Underwater hunting, also known as spearfishing, involves catching fish and other marine life while submerged in water. This activity can be done using various tools, such as a speargun or a pole spear, and often requires the hunter to hold their breath or use scuba gear for extended dives. Participants typically hunt in oceans, lakes, or rivers, targeting species like snapper, tuna, or lobster. Underwater hunting is regulated in many areas to ensure sustainable practices, and hunters must often adhere to local laws regarding seasons, size limits, and protected species.
