An Entirely New Form of 3D Vision Was Just Discovered in Praying Mantises

Look at their tiny glasses!

Many vertebrate animals, including us humans, have two eyes that are able to perceive three-dimensional structures.

But a new study has discovered that praying mantises have an altogether unique ability to see in 3D.

This so-called 3D vision - also known as stereopsis - is how creatures with binocular vision produce depth perception when they're taking in the world.

Each of our two eyes sees the world from a slightly different perspective - these are then overlaid into one image in our brains, the slight differences between the two images allowing for an instantaneous calculation of distance (hence, depth perception).

1. Show it the 3-D version of this film!!!

DUN! DUN! DUNNNNN!!!!



on edit: I note that this film features William Hopper, private eye Paul Drake in the original Perry Mason, and Hedda Hopper's son. They dug deep in the casting office.

2. My kind of flick.

I'm going to look for it.

3. "the only insects that have stereopsis, they're actually the only invertebrates with this ability"

Wow, I had to think about that for a while. It seems really odd that cephalopods, with the most complex brains and nervous systems among vertebrates, don't have stereopsis. Apparently, though, they don't.
