Physical Adaptations

The color of a grey wolf helps it survive by blending the wolf into its surroundings and letting it sneak up on small prey. Another adaption is that they're bite pressure has been measured at 1500 psi, this help these animals to kill prey. Wolves have strong leg muscles that help them pace themselves and keep up with fast prey like moose. Another adaption that grey wolves have are their teeth, they help wolves cut through tough animal hides. The last adaption is that wolves have strong noses, meaning that they can smell other wolves and prey from a distance. This help them so that they know when food is near or when a dangerous pack is nearby.

Behavioral Adaptations

Wolves hunt and live in packs. Packs are an adaptation because they make hunting easier and protecting their young effectively and safely. Wolves have a strong sense of smell, their sense of smell is 100 times better then humans. This helps them hunt prey. In each pack there are ranks that show who is in charge and who eats first, this is important so that the wolves do fight among themselves for food of for mates. Wolves howl to each other when they should assemble for hunts, and to communicate with other packs that that is their territory. This is important so that there are no fight. Wolves are partly nocturnal so that they can sneak up on prey at night
