Varieties of life under the sea
I am continually amazed at the wide variety of shapes of plant and animal life. Today, I ran across this series of photos of sea life, some of it from the deep sea. If I had been asked to design a new underwater life form, my imagination would not possibly have been able to concoct functioning animals like these. It's incredible that each of these life forms continues to live today, the successor to a long series of earlier and simpler life forms.
