Is there anyone out there who can answer a couple of questions (one real-world, one speculative) for me about centipedes? I have googled the hell out of this but can find no clear answer.Boosts for visibility appreciated.#arthropods #myriapods #entomology #arachnids(I know they're not insects or arachnids but I'm reaching here)

@karawynn It might help to know the questions. I have a few people I might be able to ask.

@twizzt @nev The first question is whether centipedes a) can and b) do ever 'rear up' like a snake, either in a threat display or prior to striking something above ground level. (Illustrations of centipedes often show this pose, but I haven't found textual or photographic indication that it's a real thing. I've seen photos of *millipedes* rearing up like that, but idk if that's relevant or if centipede physiology doesn't allow for it.)

@karawynn @nev I'm not really the best person to answer, but yes, they can rear up at least a little. If you touch their back ends, they will occasionally rise up and curl backwards. So they can at least lift themselves a little. I have seen them walk a short way along the edge of something then rise up and pivot to start climbing. I doubt they would strike anything too far above them. I've only seen it as a defensive posture or locomotory function. I study wasps though...

@twizzt @nev I have another potential question that would build on the answer to the first one, depending.I also find myself wondering, in the species where the mother centipede constantly corrals the hatched young through their first one or two molts ... do the babies eat at all, in first and second instar stages? and if so, how and what?

@karawynn @nev On the fowl site, there is a user who posts videos of them eating. His username is something like @crevicedwelling and if you are willing to post there, he will tell you all you want to know

@twizzt oooh, excellent, thank you. I signed up for iNaturalist and then found out I can't message anyone until I make a certain number of site contributions (not easy!). But this guy is findable elsewhere.

@twizzt @karawynn yes, Derek Hennen is millipedes but he must know some centipede people

@twizzt @karawynn Anecdotally, I've seen the house centipede "rear up" but, like, horizontally, when on a flat surface at a right angle to the ground, to catch prey on a parallel surface. She kind of curls her front half around her prey. However, am not a centipedologist or whatever they're called.

@nev @karawynn they are so unexpectedly fast, its hard to process what you actually saw.
