Embryos are alive and wiggling!

Things got a little slow during lab today, so I put some eggs on a slide and took some pictures and video.  Looking at a still photo, they look fine.  It looks like it has its father’s eyes.  Not sure what all the other parts are.

But that doesn’t tell us whether they are still alive, does it?  Well, here is a little video.  Not all of them were moving, and it is still not clear whether they are hatching or getting eaten, but at least some are wiggling energetically.  After their brief moment of fame, all went back into the Box of Slugs.

    Bravo, an invertebrate physiologist’s sonogram: that is a great video. Is it a boy or a girl, or both? Leeuwenhoek would be very proud!

      Thanks! Too bad van Leeuwenhoek didn’t have a nice digital camera on his microscope.
