from my observations i've noticed that when shrimp sleep they lay down with their head pointed upwards like this
@animeirl they're philosophizing when they sleep. wonder if they can dream
@shinkaiheigen probably. I read a scientific paper that presented evidence that ants dream so i would expect it extends to other arthropods.
@animeirl The better to watch for predators, I'd imagine.
@WatchingWolf i think its also just the way their body is shaped. if they're relaxed and not bending their body in some way then tilting their abdomen/tail down will til their head upwards
@animeirl Good point! Very likely that too.
@WatchingWolf sometimes they'll also rest (and possibly sleep) upside down hanging from the bottom of a leaf but this picture seems to be their most relaxed posture
@animeirl That sounds cute! And I imagine they can sleep while clinging to something, can stay safer that way.
@tija I can't tell from that view. I can identify done if them from their backs
