Bacteria Help Sea Blobs Morph Into Tubeworm Adults

Image
Marine tubeworms start their lives as floating blobs that drift through the ocean looking for a spot to take up residence as sedentary juveniles. Now, researchers have found the gelatinous larvae need a nudge from pointy bacterial structures to metamorphose.

In recent years, scientists have found that many seafloor creatures — including some species of coral, sea urchins and tubeworms — require bacteria to go through metamorphosis. But researchers haven't understood exactly what bacteria do to instigate this important transition.
