In the Tundra, animals need to have thick fur to survive the cold. Many animals in this biome also have white fur or feathers to blend into their surroundings. These traits will help them survive the cold and escape from predators.
In Taiga Forests, animals have thick natural colored fur to stay warm and blend in with their surroundings. Many also hibernate to conserve energy in the winter.
The Grasslands are home to many herbivores that feast on the plentiful long dry grass. These animals are adaptable to varying temps. They also have coloring that blends in with the grass.
Animals in the Dry or Desert biome need to have the ability to conserve water which is scarce in the desert as it suffers droughts. They also feed on the few types of plants such as cacti and small animals such as insects to survive in this climate.
In the Freshwater biome, many animals must use less oxygen and often take it in through gills. Animals such as ducks will have webbed feet and fish will have fins for pushing through water in order to swim. These animals bodies also do not need salt.
In the Marine Biome, salt from minerals fills the ocean. The animals have adapted to this salt and now need it to survive. Many species have tentacles or suction for grasping and feeding in their ocean home. As of plants, many still use photosynthesis.
