Chewbacca Coral: The Shaggy Giant of the Deep Sea

Dive into the discovery of Iridogorgia chewbacca, a shimmering deep-sea bamboo coral whose thousands of active polyps cloak its stalk in a fuzzy, iridescent halo. We unpack what a monopodial spiral axis means, how this species survives at 400–1,000 meters in the western Pacific, and why archival ROV footage led scientists to formally describe it as a new species in 2025. Along the way we explore the ecology of deep-sea suspension feeders, the patience of taxonomy, and why a memorable name helps illuminate the science lurking in the ocean’s depths.
