This Spitzer Space Telescope image of the Cassiopia Supernova Remnant shows you what it might look like to a Mantis Shrimp. They typically have at least eight distinct colour sensors in their eyes (up to sixteen!), some species see infra-red as well as ultra-violet, and some species have as many as three discrete ultra-violet “channels”. Except for an innate tendency to punch random things out, they’d make great scouts.
