A harpoon (from French harpon) is a long spear-like instrument used in fishing to catch fish or other large aquatic animals such as whales. A harpoon can also be used as a weapon.

[edit] History of the harpoon

The Greek historian Polybius (ca 203 BC-120 BC), in his Histories, describes hunting for swordfish by using a harpoon with a barbed and detachable head. [1]

[edit] Whaling

For over 1000 years, the two flue harpoon was the primary weapon used in whaling around the world, though in the Arctic, natives used the more advanced toggling harpoon design. In the early 19th century the one flue harpoon was introduced, which reduced failed harpoonings due to the head cutting its way out of the body of the whale. In the mid-19th century, the toggling harpoon was adapted by Lewis Temple, using iron. The Temple toggle was widely used, and quickly came to dominate whaling.

In the 1860s, Svend Foyn successfully patented and pioneered the exploding harpoon and gun based on Erik Eriksen (explorer)'s idea and design. Together with the steam-powered chaser boat, this development ushered in the modern age of commercial whaling. Whalers were now equipped to hunt faster and more powerful species, especially the rorquals, which were invulnerable to the handheld harpoons.

A modern harpoon usually consists of a deck-mounted launcher (mostly a cannon) and a projectile which is a large spear connected to a thick rope. The spearhead is shaped in a manner that it will penetrate the thick layers of whale fat and stick in the flesh. It has sharp spikes to prevent the spear from sliding out. Thus, by pulling the rope with a motor, the whalers can drag the whale back to their ship.

A recent development in harpoon technology is the hand-held harpoon gun. Divers use the harpoon gun for defense against dangerous animals. They are also used for poaching of marine animals like sharks and dolphins. The harpoon gun has been made famous in the entertainment industry by characters like James Bond and in a recent television commercial for life insurance. Harpoon guns may be powered by pressurized gas or with mechanical means like springs or elastic. Diver characters in Lego toys may possess miniature models of harpoon guns.
