Submersibles are small underwater vehicles designed to explore the depths of the ocean. Unlike submarines, which can operate for long periods, submersibles are often used for specific missions, such as scientific research or underwater exploration. They can carry a small crew or be remotely operated, allowing scientists to study marine life and underwater landscapes. These vehicles are equipped with special technology, like cameras and sensors, to gather data about the ocean. Famous submersibles, such as the Bathyscaphe Trieste, have reached extreme depths, helping us learn more about the mysterious world beneath the waves.
