Beyond awesome. What's the time span on this? 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.
