What Color Is a Tadpole Egg

The embryos start out black on top and white on the bottom, as do most open-water amphibian eggs, but as the embryo develops into a tadpole the white is lost.

Why are tadpole eggs white?

These experiments give us a suggestion for why the initially white toad eggs developed into normal black tadpoles. If their mother had two copies of the recessive albino allele, she would not have been able to produce the black pigment found in normal eggs. As a consequence, the eggs she produced would be all white.

What is the Colour and size of frog egg?

Wood frogs lay eggs (see picture above) in a large globular mass about 2 to 5 inches in diameter (roughly the size of a softball). There are about 500 to 2000 eggs per mass, with embryos colored black on top and white on bottom. However, the white disappears as the larvae develops.
