Actually they're naturally aggressive, even when bred in captivity when it's never known natural surroundings they are still aggressive, it's in their nature, they're apex predators among the inverts in their environment.I don't know what it is but it's certainly got lovely markings. I'd be pretty aggressive to if I'd been plucked out of my natural surroundings and put in a tub !
Yup I posted a video interacting with one a few days ago, the link is here: http://arachnoboards.com/threads/alternans-and-polymorpha-strange-interactions-vid.281477/Anyone have one with markings that are almost identical?
[previously was a photo here]There should be a sticky with centipede anatomy for newbies like there is on the T forums, I still dont know what a ring furrow is
S. alternans has no ringfurrow as far as I can see, though there is a very slight crease behind the cephalic plate that looks a bit like a ringfurrow, but is in no way as prominent as heros, polymorpha, or gigantea.It does
Edit: until I find a decisive picture, I'm actually not so sure.. xD
This great (NOT MY PHOTO) picture of an S. heros is a good example; I circled and arrowed to the ringfurrow. It's the crease on the first segment behind the cephalic plate (headplate). Only New World Scolopendra species have it with the exception of S. alternans, S. longipes, and a few others that do not.
