This unidentified purple orb stumped scientists onboard. After sampling, it began to unfold to reveal two distinct lobes.
It could possibly take years for scientists to definitively determine whether it's a newly discovered species!
EVNautilus: We're still working on a species ID with our science partners at the Harvard Museum of Comparative Zoology, but currently we're thinking the purple orb is a pleurobranch, a nudibranch relative. Both are types of sea slugs.
