Fire everywhere.

It's quite possible that the spider is real. There's no sense of scale, but huntsman spiders of several inches width are quite common, and they typically lay one or two hundred eggs at a time. I don't think the babies hang around the nest all that long though, so the photographer must have been waiting for them to emerge.

I don't think that situation is typical however. I believe most of the larger huntsman species prefer to live outdoors, where insect food is more plentiful and hiding places are easier to find.

Still. Heebie jeebie.
