welcome to my science project for S CHOOL i made the intro look like a dvd menu >:3 click "PLAY VIDEO" to play.. the video script: Mantis Shrimp: We have three cones in our retinas that send green, red, and blue signals to our brains, which then converts them to a hue. Mantis shrimp work differently. They have 12 receptors cramped into the horizontal line on their eyes. in order for them to see a color, they have to essentially scan their environment like a scanner at a grocery store reading a bar code by swiveling their eyes! so, if you ever see them swiveling their eyes, that's them scanning their environment to see! Dragonfly: Dragonflies have eyes with 30 THOUSAND lenses that takes up pretty much their whole head, and all those lenses in their eyes make it really easy for them to see almost 360 degrees around themselves except for a blind spot directly behind them. This also allows them to change direction and speed like, really fast. Deer: Deer are colorblind to most warm colors like red and orange but they can see shades of blue and green very well, especially at night when they are most active. They can also detect movement essentially "out of the corner of their eyes" because their spectrum of sight is higher than ours at 300-310 degrees. So that's why a deer will run away from you the second they see you! Bonus info! The underside of most deers' tails are in the blue spectrum that deer see in and so when they stick their tails straight up, they're essentially waving a bright blue flag for other deer to see that says "DANGER!" which i thought was pretty cool!
