Here are three photos taken this afternoon, each at a slightly different stage to the others. I'm not 100% certain of the stages of the first and second photos but I'm sure of the third. They are presented here in order of developmental stage.

Early Gastrula:

Middle Gastrula:

Late Gastrula:

Really very impressive pictures!

Which lens do you use exactly?

These are wonderful pictures. I hope you keep us informed of the development process. I'm still surprised with the amount of invaluable information I get in this forum. Thanks!
 
An even later Gastrula (just prior to neurulation):

And now an Early Neurula:

Patrick: Glad you like them ;). The lens is the 60 mm f/2.8 D.

Filipe: I will keep up the development series ;). It's very good to hear that you enjoy are little community and you're very welcome to it ;).
 
Great pictures. Can you actually see all that detail with your naked eye? I love the detail, I think pictures like this could go into a biology text book in the sections were they talk about embryonic development.
 
Hi Ben. Well, thankfully my eye sight is excellent, so I can distinguish different stages of development very easily. I certainly can't see the individual cells past the first or second division. Neurulas are very easy to spot though. When spherical, this species' embryos are 2-2.5 mm across.

Embryology is a long studied subject and a standard for first year biology undergraduates (I was one). You can see better photos in textbooks ;). As far as I can remember, vertebrate development is nearly identical until tailbud development begins.
