The largest venomous snake is the King Cobra, having reached lengths over 18 feet. Gaboon Vipers have the longest fangs of any snake, sometimes reaching nearly two inches in length. The Alligator Snapping Turtle opens its jaws and wiggles a special worm-like appendage in its mouth in order to attract fish. The longest-lived turtle is the giant tortoise of the Galapagos Islands, with one documented at an age of over 200 years. Reptile Gardens' oldest Galapagos Tortoise is well over 100 years old.
Snake venom is really just highly specialized saliva.
