Living Brine Shrimp Weirdness?

[esn]

I purchased a bunch of live brine shrimp two days ago to feed a finicky juvenile axie, and they're just sitting in a a little ziploc tupperware of brine, the water that I got them in. I noticed something weird going on, though. In the tub there are white fluffy sorts of things all over, and a large orange mass at the bottom, all close together. In the tub that my axie is in, the brine shrimp are all surrounding little white fluff balls. I have no aeration. Any idea what this all is?

Could they be dead shrimp? When I kept sea monkeys they went somewhat fluffy for a short while after they died, then shrivelled and went black

It's not dead shrimp. They're seriously little white fluff balls that groups of brine shrimp are carrying around.
