Jim writes, "This radiolarian (of the Polycyttaria) represents for me the staggering complexity, beauty and wonder of life. That such an amazing looking critter can evolve, and be so amazingly intricate and small blows my mind. I love talking science, and so far (have had it for less than 24 hours) heaps of people have asked, 'That is great; what is it?' And after the brief explanation, they are always amazed."
Here are drawings of Polycyttaria by Haeckel. And here is an entire web site dedicated to radiolarians.
