Praying mantises get fitted with 3D glasses, watch bug movies
CNET ^ | 01/08/2016 | Eric Mack

Yes, that's right. Scientists actually outfitted the odd insects with tiny 3D glasses to confirm that they actually see and hunt in 3D vision. I've been staring at the below picture for a while now of the green and blue lenses affixed to a praying mantis' head with beeswax and I still can't decide if it's cute or creepy.

Researchers have suspected for years that mantises see in 3D, but scientists from Newcastle University in the U.K. finally hit on the right design of glasses for the insects.

The idea is the same as the old-school red and blue polarized glasses used at 3D movies, but the researchers used green instead of red because the bugs see that color much better. After being fitted with their new custom specs, the creepy-crawly subjects were shown short videos of tasty bugs in 3D, and they struck out at them. When shown the same images in 2D, they didn't go for the bait. (Let's face it, given their habit of decapitating mates, praying mantises probably like their entertainment big.)

...

"Despite their minute brains, mantises are sophisticated visual hunters which can capture prey with terrifying efficiency. We can learn a lot by studying how they perceive the world," Jenny Read, a professor or vision science and leader of the study, said in a release. "Better understanding of their simpler processing systems helps us understand how 3D vision evolved, and could lead to possib"e new algorithms for 3D depth perception in computers."

The smallest insect alive, after for billing years of evolution, is more wonderful than anything created by man. There is a lot that we can learn from their biological systems.

Did the mantis say “these glasses don’t go with anything?”

The study also revealed the ones with glasses were picked on and called names like bug eyes by the mantises without glasses.

I’m not sure this makes sense.

All sight is 3-D.

As written it is essentially saying praying mantises hunt by sight.

Was there an argument that they used smell or other senses to hunt?

I think they aren’t so much studying the Mantis eyesight as they are trying to see how the mantis brain processes projected 3d images from a computer.

Mantises with glasses never get passes.

Thousands of years. I don’t buy into “we all came from scum” evolution.

Do they still chew the heads off their mates?

They called him “forty-thousand eyes.”

If you gaze at a distant object, each eye sees pretty much the same image. If you look at an object within reach, then each eye sees the object from a different perspective.

Your brain is able to detect these differences and has learned how to judge the distance to a near object.

The mantis study claims to have demonstrated that the insect will basically ignore an object which might otherwise be considered food if the object seems to be at a great distance. However, if the mantis detects that the object is within reach, then it will attempt to catch it.

Mantises are cool.

Someone posited that they might be alien visitors, they are so different from other bugs.

Only ISIS mantises do that.

Always good to see them in a vegetable garden.

Clever. Probably don’t get eaten too.

Please tell me no tax dollars were harmed in the making of this study.

I do not think that evolution and God are incompatible. God is infinite and why wouldn’t he make a universe that, by its very design, leads inevitably to the creation of life everywhere that inevitably evolves to higher forms of life with intelligence, beauty, the capacity to love, and having a soul?

When God said “Let there be light” why cannot that be said to be the Big Bang?

Genesis 1:3

1. In the beginning God created the heaven and the earth. 2And the earth was without form, and void; and darkness [was] upon the face of the deep. And the Spirit of God moved upon the face of the waters.

3. And God said, Let there be light: and there was light. 4And God saw the light, that [it was] good: and God divided the light from the darkness. 5And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

Incorrect.


This animal does not see in 3-D:

Nor does this animal:

This one can, however:


In order to see in 3-D, eyes need to be positioned forward so that together they can take in nearly 180 degrees:

Cite a peer reviewed reference.

You seem to forget these animals you use as examples can move their head.
