PRESENTATION OUTLINE
Arctic hares have thick fur that becomes white in the winter. This helps them hide from their predators, such as foxes. They are omnivores. They can go up to 40 mph, and are larger than rabbits.

In the spring, their coat changes to a blue-gray color to imitate rocks and vegetation. They make holes in the snow to stay warm. Their low surface area to volume ratio also helps them stay warm.

Females have one litter per year, born in spring or early summer. Litters usually consist of two to eight leverets. They resemble their parents by September. In the winder, they eat woody plants, moss, and lichens. In other seasons, they eat berries, buds, leaves, roots, and bark. Native Americans hunt them for their fur, which they use for cloth.

Cnidarians and arctic hares are both mobile. They are prey and don't hibernate. They have bilateral symmetry. Cnidarians live in water. They have no fur, while arctic hares are covered in fur. They have tentacles, and are polyps or medusas. They are also invertebrates.

Flatworms and arctic hares are both mobile. They are consumers and they both have a muscular system. However, flatworms have absent guts. They have no fur or feet. They are parasites who live inside people.

Segmented worms and arctic hares are comsumers. They both have special ways of hiding from their predators and dig through the Earth. Segmented worms have no fur. They have coelom, and can live underwater. They have long bodies with no feet.

Molluscs and arctic hares both have feet. They are consumers and are prey. They both dig through the earth. They hide from their predators. Molluscs live in the water. Instead of fur, they have hard shells. They have mantles, ctenidia, and a radula.

Roundworms and arctic hares reproduce sexually. They are consumers and have a complete digestive system. They both have bilateral symmetry. Roundworms are parasites. They live inside other animals and lay eggs. They have a cuticle and pseudocoelom.

Echinoderms and arctic hares are both mobile. Sea stars and arctic hares both have bilateral symmetry, while other Echinoderms do not. They are consumers and reproduce sexually. Echinoderms are very slow, unlike arctic hares. They live underwater. Most Echinoderms don't have spines. Almost all Echinoderms have radial symmetry.

Arthropods and arctic hares are mobile. They are consumers who have appendages. They have their own defense mechanism to keep away predators. Some arthropods have wings, unlike the arctic hare. They have an exoskeleton and segmented body parts. Some arthropods can live underwater. They can have antennae.

Lampreys and arctic hares both have an endoskeleton and a heart. They are consumers who have teeth. Lampreys, unlike arctic hares, and gills and live underwater. They are not anmiotes. They have a swim bladder that they use to rise and lower in the water.

Sharks, rays, and arctic hares have an endoskeleton. They are consumers. Sharks and rays have gills and live underwater. They have no bones. Their bodies are made of cartilage. They are not amniotes.

Bony fish and arctic hares have bones. They are prey who use special defenses to protect themselves against predators. Bony fish have gills and live underwater. They are covered with scales and have a swim bladder. They are not amniotes.

Amphibians and arctic hares are both tetrapods. They have lungs to live on land. Frogs, as well as hares, use their powerful hind legs to jump. Frogs are usually green and lose their tail when they become adults. They are born in the water as tadpoles, while arctic hares are born on land and keep their tails.

Birds and arctic hares are amniotes. They are endotherms and have an endoskeleton. They are in the same phylum as arctic hares. Birds have feathers and wings. They have beaks, unlike hares. They have hollow bones and air sacs to help them fly.

Reptiles and arctic hares both have lungs and an endoskeleton. They are both amniotes. Arctic hares have an upright stance, while reptiles sprawl. Reptiles are semi-aquatic and have dry plates. They have three-chambered hearts.

Arctic hares and dogs are both covered in fur. They have four-chambered hearts and are amniotes. However, they have different body structures. Their ears are different. Arctic hares have long ears that round on the top. They also have different social behaviors.
