  • How did you stabilise it? they move really fast!..

  • @kevmem2000 We stabilised it by using a cavity slide with only a very small amount of water, and then carefully using a cover slip to hold the daphnia in place. It took a few attempts, and I think the Daphnia in the video was on its last legs which is why it was a lot calmer than normal.

  • That's not the heart beat!

    What looks like its heart beating, is in fact its appendages creating a water current for feeding purposes!

    The heart is located above, on its back.

  • @The88Nomad You do realise that the heart is visible in the video...beating...
