Which animal has the best eyesight? - Thomas W. Cronin

Explore the incredible diversity of eyes and vision in the animal kingdom, and find out which creature has the best eyesight.

--

The animal kingdom boasts an incredible diversity of eyes. Some rotate independently while others have squiggly-shaped pupils. Some have protective lids, others squirt blood. But which creature has the best sight? Which sees best in the darkness? Which sees the most detail? Which animal sees the most color? And finally, which detects motion the fastest? Thomas W. Cronin investigates.

Glad they went with a 'best in categories' rather than just 'best overall' : D

As Lord ZeFrank said, "Try to imagine a color that you cannot imagine. This is how a mantis shrimp do."

Imagine being able to see peoples’ body heat or see an ant crawling up a tree from 600 feet away. That’d be trippy.

Another awesome video on eyes. I really like these comparison videos of human traits against the animal kingdom. Top notch animation as always! 🤌

[KitKatWiffleBallBat]

Have I mentioned how much I love and appreciate this channel? You guys make me a better, smarter person with your clean cut presentations and smooth delivery of information.

Thank you for all your hard work.

The Animation as always..was a " Sight " to behold 🙂

In others words, the human eyes is a jack of all trades, but a master of none.

Edit: before you want to comment about the rest of the quote ("but better than a master of one"), please read the others comments so you will know that 40 people already said the same as you. I got it already. So did everyone else.

The music is so haunting, calming and beautiful! Thank you TedEd!

The reason for the color change in reindeer eyes is because during the winter, its pupil remains permanently dilated, causing increased pressure in the eye that compresses the structure of the tapetum lucidum. The constant pressure squeezes fluid out between the tapetum lucidum's collagen fibers, and they become more tightly packed. The spacing causes the reflection of shorter wavelengths, hence the blue color. In the summer, the pressure is relieved and the eye reflects a yellow to green wavelength.

The music is so pretty on this one! My admiration to the sound team!

Lovely, just lovely….

What a beautiful animation style! Ted-Ed is absolutely brilliant

[Pixintendo]

Many times I imagine what it would be like if a person’s entire retina were like a macula. We can’t even imagine, because if we could see perfectly with the whole retina, which zone would our brain be paying attention to? The one thing is that our vision, even in such a limited version, requires a lot of capacity for the brain, so I can’t even imagine seeing it sharply in every corner.

I think this animation is your best yet. Colorful, precise, elegant, smooth. A masterpiece.

[alienume]

This channel is the greatest thing that happened to me! I am someone who tends to question soo many things in this crazy world, and often get weird looks for that. But this channel has awnsered the even most bizarre things ever, which i might have never thought of asking nor thinking of! I love learning new things and this channel has been feeding me with information every single time. Keep up the great work :)

[chengyiq]

The animation, combined with the background music, makes everything seems so at peace & calm

[Nonchalant.is_da_one]

It has been like what 9 years and this man's voice still hasn't changed one bit... That's true dedication to a channel

[lovely-yjzy]

Thank you Ted Ed for making videos that contain a lot of information.

[letsgetreal]

Love this topic, as well as all your videos on it. Really interesting to know about the huge spectrum of visual perception across species! Humans may not be the best, but we can rank decently in everything, and that may have given us a surprising advantage.
Hats off to the animation, as usual!

[angelaliu]

Never really noticed until this video, but the background music fits the topic very well! Awesome job Ted-Ed, *see* you next time XD
