Horned spiky green and black thing in blackreach?

[MiriDew]

I was in blackreach just now and found a black with moss or something green.... thing. A hollow.. pod? I hit it and it broke open, and pieces flew everywhere. It was empty It is along the waters edge, a little bit underwater, and next to a bridge, ill include a locational reference photo of the bridge and background shrooms if anyone else wants a look see.

What in Bethesda's name is it? I cant find any reference to anything like it anywhere in the web and my boyfriend who is super mr skyrim has absolutely no idea.

*I have hearthfire and dawnguard installed, and it is on xbox 360. Please help, im so confused.

**Please excuse bad photos, my tv and camera dont work great together so everything turns neon blue.

That is not a glitch, it is part of the Dawnguard DLC. It is the cocoon of a chaurus turned into a chaurus hunter. It looks like it is open so it will not do anything until it re spawns. There are intact versions that will burst open releasing the chaurus hunters for you to fight if you are detected and get too close. for more information on chaurus / chaurus hunters check the below links.

If it's empty, doesn't grant you anything, and you can't find any reference to it on the web, then chances are it really isn't that important.

Maybe, it got there from a glitch.....
