Jumping spiders are the only spiders that have moving eyes. Perhaps other spider species also have dreams but we couldn't observe evidence of REM-like sleep because they can't move their eyes!
- oblak 4y agoDo we really need super sophisticated scans when we can just observer their movements during sleep? I am no spider expert, of course. And yet I would expect a dreaming earthly creature to some sort of convulsions.
- cryptonector 4y agoSure, we might see other movements, but REM-like eye movements are quite a bit more suggestive, or at least they seem that way to me.
