@MissLilPopstar its genetically modified with a protein from jellyfish called GFP. It's an indicator gene, basically you insert it into a part of the genome to see what parts of the body that section is expressed, here it's expressed in the blood vessels (so it might have inserted next to a gene important in blood). So its usually being used as a tool to study organisms. There are some other uses of GFP in cell biology (as opposed to this which is more physiology).
They are good for genetic analysis (birth defect kind of stuff), are transparent, so you can see the kind of stuff in the movie without dissecting or killing the embryo, and they can be manipulated to add genes or cells, or take them away.
a genetically modified fish?does it go through mutation?or is it a cross bred fish?

That's very very impressive. How small is it? what magnifications did you use?

@ParaglidingManiac
Can't recall the magnification. No more than 200x. The heart is probably around 100µm across (0.1mm). Glad you liked it.

@kjpg2005,\
Another question. How did you mount your camera to capture this footage, please?
ParaglidingManiac 1 year ago
@ParaglidingManiac
the movie is taken on a compound,upright microscope and the camera is attached to the microscope head through a dedicated attachment.

This might be a dumb question, but why are zebrafish tested on the most?

I think you missed the point that they are probably the easiest oviparous fish to reproduce in captivity :P

THIS IS AMAZING! I'm thinking about doing research in a lab that works with zebrafish embryos. I have never seen this fish before so yeah nice vid.
