The Deepest Part of the Ocean!

The Mariana Trench, located in the Pacific Ocean near China, is the deepest part of the ocean, reaching almost 11,000 meters. Despite its extreme conditions of darkness, cold, and pressure, unique life forms like sea cucumbers, amphipods, and foraminifera thrive there. These organisms have adapted to survive without bones due to the intense pressure. Human exploration of the trench is limited due to the challenges and costs of building suitable submarines and robots, leaving much of the trench a mystery.
