|I check the pond at 7:45 in the morning and find this. The eggs are only at the 4-cell stage labelled Stage 4 (modified Gosner stage from Anstis 2002). That means there have only been two cell divisions. Now that is cool.|
An hour later, 8:35, and another cell division has occurred. The eggs are now at stage 5 and consist of eight cells. You can clearly see the division between the animal (top) and vegetal (bottom) poles.
It's 9:20 now, and stage 6 (16 cell)
10:30 and the cells are getting smaller and smaller (stage 7-8ish)
The cells are scarcely distinguishable from each other at midday
The surface is now almost entirely smooth at 4:45 in the afternoon, after stage 9. Next stop, gastrulation! But I don't have photos of it. So there's a big gap between now and the next photo.
