Life Under the Sea: Warm Volcanic Caves Reveal Hidden Ecosystems

Diving a mile and a half under the ocean's surface. You'll find a world as strange as any other planet—volcanic ridges and hot springs, known as hydrothermal vents, that spew warm chemicals. These vents attract all sorts of animals, like tube worms, that have special bacteria to help them survive. Scientists recently discovered something amazing: tiny tube worm larvae and giant snails living in volcanic caves beneath these warm vents. This finding shows that life can thrive in some pretty unexpected places. It's like finding a whole new world hidden under the seafloor!Scientists found these creatures during an expedition to the East Pacific Rise, a volcanically active ridge in the Pacific Ocean. They flipped over small parts of the seafloor with an underwater robot and uncovered the hidden habitat. This discovery suggests that life can connect between the seafloor and the subseafloor, making it possible for creatures to live above and below the ocean bed.
