Fairy Shrimp

I think they won't make it much longer in the wiggly state.

I did a little bit of research on the Internet, and found that indeed these creatures are Fairy Shrimp. They live in vernal pools, these are pools that dry up periodically. Well our Lake here doesn't dry up, but does freeze up totally. And that prevents fish from living in it. Which in order makes it suitable for Fairy Shrimp. Last week (see post:Giant Water Bug) they where still copulating, some of them clasped together; laying eggs for the winter in the mud.
This time, which the picture doesn't show, only some where still alive and wiggling,
They seemed to be hanging around the hole, which was totally frozen over today, but still had some light coming in.
