Mustela putorius furo

The ancestors of today's domestic ferrets ranged across Europe, Asia and North Africa, living in forests and thickets. They were domesticated as early as 2,400 years ago to hunt rabbits and eliminate farm and house pests. Ferrets are obligate carnivores, meaning they must eat meat in order to survive.

A ferret's long, tubular body and flexible spine allow it to turn its body 180 degrees (a letter U shape). "To ferret out" something means to search intensely for it, like this animal does when hunting prey.
