What is a diving under water with a breathing tube?

Diving underwater with a breathing tube, commonly known as snorkeling, involves using a snorkel, which is a tube that allows the diver to breathe while their face is submerged in water. Snorkelers typically wear a mask to see underwater and fins to aid in swimming. This activity enables individuals to observe marine life and underwater ecosystems without the need for more complex diving equipment. It is often done in shallow waters, making it accessible to people of various skill levels.
