Science picture of the month: Hydra hatchling
I've talked her before about hydra and their reproduction, so I thought I should post a few out of the thousands of pictures I have of them. I particularly like this one, and have a copy o up on the wall in the lab. It is a hydra hatchling, right out of the shell. The three bumps at the lower end of the picture are it's stubby little baby tentacles. The diameter of that shell is a bit under half a millimeter.
