Eggs & Tadpoles

Eventually I'd like to take a series of pictures documenting the development of frog eggs for my project data. Here are a few shots:

Eggs (Day 2) The black spheres are the actual living tissue, contained within yellowish jelly. They are the size of BBs.

Eggs (Day 6) This is a different clutch. Note that the head and tail ends can be distinguished, and the jelly has lost its yellowish tint.
