Art forms of nature

I've always loved biological/scientific illustrations. They can be so beautiful, whimsical, and sometimes a bit creepy. Some of the most classic examples were done by Ernst Haeckel (1834-1919), a German biologist, naturalist, philosopher, physician and artist.

His book, Art Forms of Nature, is full of incredibly detailed drawings.

I'm so amazed at how eerily beautiful nature can be. It's also incredible how scientists can be such talented artists. Who would have thought?
