    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.
