so how can this animal with such a minut

so how can this animal with such a minut brain have stereo vision and how would

brain have stereo vision and how would

brain have stereo vision and how would you even test this Vivek decided that

you even test this Vivek decided that

you even test this Vivek decided that the best way was to take the insect to a

the best way was to take the insect to a

the best way was to take the insect to a 3d action movie really in order to see

3d action movie really in order to see

3d action movie really in order to see the movie Vivek needs to make some very

the movie Vivek needs to make some very

the movie Vivek needs to make some very very tiny 3d glasses for the praying

very tiny 3d glasses for the praying

very tiny 3d glasses for the praying mantis we came up with the idea of 3d

mantis we came up with the idea of 3d

mantis we came up with the idea of 3d glasses with these two different glasses

glasses with these two different glasses

glasses with these two different glasses on each eye each eye could be shown a

on each eye each eye could be shown a

on each eye each eye could be shown a different stimulus so after various

different stimulus so after various

different stimulus so after various attempts at getting this done the one

attempts at getting this done the one

attempts at getting this done the one approach that seemed to work was to use

approach that seemed to work was to use

approach that seemed to work was to use colored filters it’s a quick procedure

colored filters it’s a quick procedure

colored filters it’s a quick procedure using beeswax to attach the 3d glasses

using beeswax to attach the 3d glasses

using beeswax to attach the 3d glasses and also a device that holds the Mantis

and also a device that holds the Mantis

and also a device that holds the Mantis in the stand for the experiment so I

in the stand for the experiment so I

in the stand for the experiment so I think we’ve got the green filter on the

think we’ve got the green filter on the

think we’ve got the green filter on the left eye and the blue filter on the

left eye and the blue filter on the

left eye and the blue filter on the right eye so I’m just gonna put it on

right eye so I’m just gonna put it on

right eye so I’m just gonna put it on the stand how can they make sure the

the stand how can they make sure the

the stand how can they make sure the Mantis is really seen 3d preying

Mantis is really seen 3d preying

Mantis is really seen 3d preying mantises will only strike at prey if

mantises will only strike at prey if

mantises will only strike at prey if they are close enough to their target

they are close enough to their target

they are close enough to their target Ginny and Vivek makes sure that the

Ginny and Vivek makes sure that the

Ginny and Vivek makes sure that the computer screen is out of the mantises

computer screen is out of the mantises

computer screen is out of the mantises strike range but the 3d target is within

strike range but the 3d target is within

strike range but the 3d target is within it and if the Mantis actually sees

it and if the Mantis actually sees

it and if the Mantis actually sees stereoscopically it will strike at the

stereoscopically it will strike at the

stereoscopically it will strike at the 3d target thinking it is close enough to

3d target thinking it is close enough to

3d target thinking it is close enough to go in for the kill

go in for the kill

go in for the kill okay here we go yeah and that’s good

wait for it wait for it and strike the

wait for it wait for it and strike the obvious reason why praying mantis would

obvious reason why praying mantis would

obvious reason why praying mantis would have evolved 3d vision is for predation

have evolved 3d vision is for predation

have evolved 3d vision is for predation if a prey comes within range they’ll

if a prey comes within range they’ll

if a prey comes within range they’ll reach out and grab it very quickly with

reach out and grab it very quickly with

reach out and grab it very quickly with a strike the strikes very all-or-nothing

a strike the strikes very all-or-nothing

a strike the strikes very all-or-nothing you have to get it right there isn’t

you have to get it right there isn’t

you have to get it right there isn’t going to be a second chance so it’s very

going to be a second chance so it’s very

going to be a second chance so it’s very important for the Mantis to know exactly

important for the Mantis to know exactly

important for the Mantis to know exactly how far away the prey item is before it

how far away the prey item is before it

how far away the prey item is before it releases its strike yes we got a strike

releases its strike yes we got a strike

releases its strike yes we got a strike yeah okay yeah it definitely works and

yeah okay yeah it definitely works and

yeah okay yeah it definitely works and yeah brilliant

yeah brilliant

yeah brilliant Ginni and vivek still have a lot more

Ginni and vivek still have a lot more

Ginni and vivek still have a lot more experimentation to do to figure out the

experimentation to do to figure out the

experimentation to do to figure out the algorithm that defines a praying

algorithm that defines a praying

algorithm that defines a praying mantises stereo vision and it could be

mantises stereo vision and it could be

mantises stereo vision and it could be that it’s a different type of stereo

that it’s a different type of stereo

that it’s a different type of stereo vision than ours

vision than ours

vision than ours what possibility that I see is that

what possibility that I see is that

what possibility that I see is that mantises have kind of evolved a quick

mantises have kind of evolved a quick

mantises have kind of evolved a quick and dirty stereo vision maybe it’s not

and dirty stereo vision maybe it’s not

and dirty stereo vision maybe it’s not as good as ours it doesn’t work in as

as good as ours it doesn’t work in as

as good as ours it doesn’t work in as wide a variety of images it does the job

wide a variety of images it does the job

wide a variety of images it does the job for them and I think that will be really

for them and I think that will be really

for them and I think that will be really interesting not just from an

interesting not just from an

interesting not just from an evolutionary point of view but perhaps

evolutionary point of view but perhaps

evolutionary point of view but perhaps it’s something we could use
