I want to see some cleavage!

Cell division, that is.

It's 4:00 p.m. rather than a.m. this time, but otherwise, the story is much the same as my last post. I'm here again, trying to get an little experiment to work with my tunicates. I got plenty of eggs and sperm from the adults, but for some reason, the fertilized eggs are just not dividing. I must have done something wrong, but cannot think of what it might be.

It is absolutely maddening, because the number of animals is running low now, so if I don't get the data today or tomorrow, I'm back to my waiting game. When will the next rack of animals come in so I can try to do this experiment again...?
