Via skeptv, New Scientist reports on this time lapse video of snail development from embryo to hatching:
Oliver Tills of Plymouth University, UK, and colleagues tracked the timing of 12 different events – including the formation of the eyes and the shell – over the two weeks it takes embryos of the pond snail Radix balthica to develop. They then compared these figures with those obtained from the snail’s parent (R. balthica is hermaphroditic so can have just a single parent).
There are more videos with cells in the archives.
