The sea worms, which lived inside their host sponges, were discovered by researchers in Japan. Images of the worms were then sent to Professor M. Teresa Aguado at the University of Göttingen, who subsequently organised a field trip to further investigate the species.

A distinctive feature about the worm—the third species of branched sea worms ever discovered—is the fact that it has dozens of regenerative posterior ends that look like tree branches as they spread out from the main body.

On World Ocean Day, people everywhere can unite to celebrate and take action for our shared blue planet, with one ocean and one climate, which connect us all. Get together with your family, community, and /or your company, and join with millions of others around our blue planet to create a better future.



By working together, we can -- and will -- protect and restore our shared ocean and climate. Join this growing global celebration in June and continue to grow the engagement year-round!
