Based on info I got by searching this sub, color vision exists to help forage for ripe fruit, while less cones/more rods help hunt/track movement etc – so it seems counter-intuitive for these predators to have such vast color vision.
Thank you

They don’t necessarily see *more* colors, but the additional cone cells in a mantis shrimp help them *differentiate* colors better. When your prey is well camouflaged this can be important. It’s hard for our human eyes to tell grasshopper green from grass green, but some of their primary predators are much better at this.
Some birds also use seem to cones that extend into the near UV that we can’t see to track insects. Insect exoskeletons are more reflective in the UV spectrum.
