Although brainless and eyeless, jellyfish can still respond to changes in their environment, despite being little more than bundles of nerves. And the horseshoe crab has survived nearly unchanged for 350 million years, thanks to a remarkable immune system. The crab’s blood cells release infection-fighting antibodies, which scientists have transformed into a life saving test for humans. Invertebrates: Jellyfish and Horseshoe Crabs will put a little backbone into your aquatic science curriculum.
