It's my favorite lab to teach, development! Here is a video of the first division of a fertilized sand dollar embryo. It's a little choppy, I was trying to figure out how to speed it up in the new iMovie program and was only partially successful.
I am a student of Marine Biology, just finished up my masters and no longer contemplating continuing on... I AM continuing on! Most of my clothes are salt stained and my personal philosophy is ‘Spineless is splendid’.
