Yeti Crab Discovery and Habitats

Scientists have discovered a new species of Yeti crab near Antarctica, living in deep-sea hydrothermal vents. These crabs have hairy undersides and live in darkness at depths over 7,800 feet. The male crabs are larger and stay near the vents to feed on bacteria, while females and juveniles move to cooler waters. Other species found include barnacles and a rare colorless octopus. The environment is harsh, with mineral-rich water reaching temperatures of 720°F, providing nourishment for bacteria. The discovery was made possible by advancements in technology, allowing exploration of previously inaccessible areas.
