lianna [129]

For example, snow-show hare and ermine live in taiga and their fur color changes with environmental conditions. To effectively camouflage, their fur is white during the winter. That helps them blend into the snow. In the summer, where there is no snow, their fur is brown and similar to the soil color. This way<span> it is more difficult for their predators to spot them.</span>
