• Jumping or falling deliberately, often acrobatically, into water. This, and also completely unequipped swimming underwater, is described on this page. See also Underwater swimming.
• Going underwater with or without breathing apparatus. When done for sport, this is sometimes called subaquatics. See:-
• * snorkelling and free diving: swimming underwater without breathing apparatus.
• * scuba diving and surface supplied diving: swimming or walking underwater with breathing apparatus.

Humans are not the only ones to dive (in sense 1). Some species of amphibious animals such as marine mammals and some seabirds dive to catch their prey underwater. When dealing with equipment such as submarines and underwater remotely operated vehicles, the act of descending into the water is called diving and the command for the descent, especially in battle, is "dive."

Scuba divers sometimes jump into water feet first from some height above the water (e.g. from a large boat or from a pier. Do not jump in head first if you are wearing any sort of scuba equipment or snorkelling equipment. In particular, an open-circuit scuba banging about on the back is big and hard and heavy and during a headfirst dive (in sense 1) may sprain or break the back or neck. Use one hand to hold your mask on.
