Fisher is the common name for a largely arboreal, North American carnivorous mammal. Despite its name, this animal seldom eats fish. It is a weasel of the Mustelidae family.
With its speed and agility, the fisher is a remarkable predator that captures a wide diversity of prey: Rabbits, hares, squirrels, mice, grouse, and so forth. Even the well-protected porcupine is captured by the fisher, using a unique technique designed to tire the porcupine until the fisher can kill the large quilled rodent.
The Fisher is a top predator. For thousands of years the dense, lustrous coat of the fisher has been prized.
