General and Unique Behaviors: They are solitary animals that hunt both on land and in water. Lifespan: 20-30 years Key Adaptations: They have developed hollow fur that allows them to remain buoyant in water. They also have light fur to let them camouflage in the snow. Similar Species: Brown bears, black bears Other Information: These creatures could be extinct within the next 30 years if climate change doesn't stop. Siberian Tiger: Classification:
Kingdom- Animalia Phylum- Chordata Class- Mammalia Order- Carnivora Family- Felidae Genus- Panthera Species- P. tigris Specific Habitat: They live primarily in eastern Russia's birch forests. Mating Habits: Females usually give birth to litters of two to six cubs, which they raise for 2 to 3 years before leaving them to fend for themselves. General and Unique Behaviors: Tigers live alone and are aggressively protective of their territory. They will scent-mark large areas to keep other tigers away, and they often hunt at night. Lifespan: 10-15 years Key Adaptations: Their stomachs are specially made so that they can consume 20-30 lbs. of meat per day. Their white fur also allows them to blend in with snow. Similar Species: Panthers and other wildcats Other Information: A tiger's stripes are a lot like human fingerprints, variable enough that they can be used to identify one tiger from another. Caribou: Called reindeer in Europe and caribou in Alaska and Canada, these animals have large, concave hooves that make them well-adapted for the Siberian tundra. They often weigh in between 200-400 lbs. and have to keep moving in order to find adequate sources of food. Large herds of caribou will migrate between summer and winter and have the ability to consume lichens in the winter. Lemmings: Natives of the arctic, these rodents look like guinea pigs but often only grow to 5 inches long. They live around sedges and grasses in order to maintain a sustainable food source, and these plants also grow high enough to keep them hidden from predators. These little creatures also have a tendency to accidentally drown themselves in the ocean, thinking they can swim across it to find food. Snowy Owls: These are iconic natives in the tundra. Known for their white plumage that gets whiter with age, these owls will give birth to a clutch of 3 to 11 eggs and will remain highly protective of their offspring until they're grown. Their primary sources of food are lemmings, as the average adult male will consume 1,600 lemmings a year. Shrews: Shrews are mouse-sized animals with long snouts. Unlike mice, however, these creatures are insectivores, but they also supplement their diets with vegetable matter. Most shrews need to consume 200-300% of their body weight a day in order to survive. Tundra Voles: They prefer sedge meadows with abundant cover and vary in color from dark brown to light grey. The males in their species is larger, and they feed solely on vegetation from sedges. prefers mesic sedge meadows with abundant coverpreferporeprwe Arctic Hare: These animals live near vegetation, where there is a stable food source. Their coats change from brown to white in the winter to keep them camouflaged from other predators. |
