Tundra Biome - Coggle Diagram
Tundra Biome
Cold Temperatures
Some animals hibernate during the cold season when plants can't grow. They do this to conserve energy
Carnivorous animals also hibernate when food sources are less plentiful. They come out of hibernation when food sources return in the spring.
Other animals may migrate to environments where plant life and food is more abundant during the colder seasons.

Many animals have thick stores of fat to keep the animals warm and to store energy during periods where food isn't available.
Tundra insects have developed "antifreeze" for their blood. This allows them to stay alive in subzero temperatures
Many animals developed a compact heat efficient body shape. Tundra animals tend to be more compact then their non-tundra counterparts.
Tundra animals develop more slowly than their non-tundra counterparts. Example: Tundra Trout take 10 years to mature while southern Trout take 6 years. This helps the Tundra Trout conserve energy during its development.
Many Tundra insects spend their entire life underground, away from the harsh aboveground conditions.
Different Adaptations
Hooved animals have a split-hoof system, this allows them to not sink into the snow. This also helps with digging so the animals can dig into the ground for plants.
Plant eating species have adapted with different gut bacteria to digest lichen, which has low nutritional value but is abundant in the tundra.
Fur serves as camouflage with many animals changing colors depending on the season. Example: The snowshoe hare develops a thick white coat of fur in the winter to blend in with the snow. However, in the summer the snowshoe hare looses the thick coat and develops a thinner brown coat to blend in with the environment.
Many species have fur on their feet, which is uncommon for animal species.
Examples
Arctic Fox
-
-
Keener sense of smell, better for hunting in the snow.
Circulatory system allows them to keep their body, and importantly their feet, above a freezing point.
Walrus
-
Circulatory system can constrict vessels in the cold water to reduce heat loss, and dilate when warm.
Large tusks help them navigate the icy environment . They use them to hoist themselves or break up ice.
