A huge fatal pool that instantly kills or stuns everything that enters it has been found by scientists.

A member of the University of Miami team who discovered the pool, Professor Sam Purkis, noted that because it lacks oxygen and contains lethal levels of salt, any animal that enters the brine “immediately stuns or kills.”

Researchers once discovered a crab that had been dead for eight years but still had all of its soft tissue in tact. These deep ocean death traps literally pickle animals alive. Additionally, brine pools may include toxic substances like hydrogen sulphide, making them considerably more hazardous than they already are due to the lack of oxygen and fatal salinity levels.

The idea of an undersea pool that has a 100% fatality rate may sound horrifying, but the predators that can ‘feed on the unlucky’ and maintain the food chain will benefit from the creepy-sounding pools.

Purkis said in an interview with Live Science that the discovery would also aid researchers in understanding how the planet’s oceans first came to be.

He said: “Our discovery of a rich community of microbes that survive in extreme environments can help trace the limits of life on Earth and can be applied to the search for life elsewhere in our solar system and beyond.
