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

   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.
