Where can I learn more about this stuff? Also for other animals.
I remember reading that a fly's "framerate" is so high, it doesn't see an image on TV, just the dot created by the electron beam slowly making its way across.
- michaelmrose 4y ago> A new study shows that their rapid vision may be a result of their photoreceptors - specialised cells found in the retina - physically contracting in response to light. The mechanical force then generates electrical responses that are sent to the brain much faster than, for example, in our own eyes, where responses are generated using traditional chemical messengers. https://phys.org/news/2012-10-eye-mystery-insight-flies-fastest.html https://phys.org/news/2012-10-eye-mystery-insight-flies-fast...

- bitwize 4y agoMantis shrimp eyes, it turns out, aren't as extraordinary as you might think. Yes, they have twelve different color receptors... which means they can see twelve different colors. Near as I can tell they can't integrate all the input from their compound eyes into a single, cohesive image. Rather, different sections of their visual system are tied directly to ganglia that recognize features or movement characteristic of predators, prey, or other mantis shrimp.[0] It really is the simplest possible visual system that could work for a mantis shrimp. It's like the first engineer from Do-While Jones's story about the breakfast food cooker[1] designed the mantis shrimp's visual system, and the second engineer from that story designed ours. (Of course as far as Do-While Jones is concerned, both animals had the same designer.)
