Here are some pseudo "ultrasound" baby videos (microscope videos) of Lucky developing. It seems he/she has hatched and is developing nicely (any guesses on gender?

).
You can see its heart beating and the blood circulating through the new arteries/veins. In the last video you can even see individual blood cells squeezing through a small blood vessel at the tip of the tail.
I'm trying my best to get a proper dedicated "photomicro adapter L" tube so I can mount my high definition camera to the microscope, but the part seems exceptionally rare now
Be sure to watch these on 1080p (HD) and full screen if you want to see the blood cells!At 100x (body shot)
