Organisms adapt by changing their physical characteristics and behaviors to live in extreme environments. For example, deep-sea creatures have evolved to withstand high pressure and lack of sunlight, while high-altitude animals have adapted to low oxygen levels. These adaptations help them survive and thrive in their harsh surroundings. Some specific examples of deep-sea creatures are tubeworms and giant tube worms that live near hydrothermal vents, while examples of high-altitude animals include snow leopards and Tibetan antelopes that are adapted to survive in mountainous regions with thin air.
