How sea anemones living on deep-sea hydrothermal vents avoid metal poisoning
Life near deep-sea hydrothermal vents can be pretty metal — literally.
In addition to crushing pressures, total darkness and scorching temperatures, poisonous plumes belch from beneath the Earth’s surface. Exhaust from these underwater chimneys contains particles of heavy metals like iron and manganese, which become toxic at high concentrations. But many animals cozy up next to these vents and form thriving communities, seemingly able to withstand the dangerous metals around them.
Now, researchers have a hint of how one creature
Under Hydrothermal Vents, Animal Life Is Discovered for First Time
Off the western shores of Central and South America, there is a Lovecraftian, lava-licked realm thousands of feet beneath the ocean. There, on the seafloor, volcanically powered exhaust ports known as hydrothermal vents fire off jets of water that reach temperatures of up to 700 degrees Fahrenheit. While the surfaces and peripheries of these vents have long been known to host a diverse mosaic of life, scientists had never known animals to find a home beneath these hellish geysers.
But
