Wolverines are the largest member of the weasel family, so, like skunks and minks, they have scent glands but do not spray like a skunk. They are always on the go, traveling many miles a day. And they are extremely aggressive, at least to other animals. They have been documented as chasing a grizzly from the bear's own kill! They are a trapper's worst nightmare. When a wolverine locates a trapper's trapline, it will steal the trapper's catch at every set, every night, on the entire line, causing the trapper to locate a new area in which to trap. They are very intelligent and are very difficult to hold in a leg-hold trap. They can chew through large bones like they were toothpicks. They are my favorite of all mammals.
