My scientific specialty is chronobiology (circadian rhythms and photoperiodism), with additional interests in comparative physiology, animal behavior and evolution. I am not an MD so I cannot diagnose and treat your sleep problems. As well as writing this blog, I am also the Online Discussion Expert for PLoS. This is a personal blog and opinions within it in no way reflect the policies of PLoS. You can contact me at: Coturnix@gmail.com

This series of videos on the development, one each morning this week, were discovered by my BIO101 students.

Wooooooaaaaaahhhhhhh. Beyond awesome. What's the time span on this?
Posted by: Mad Hussein LOLscientist, FCD | October 22, 2008 2:57 PM
Very nice!
The time post-fertilization at "room temperature":
2-cell: 90 minutes
32-cell: 3 hours
blastula: 4-7 hours
gastrulation begins: 9 hours (hard to see in the video)
the final stage shown looks like about 1.5 day-old tailbud.
See drawings of the stages. And a bunch more movies of Xenopus development.

Awesome Video! Does anyone know the life expectancy of a xenopus? Mine is at least 23 years old.
