Is there a way to share it?

Oo, that made me nauseous. It looks so much like a crab. But yours spun web from its butt, mine has a pipe under its belly. Totally freaked me out, made me nauseous, I was mortified.

Hi, this is a Tropical Orb-weaver, Eriophora ravilla.

So these spiders have pipes underneath their bellies? The underbelly, I’ve never seen that before on a spider.

ItsyBitsy

Yes, that makes this a mature female. It’s called a “scape” and is a part of the epigynum (female reproductive organ) on some species of spiders. Edit: I thought I was still commenting on your own image. The scape is visible on this image: https://spiderid.com/picture/53459/

Now I’m not sure if you were commenting about the clear image of the scape on your own image or spinnerets, the part of the spider that produces silk which are also sometimes informally called “pipes”.

I don’t know the correct terms. I’m only calling it by what it looks like to me. And I read talking about on my spider picture.
