A snorkel is a breathing device used for underwater exploration. It typically consists of a long tube that allows a person to breathe while their face is submerged in water. The snorkel is often used in conjunction with a mask to provide a clear view of the underwater environment. Snorkeling is a popular recreational activity that enables individuals to observe marine life in shallow waters without the need for heavy diving equipment. It is commonly practiced in coral reefs, lakes, and coastal areas, making it accessible to people of all ages and skill levels.
