Is the comb jelly still alive?
Despite going extinct over 400 million years ago, ancient comb jellies are still blowing scientists away. Long thought of as entirely soft-bodied creatures — like their modern counterparts — these predatory marine animals may have had hard, skeleton-like parts, according to a study published in Science Advances today.
