Advertisement I've watched quite a few feeding, rehousing and yes handling videos. Aside from being escape artists, there's no sign or proof of intelligence. The gangilia are exactly the same with one exception. Centipedes are longer and have more of them. That just probably means you need to process more data to run 32 legs then 8 legs. Mantis shrimp and jumping spiders are both very visual predators that need to judge speed and distance quickly. I'm sure it probably takes more data processing to do that just from the physics involved. Can a centipede purposefully push a button, perhaps treated with a specific scent, to get a reward through conditioning? Can a spider do so? I haven't seen it done by anyone else.
