Musk-oxen huddle together to share warmth in the winter. They conserve energy by standing still in bad weather. Very low rating. Very high rating. Nit has no teeth but a hard horny rim on jaws for biting off pieces of plants.
Porcupines turn their backs on predators and swing their powerful tails toward the attacker.
It's small compared to its predators. Low rating here. It also has a behavior that contributes to the effect of the camouflage. It sits very still on the flower and waits for hours without moving to grab an insect. When attacked it puts up its spiky forelegs instead of running.
