[22] Sometimes there is debate whether the muskox or the Arctic hare is the primary prey for the hare-wolf-muskox predator-prey system.
The primary predators of muskoxen are arctic wolves, which may account for up to half of all mortality for the species. Other occasional predators, likely mainly predators of calves or infirm adults, can include grizzly bears and polar bears [7] and wolverines. [dubious – discuss] [citation needed]
The caribou rarely travel more than 150 km (93 mi) from their winter feeding grounds to the summer ones. They are able to outrun the Arctic wolf, their main predator, and are good swimmers. They usually travel in small groups of no more than twelve in the summer and four in the winter.

The endangered predators are regularly monitored as part of the Ethiopian Wolf Conservation Programme, founded by Sillero in 1995 following his first few visits to the region.
The wolf must give chase and gain on its fleeing prey, slow it down by biting through thick hair and hide, and then disable it enough to begin feeding. [4] After chasing and then confronting a large prey animal, the wolf makes use of its 6 cm (2 + 1 ⁄ 2 in) fangs and its powerful masseter muscles to deliver a bite force of 28 kg/cm 2 (400 lbf/in 2), which is capable of breaking open the ...
The Alaskan subspecies of moose (Alces alces gigas) is the largest in the world; adult males weigh 1,200 to 1,600 pounds (542–725 kg), and adult females weigh 800 to 1,300 pounds (364–591 kg) [17] Alaska's substantial moose population is controlled by predators such as bears and wolves, which prey mainly on vulnerable calves, as well as by ...
