‘Unlucky’ creatures that enter rare Red Sea brine pools are immediately stunned to death

Rare deep-sea brine pools discovered in the Red Sea may hold clues to environmental upheavals in the region that span millennia, and could even shed light on the origins of life on Earth, a new study finds.

Deep-sea brine pools are extraordinarily salty or “hypersaline” lakes that form on the seafloor. They are among the most extreme environments on Earth, yet despite their exotic chemistry and complete lack of oxygen, these rare pools teem with life and may offer insights on how life on Earth began — and how life could evolve and thrive on water-rich worlds other than our own.
