Weird things growing in my sump

So I was looking in the sump with a flashlight this morning and noticed these weird whitish things all over. Some are pretty small, but some are about 1/2 long. They are kinda hanging from the sides and the bottom of the sump. I scooped out a couple to get a closer look and they are kinda firm sorta like pieces of shrimp and they have what sorta look like a mouth. They don't move or anything though??
I tried to get pictures, but they aren't very good.
Here is one of the larger ones...

And here is a group of small ones on the side of the sump...
