explanation[1]="American wood frogs literally freeze themselves in winter and thaw out in spring. They go through a process called cryptobiosis, in which their cells freeze and their heart stops beating until the snow melts and temperatures warm." 
explanation[2]="Emperor penguins live and breed in the coldest and windiest conditions on Earth! They have dense layers of feathers and thick fat under their skin to insulate them from cold water and air temperatures. While Emperors do not stand on their toes, they do stand on their heels to limit contact of their feet with the ice. They also do something that no other penguins do: huddle together in large groups to protect themselves and their chicks from winter weather!"
explanation[3]="Monarchs migrate over 3,000 miles each fall! They spend their summers in Canada and the northern United States and fly south for the winter to avoid cold temperatures and winter storms. Other types of butterflies and moths fatten up with nectar in the fall and spend the winter tucked into cracks in bark, buildings and hollow trees or overwinter as eggs or pupae in cocoons buried underground or attached to plants."
explanation[4]="Even though they are cold-blooded like other insects, honeybees are well-adapted to the cold. Their workers survive by eating the honey they made during summer and fall. This allows their bodies to generate heat. Working together, the colony can maintain its hive temperature well above freezing."
explanation[5]="Even though it is winter, you can still watch for wildlife by bundling up with a coat, hat and gloves and going for a walk in the woods with family and friends. If the ground is muddy or snowy, you might even be able to track animal footprints. If it is too cold to go outside, you can still see birds, squirrels and other wildlife by looking outside your window."
