The excessive salt and no oxygen combo of a newly found lethal brine pool within the Pink Sea kills nearly any critter with the misfortune to swim into it. This salty spot 1.1 miles beneath the ocean’s floor is certainly one of Earths’ most excessive environments, in keeping with scientists who printed their paper final month within the journal Nature.

“Any animal that strays into the brine is instantly shocked or killed,” mentioned Sam Purkis, a College of Miami researcher, as reported by Dwell Science.
Purkis led a staff of scientists who discovered the pool utilizing a remote-operated underwater car in a 2020 exploration. Creatures within the know — savvy shrimp, fish and eels — float in wait exterior the pool, swallowing up the unfortunates that overdose on brine.
Brine swimming pools aren’t a brand new scientific discovery, however this one is surprisingly near the shore — simply 1.25 miles off Egypt’s coast. Earlier than this discovery, the closest identified Pink Sea brine pool was greater than 15 miles offshore.
Along with the Pink Sea, which incorporates about 25 identified brine swimming pools, the Mediterranean and the Gulf of Mexico are different worldwide brine pool sizzling spots. A YouTube video explains the formation of those odd undersea lifeless zones. The Gulf of Mexico was shallow throughout the Jurassic Interval. Closed off by land, the ocean evaporated, leaving a whole lot of salt. Layers of sediment protected it.
Later, when the gulf stuffed in once more, cracks within the sediment finally let some water seep in, mixing with the hidden salt. Then dense, salty water slipped out, pooling into basins and forming undersea lakes. This form of salt tectonics ends in stunning underwater ridges and valleys. And a lethal atmosphere for unsuspecting fish.
The newly found pool is within the Gulf of Aquaba on the Pink Sea’s northern tip. This was the primary pool within the space scientists have discovered exterior the Pink Sea correct. Scientists are excited as a result of they consider the pool’s hyper-salinity may provide clues to formative years on Earth — and even past it.
