An underwater voyage has revealed a network of creatures thriving at the bottom of deep-sea ocean trenches. In these extreme environments, the crushing pressure,

Scientists have filmed odd communities of life flourishing deeper in the ocean than ever before. The chemosynthesis-based life-forms get their energy from chemical reactions, powered by gases seeping out of faults on the seafloor.
