Humans are the main predators of wolves. We have guns and traps. But wolf pups are very vulnerable to many things. The elements can freeze them, they can get left behind and starve, they might get killed by birds, bears, and other carnivores. Humans Predators, really none, a bear if the wolf comes to close to it Wolves do have enemies, but no predators that prey on them. Grizzly bears can very easily kill wolves, but they do not intentionally hunt them. Wolves don't really have predators. They have enemies, like a human would certainly be something, or a bear. A bear could kill them in a fight for the same kill. But other than that, wolves don't have predators.

Penguins generally do not exhibit fear of humans, as they have not evolved to perceive us as predators. In many areas, they are accustomed to human presence and may approach people out of curiosity.
