A glass-bottom boat is a type of vessel designed with transparent panels in the bottom, allowing passengers to view underwater life without getting wet. These boats are commonly used in tourist areas, especially in locations with vibrant marine ecosystems, such as coral reefs. Passengers can observe various aquatic species, including fish, sea turtles, and plants, while enjoying a comfortable ride on the water. Glass-bottom boats are often operated by tour companies and provide an educational experience about marine biology and conservation, making them popular among families and nature enthusiasts.
