What Are the Adaptations of Ermine?

According to Alaska Kids, there are several adaptations of the ermine, such as their flexible bodies, warm fur and camouflage coats. This allows them to not only hunt but also to survive in harsh environments.

Ermines are adapted to their environment. One such adaptation is their sinuous, flexible body. This allows them to reach the burrows of their prey, which include rodents, birds and insects. When it attacks prey, it bites the back of the neck and severs the spinal cord. An ermine will even attack animals larger than itself. Besides attacking prey, the ermines' claws aid them in other ways, such as in digging and climbing. This is especially important because ermines living in trees and cracks of rocks. Another adaptation is their fur. Ermines live in cold environments, such as Alaska, the northern United States and Canada. To help them survive in the cold, they have thick, soft coats of fur. This is doubly important because ermines have neither the body fat nor hibernation capabilities to see them through long winters. These same coats of fur also aids in their concealment. During the summer their fur is brown, but once winter starts, their coats turns white. This helps them to blend into the environment so that they can elude predators and hunt prey.
