher chance of survival and reproductive success. This gradually led to the loss of cone cells responsible for perceiving red and green wavelengths, resulting in the dichromatic vision observed in modern cats. This adaptation not only improved their hunting efficiency but also reduced energy expenditure, allowing them to conserve resources in their often challenging environments.

The connection between evolution and the color vision of cats highlights the remarkable interplay between an organism's sensory adaptations and its ecological niche. Cats' dichromatic vision is a testament to the power of evolution in shaping species to thrive in their specific environments.

Genetics

The genetics of cats play a crucial role in determining which colors they can see. The genes responsible for color vision are located on the X chromosome. Female cats have two X chromosomes, while male cats have only one. This means that female cats can be either homozygous or heterozygous for color vision genes, while male cats can only be hemizygous.

The gene for normal color vision is dominant, while the gene for dichromacy (the inability to see certain colors) is recessive. This means that a female cat only needs one copy of the normal gene to have normal color vision, while a male cat needs two copies of the normal gene. A female cat with one copy of the normal gene and one copy of the dichromacy gene will be a carrier for dichromacy, but she will have normal color vision herself.

The most common type of dichromacy in cats is red-green color blindness. This means that cats with red-green color blindness cannot distinguish between red and green objects. They may also have difficulty seeing shades of orange, brown, and yellow. Red-green color blindness is more common in male cats than in female cats.

The genetics of color vision in cats is a complex and fascinating topic. By understanding the role that genetics plays in color vision, we can better understand the behavior and ecology of cats.
