Story summary

A groundbreaking study by marine biologist Javier Montenegro uncovers a hidden barrier in the Arctic Ocean that shapes jellyfish distribution. The knobbed and knob-less jellyfish, sharing a genetic bond, are divided at 47 degrees north. This intriguing finding suggests that environmental factors may confine the knob-less jellyfish to Arctic waters, revealing critical gaps in our knowledge of deep-sea biodiversity.
