Dire wolves were exceptionally large compared to modern wolves, weighing in at around pounds. Extinction of their main prey at the end of the ice age led to increased competition for food between large predators, which contributed to the extinction of the dire wolf.
Many sets of dire wolf remains have been found in the La Brea tar pits in Los Angeles, which has allowed us to learn more about this unique species of wolf. Image Credit: " Dire wolf skeleton " by Ian E. They were common prior to , but were hunted and trapped to extinction within a year period beginning during the Alaska Gold Rush. The Newfoundland Wolf was a medium-sized subspecies of gray wolf native to Newfoundland.
The last known individual was killed in , and was officially recognized as a subspecies in This subspecies of gray wolf was found only on the Italian island of Sicily.
They went extinct in the early s due to human trapping, poisoning, and hunting, but there have been unconfirmed sightings up until the s. Image Credit: " Figure 5 " by Lorenzo Rossi. The Cascade Mountain Wolf, also known as the brown wolf, was a subspecies of gray wolf that lived throughout British Columbia, Washington, and Oregon.
It was originally thought to be a separate species, but was reclassified as a subspecies in , 65 years after its official extinction in Also known as simply the Florida wolf or black wolf, the Florida black wolf was a subspecies of gray wolf that, as the name would suggest, had predominantly darker fur.
It went extinct in due to habitat loss and hunting by humans. They went extinct due to hunting by humans to protect livestock during the Meiji Restoration period of the late s. Habitat loss from deforestation as well as hunting by humans led to their extinction by First noted in , the Texas wolf was a subspecies of gray wolf that featured slightly darker, reddish-brown fur than other wolf subspecies in its range of New Mexico and Texas.

A pack usually consists of a breeding pair, their current offspring, and a few yearlings. Wolves will usually stay with the pack until they are years of age. At that time, they may choose to disperse to join a different pack or to start a new pack of their own. Pack sizes depend on the available prey and territory. Wolf packs in Alaska and Canada are usually larger than in the lower 48 states, which is mostly due to the abundance of prey and larger available range.
Wolves have 42 teeth. There are 20 teeth in the upper jaw six incisors, two canines, eight premolars, and four molars , and 22 teeth in the lower jaw six incisors, two canines, eight premolars, and six molars.

Wolves trot at 5 miles per hour, but they can run in short bursts at up to 35 miles per hour. They can travel as much as 30 miles per day while hunting for food. Wolves and coyotes can look similar, but they are different animals and fill their own unique niches within an ecosystem. Can you spot any similarities? Wolves are found in the Northern Hemisphere and typically prefer high elevation forests and plains, though they can be found in most types of habitats.
Wolves can inhabit areas with enough prey deer, elk, bison, moose and a low population density of humans. In , a wolf tagged as OR-7 traveled over 1, miles and made his way into California from Oregon as a lone wolf looking for a mate. When he stepped foot into California, he was the first wolf in the wild in our state since He and his mate had five litters between and Journey and his mate paved the way for a population of wild wolves in California. As of , there is one known pack of wolves in Northern California, called the Lassen pack after the area that they inhabit.
The identity of the female is unknown. This pack has had three litters of pups so far, in , , and Currently, the pack is estimated to have a minimum of 14 wolves. Though wolves are endangered throughout the majority of the country, their populations and their conservation status vary by state.
