Dinosaurs were not yet roaming the earth when an invertebrate known as the sea spider was beginning to evolve in the oceans 500 million years ago.
“They’re still evolving today and they’ve diversified in amazing ways,” said CSU Channel Islands (CSUCI) Associate Professor of Biology Geoff Dilly, Ph.D. “You can find them in tropic coral reefs or polar waters in the North or South Pole. They are found in every ocean in the deep sea. Some are three feet across and some are fingernail-sized off the Channel Islands.”
