Fish hook

Summary
A fish hook or fishhook, formerly also called angle (from Old English angol and Proto-Germanic *angulaz), is a hook used to catch fish either by piercing and embedding onto the inside of the fish mouth (angling) or, more rarely, by impaling and snagging the external fish body. Fish hooks are normally attached to a line, which tethers the target fish to the angler for retrieval, and are typically dressed with some form of bait or lure that entices the fish to swallow the hook out of its own natural instinct to forage or hunt. Fish hooks have been employed for millennia by fishermen to catch freshwater and saltwater fish. There is an enormous variety of fish hooks in the world of fishing. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the hook. Fish hooks are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of artificial, processed, dead or live baits (bait fishing); to act as the foundation for artificial representations of invertebrate prey (e.g. fly fishing); or to be attached to or integrated into other devices that mimic prey (lure fishing). In 2005, the fish hook was chosen by Forbes as one of the Top 20 tools in human history. The fish hook or similar angling device has been made by humans for many thousands of years. The earliest prehistoric tackle is known as a gorge, which consisted of a double-pointed stick with a thin rope tied to the middle. When angling, the gorge is laid parallel to the line and buried inside a bait ball, which can be swallowed easily by the fish. Once inside the fish's mouth, the bait ball often softens and gets fragmented by the pharyngeal teeth, and any pulling along the line with cause the freed-up gorge to rotate transversely and get stuck across the fish's gullet, similar to how a fish bone or chicken bone may pierce and obstruct a man's esophagus. They performed similar anchoring functions to hooks, but needed both ends to claw firmly into the fish's gullet to work properly.
