What is the biggest wolf in world?

The biggest wolf in the world is the Alaskan wolf (Canis lupus lupus), which is also sometimes called the Arctic wolf.

Here's why:

* Size: Alaskan wolves are the largest subspecies of gray wolves, reaching up to 6 feet in length and weighing up to 170 pounds.

* Habitat: They live in the vast and challenging environment of the Arctic, which has likely contributed to their large size.

While there are other large wolf subspecies, such as the Eastern wolf (Canis lupus lycaon) and the Canadian timber wolf (Canis lupus occidentalis), Alaskan wolves consistently reign supreme in terms of size.
