WOLVERINE
(Gulo luscus)
Description: Wolverine looks like a cross between a weasel and a bear. They are about the size of a medium sized dog, but don’t let that fool you. Wolverines are powerful and very territorial. Not a good animal to mess with!
Habitat: Wolverines are found in the tundra, forests and mountains. They like wilderness areas, far away from people.
Diet: Wolverines primarily eat carrion. That means they eat animals that are already dead. In the winter they will hunt and kill deer, mountain goats and other large mammals.
Reproduction: Wolverines give birth only once every two years. Between May and August. The embryo is not implanted immediately, but rather waits in dormant stage for six months. After implantation, gestation takes only another 30-50 days. Dams build snow-dens in which they give birth and nurse. Births occur from January through April. Litters are from one to six. These young typically nurse for 8-10 weeks, are separated from the mother in the fall, and attain adult size after 1 year. Wolverines are sexually mature at 2-3 years of life. Females up to 10 years old have bred in captivity. Wolverines may live up to 17 years in captivity, but they generally succumb after 8-10 years in the wild.
Trivia:
Although they are small, no animal will fight with a wolverine. They will chase wolves away from their kills, and even huge grizzly bears will get out of their way. |
