@mbari_news: Giants lurk in the ocean’s mysterious midwaters. While surveying the Gumdrop Seamount off the central California coast in 1998, MBARI staff spotted an unusual—and exceptionally large—jelly. This crimson creature was a full meter across. Unlike jellies that dwell near the ocean’s surface, this one didn’t have tentacles. Instead, a cluster of finger-like oral arms dangled beneath its bulky bell. A closer look confirmed this was a new species—and one that had actually eluded our scientists five years earlier. Detailed video observations captured by our robotic submersibles helped MBARI researcher George Matsumoto and his colleagues in California and Japan formally describe this unusual jelly. They named it Tiburonia granrojo in honor of MBARI’s now-retired remotely operated vehicle (ROV) Tiburon, which was instrumental in documenting this delicate drifter in its natural environment. #DeepSea #DeepOcean #BigRedJelly
