Bubblegum Coral: Deepwater Exploration of the Marianas 2016

Bubblegum coral with unidentified green filament, seen during a dive on June 17, 2016, in the Marianas region. The science team wondered if the green filaments were sponges or possibly algae snagged on the coral as they drifted down; generally, plants are not found at these depths due to the lack of light.
