Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts. "Adding some 200 million years to the age of jellyfish is quite a jump. While the fossil might not look like a jellyfish at first glance, it's important to note that, for part of their life cycle, neither do Medusozoans.
