>>36196177No, but some (specifically those in the Salticidae family) can move their tube "eyes" inside their bodies to look around just like us.
https://www.youtube.com/watch?v=qCAKqXjQV1Q&t=43sThe dark part is the retina, when it moves around, it leaves a transparent space that can be easy to spot depending on the light. You pretty much can tell where it is looking in the video. If its eyes get completely dark.
Evolutionarily speaking, I consider these jumping spiders to have the most advanced eyes in nature by "fair size comparison" (this is: having in mind the resources and space available nature can work with on a family that can be as tiny as 1 millimeter):
>almost full 360 degree of motion vision (blind spot due to abdomen)>high resolution vision for the frontal eyes>tetrachromatic color vision (they see more colors than us)>range extends into ultraviolets>the 2 big eyes have telescopic vision>don't overlap, so no depth perception>nature still says it needs to calculate depth for distances>develop a method of where the cones are layered>only the green layer (deepest one) focus the image>calculate distances by comparing how fuzzy the other colors are compared to the green frequencyThey fucking separate the image in color frequencies to compare them based on the fact their cones are layered at different depths inside their eyes. Motherfuckers.
But wait there's more, those tiny 2 eyes at the sides of the big central pair?
>good detail and resolution vision as well>non-telescopic ample field so they do overlap>which means depth perception the usual way>if the 2 big eyes get damaged, they're still able to calculate distances and huntBasically, they have both separated telescopic and stereoscopic vision, and 2 different methods to calculate depth working at the same time.
>mfw I didn't want to sperg about spiders but cannot hide my autism in the endFuck, it's been so long since I saw relevant conversation about spiders.
