The Encyclopedia of Life brings us a new installment of the podcast, One Species at a Time. Vacuumed up from its habitat a mile down in the ocean, the red paper lantern jelly may not look like much. Mostly water, it’s so fragile that once brought to the surface it’s reduced to a tattered blob in a jar. But this unassuming jellyfish has lessons for scientists. It’s teaching researchers in Japan how intricately life is connected down in the ocean’s deep, dark depths—and how the fate of this small red lantern sheds light on the fragility of life close to home.
