Humans as we know we are able to see everything almost perfectly in this world, like the colors, shapes, etc. But do you know how differently some animals and insects see you? Read the article to know how!
1. Human vs dog/cat.
Humans have three types of receptors in eyes, which help them to see all kinds of colours by combining the Red, Blue, and Green colour. On the other hand, dogs and cats have only two receptors (blue and yellow).
2. Human vs bird
While humans have three receptors, birds have four. The fourth one enables them to view an ultraviolet spectrum which makes them a tetrachromat.
3. Human vs rattlesnake
A rattlesnake can see few colours but it has the ability to see infrared. The sensors are located on their heads.
4. Human vs cephlapod
The cephalopod includes creatures like octopus, squid, nautilus, etc. which have evolved from vertebrates. They are totally colour blind. They have three photoreceptors. One enables them to see some shades of gray. The other two receptors help them to detect polarisation which human eyes can’t. By nature, they have the ability to avoid ultraviolet rays. Humans have to wear sunglasses to reduce UV impact.
5. Human vs bees
Bees have only two receptors, blue and green. They have the ability to see UV light patterns. Bees feed on the nectar (a sugary fluid secreted by flowers) of flowers and with the ability to see UV light; it becomes easier for them to spot patterns of nectar on a flower.
6. Human vs scarab beetle
These organisms reflect a circular polarised light off their back which the humans are unable to see. Scientists believe that they reflect this particular kind of light to communicate.
7. Human vs bats
Studies have shown that bats can see a polarized light. Primarily, they just use echolocation to navigate through and to capture their prey. Well, for us we certainly can see all the colours but bats have the advantage of echolocation. Echolocation is the use of sound waves and echoes to determine the location of objects in space.
8. Human vs butterfly
Being able to see red, blue, and green; butterflies can see UV and the wide band light ranging from red to purple. Still, they have only 0.04 vision when compared to humans which can’t let them see a coin put at a distance of 50 centimeters.
