Purple Progenitors

"We inhabit the blue planet, but our knowledge of life underneath the blue surfaces of the ocean remains surprisingly limited. In reality, investigations of marine life have just begun, and it is only now, when we can utilize custom-built research ships and the finest modern technology, that we can learn how ecosystems in the oceans are structured and function."

"One of three new species of enteropneust acorn worm discovered during the mid-Atlantic survey, the creature has no eyes, no obvious sense organs, and no brain.
