Laying females will dig a brooding chamber, lay the eggs and then wrap themselves around their brood. They will wait until they hatch (as these have), then continue to guard them for their early life. The mother will spend months curled up like this and won't eat for all that time. These young centipedes are near the very end of that period and will soon be fully independent.
I love spiders and pretty much all crawling things. But centipedes evoke sheer horror in my lizard brain.
One time I was in Thailand, and this enormous centipede came ambling down the street. I was taking a picture and this Thai dude zoomed up on a moped, hopped off, grabbed a broomstick and killed it. He then scolded me because apparently it was very dangerous.
Yeah they're venomous.
