In Felids the vertical slit is only found on the smaller ones. Its better for spotting prey in grasses. The larger ones have pretty much the same eyesight as we humans have if you added the reflective membrane for night sight.

7:53 Jumping spiders (Salticidae) have amazing vision (for spiders). Not only do they see clear color images, but they can also see ultraviolet and polarized light.
Some wolf spiders (Lycosidae) have been observed to use light polarization to navigate.
Most other spiders have limited vision. They rely more on tactile and chemical cues. (Orbweavers can essentially “hear” through their webs!)

The inverted retina is likely just evolution optimizing what happens to be there more so than an advantage. Flipping retina would not make evolutionary sense unless the organism revolved the entire eye, you cannot have a slightly “flipped” eye be an advantage, so it is an evolutionary dead end.

This was a great video, and in no way am i trying to discredit or downplay his obvious expertise. However, he states that dogs don’t have color vision, which is not true. They are dichromatic, so while they don’t have the ability to see as many colors as us, they can still see colors such as yellow, green, and blue. Again, I’m not trying to attack the video or the expert, but that statement just rubbed me the wrong way. Regardless, it was still a great video.

A thing to note in some compound eyes like that of the dragonfly in the video, is that in the centre of it is an actual dark mass, which creates the optical illusion of pupils always looking right at you. Hence why in all the scenes or photos there’s this “stare” If you get the chance to play with a mantis or see a dragonfly: try bobbing your own head around and notice how the optical illusion “follows your every move”

31:50 The height of the cat definitely does not correlate with the eye shape. A perfect example is what’s likely the lowest-slung cat around, the pallas cat.
What is far more likely is the nocturnal cats have slit pupils for more range while the diurnal cats have round pupils for more clarity in bright light.

Thank you for this video. But The light that hit the retina doesn’t form image. There is no vision in eyes. The brain has no vision image. The image is actually in the mind and reflects in the movement. So vision is in the body and mind. The eyes and brain are optical and neurological media. Food for your thoughts!

The Eye is connected to the brain and dependent upon the brain to interpret what we see. The cells in the Retina absorb and convert the light to electrochemical impulses which are transferred along the Optic Nerve, a bundle of more than a million nerve fibers, carrying visual messages to the Brain.
Evolutionist want to pretend that unguided, undirected chance created these masterful components and connections through some environmental requirement of improvement and survival. What a joke!
Evolution, mutations and natural selection have no foresight to an end result, yet somehow, without intelligent involvement, a system for sophisticated sight being processed by the species brain is developed.
Even more miraculously, it independently duplicates a symmetrically mirrored system, positioned proportionally on the other side of the nose.
Simply AMAZING and stupid logical reasoning, if not for Intelligent Design of a Creator.

Excellent line of research which I’ve often thought about –
I think the vertical slit on smaller cats is due to being weary of animals that can fly – vertical animals. Lions aren’t going to be weary of bird species, because birds are (mostly) small and really a large part of their diet, or their prey.
Small cats have vertical slits when in low light, but oval/circular when dilated. My contention is this – Because small cats should be “concerned” about larger birds they evolved eyes that have a special acuity for species that can move in the vertical dimension.
This makes sense.
Not just because birds (etc.) are prey, but also because larger birds are predators to cats as well. They should be much more attentive to vertical movement than large cats. It makes evolutionary sense.
it makes a lot of sense that in smaller cats they have more acuity for the vertical, whereas larger cats don’t actually need this. It’s a waste for large cats, but for smaller cats, it’s basically essential to be very capable of resolving vertical movement in other animals that might be prey/predators.
Right?
It should be researches more.
I’d imagine smaller dog species would have had the same kind of eyes, but they’re all extinct now so we don’t have the comparison (so maybe they didn’t, and the birds just wiped them out before the could evolve like small cats – but this is pure speculation).
Right?
I aware that other small predators dot have this ability. So maybe look into those species natural habitats as compared to small cats.
I don’t have time.
I wrote a paper on this in college as a teenager.
I’m not sure that I’ve seen anyone else speculate about this idea.
If anyone reads this and takes inspiration? You’re welcome – all the best! Good luck.
I’m a chemist now so I’m out! You’re welcome. Though it would be nice if someone does go down this path to say “credit – some guy on YouTube called thunder chunky!” 😂

@ISplimeI

12:39 One thing about the dragonfly section is that the picture that you showed was actually of a damselfly (Zygoptera). The taxonomy shown (Anisoptera) is actually an infraorder, which is dragonflies, but if you wanted to include damselflies as well, step back two links in the phylogenetic tree to the order Odonata, which includes damselflies and dragonflies. I’m pretty sure that their vision is quite similar, with dragonflies having slightly better optical range since their eyes cover their entire heads, so it’s not a big issue, just wanted to let you know. Overall, this is an incredible video, especially since animal vision is always such an amazing concept. The fact that evolution allows for some of these complex structures to exist is fascinating.

@briseboy
April 16, 2025 at 2:18 pm
What was interesting about studyig some jumping spiders, is that they appear to infer that comparatively extremely huge humans, are regarded as life to be wary of .
As a jumping spider passes through exposed terrain, it will turn its entire body to repeatedly scan th eobserver for signs of change, then move, and again, repeat the turning of its body to warily again eye the monster human.
Of course, we understand that they use memory beyond that of mre sensory, CHOOSING to pass through areas invisible to prey, rather than expose themselves. They stalk, as do conceled predators who use ambushtactics.
This, then, is holding memory for at least the short term.
Very likely, learning over time variabilities. Theory of Mind.

I have Professor Schmitz for one of my classes at Claremont McKenna! He’s an excellent teacher in class as well and helps us grasp complex topics. So happy to see him on WIRED

I’m sorry. When you bring up jumping spiders, I’m going to have to go away for a while to watch some jumping spiders.

Strepsiptera eyes? Only learnt of them recently, a shame they weren’t covered here. I was also hoping to hear more of the evolutional relationship between the different eyes, maybe too much for one video though. A good introduction to the variety possible in nature.

I think the jumping spiders have some of the most interesting eyes in the animal kingdom. Veritasium has great video on it, I recommend everyone watch it for a fascinating lesson on their eyes. With a fraction of the size of an eye, they manage to see as well as us, just in a cone of vision reduced to about 10°.

It amazes me that my pet lizard can see twice as many colors as I can. He sees fer red and ultraviolet. I wish I could see what his world looks like to him.

Am I ignorant to think squid pupils are shaped oddly to counter how the sun/light travels through water and how they can disguise themselves or change colors? I can’t imagine they don’t see color….

Great video. Thank yopu. Too bad you did not include mantis shrimp. Their eyes are something else.

I’ve thought about this so much.
It’s really fascinating to me that so many different eyes in the animal kingdom are almost universal in at least basic design and function.

that’s why some bugs with compound eyes fly into lights at night…

I wanna see colors at night! I have a gecko I didn’t know she could do that, so cool.

Wired, improve the explanatory graphic visuals in your channel videos, I see the visual and editing of Howtown channel videos are very impressive.
