Agkistrodon piscivorus is a venomous snake, a species of pit viper, found in the southeastern United States. Adults are large and capable of delivering a painful and potentially fatal bite. When antagonized, they will stand their ground by coiling their bodies and displaying their fangs. Although their aggression has been exaggerated, individuals may bite when feeling threatened or being handled. This is the world's only semiaquatic viper, usually found in or near water, particularly in slow-moving and shallow lakes, streams, and marshes. The snake is a strong swimmer and will even enter the sea. It has successfully colonized islands off both the Atlantic and Gulf coasts.
The generic name is derived from the Greek words ancistro (hooked) and odon (tooth), and the specific name comes from the Latinpiscis (fish) and voro (to eat); thus, the scientific name translates into “hooked-tooth fish-eater”. Common names include variants on water moccasin, swamp moccasin, black moccasin, cottonmouth, gapper, or simply viper. Many of the common names refer to the threat display, where this species will often stand its ground and gape at an intruder, exposing the white lining of its mouth. Three subspecies are currently recognized, including the nominate subspecies described here. Its diet consists mainly of fish and frogs but is otherwise highly varied and, uniquely, has even been reported to include carrion.

A mechanical traveller is a moving part of a machine, typically a ring that slides between different positions on a supporting rod when the machine goes through its operating cycle. The term may also be used refer to the supporting rod.
In sailing, it is a mechanical device used to modify the location at which lines used to control sails (such as sheets) are attached to the vessel. The attachment is often by means of a block through which the line runs; the block can move along the traveller. This allows independent control of the direction and tension of the line running through the block, which allows the sailor to position the block in the optimal location for the wind conditions and desired sail trim. This kind of traveller is often a metal track, which is attached to the deck of the boat. The block is attached to a "car", which much like a miniature railroad car, attaches to the track and slides along it in either direction. A traveller on a smaller craft (such as the popular single-handed "Laser" sailboat) might simply be a line attached to two points on the deck, along which another block runs. The term traveller can also be applied to the specialized lines used to control the location of the block.
