    Hey, Roger. Any idea what these little critters are? There were a ton of them swimming in a small pool in granite at about 6,000 feet in the sierras.

    @jwg you nailed it. That's exactly what we determined that they are. Everything fits from life cycle, to feeding preferences, to seasons, etc.

    Thanks!

    good article indicating many species!
    I liked this tidbit, as I was thinking they must get spread around by birds to be in those rock pools; "Cysts are even resistant to stomach acids, such as those of migratory birds which might ingest the cysts while feeding in vernal pools."
    Curious about your Sierra location. Western, eastern, north, south?

    I'm not sure. A climber buddy posted the photos on FB. I'll ask him.
