Relaxing with jellyfish

I came across this relaxing video of comb jellyfish on Scientific American that I thought you would enjoy. I wonder if I could make this my screensaver…

    Agreed, that would make a great screen saver. You might want to take a look at the screen saver found at electricsheep.org, which produces forms similar to the jellyfish.

    This is very beautiful and intriguing.
    The comb jellyfish are the only animals that have nervous systems but lack neuron building genes. There has been much debate regarding the origin of these strange and interesting animals. In many studies of the comb jelly’s DNA, they have been placed “at the base of the tree of life” but sceptics wonder if genetic mutation has caused them to seem closer to the base of the evolutionary tree then they actually are. My question is, how can an organism be at the base of an evolutionary chain but be so vastly different from every other organism above it on that chain; how can comb jelly’s be so biologically separate and unique from those organisms said to have evolved from them.
