Unidentified Ghostly Deep-Sea Creature Baffles Researchers Off Japan

Researchers filming with HD cameras on the Limiting Factor off Japan captured footage of a pale, ghostly deep-sea organism at about 29,960 feet, in the Ryukyu Trench. Despite consultations, scientists could not classify the creature, labeling it Animalia incerta sedis and noting mollusk-like, nudibranch-adjacent features that don’t fit known species; its exact identity remains unknown despite examining 108 other organism groups during the expedition.
