Future Porcupine

The Future Porcupine (Hystrix futurum) is a porcupine that lives, on average, 4.692 seconds ahead of everyone else. It is unknown how this works. While some theorize that it moves more quickly than our senses, so we experience it 4.692 seconds behind what is really happening, it is generally believed that they are simply in the future, and that is just what happens.

Physiology
Future Porcupines only have six quills at any given time, which radiate from the body with an even distribution. It is thought that future porcupines do not actually need more quills, as they have ample time to arrange themselves optimally in order to meet oncoming predators.

Wiarton Willie Replacement
Due to the Future Porcupine's perceived prophetic abilities, it was hoped that one such specimen might be used to replace Wiarton Willie after his death in 1999 and thereby provide more accurate predictions about the number of weeks remaining in winter. This ultimately failed on account of several reasons:
 * There are no future porcupines whose names start with "W," making alliteration impossible
 * Future Porcupines are congenitally blind to their own shadows
 * Future Porcupines, unlike groundhogs, do not possess language
