underwater caves

Underwater caves, also known as submerged caves, are natural underground systems filled with water. They often form in limestone or other soluble rocks through a process called erosion. These caves can be found beneath oceans, lakes, or groundwaters, and are often accessed through sinkholes or openings. They can host unique ecosystems, including specialized fish and plant life. Scuba divers often explore them for recreation or scientific research. However, they can be hazardous due to challenges like limited visibility, strong currents, and intricate passageways, making safety and proper training essential for exploration.
