Elephants are the world’s largest land animal! Male African elephants can reach 3m tall and weigh between 4,000 -7,500kg. Asian elephants are slightly smaller, reaching 2.7m tall and weighing 3,000– 6,000kg.

There are three different species of elephant – the African Savannah elephant, the African Forest elephant and the Asian elephant. Elephants are known for their large ears, tusks made of ivory and their trunks – which are actually a fusion of their nose and upper lip.

Ravens are great at mimicking human speech and sounds.

Ostriches have the largest eyes of any land animal.

Cardinals like to cover themselves in ants.

Some ducks sleep with one eye open.

A dog’s nose print is unique, much like a person’s fingerprint.

Seventy percent of people sign their dog’s name on their holiday cards.

Dogs curl up in a ball when sleeping to protect their organs—a hold over from their days in the wild, when they were vulnerable to predator attacks.

There are over 75 million pet dogs in the U.S.—more than in any other country.

Pandas eat almost nothing but bamboo shoots and leaves. Occasionally they eat other vegetation, fish, or small animals, but bamboo accounts for 99 percent of their diets. Pandas eat fast, they eat a lot, and they spend about 12 hours a day doing it. The reason: They digest only about a fifth of what they eat. Overall, bamboo is not very nutritious. To stay healthy, they have to eat a lot—up to 15 percent of their body weight in 12 hours—so they eat fast.

Pandas' molars are very broad and flat. The shape of the teeth helps the animals crush the bamboo shoots, leaves, and stems that they eat. They can chomp on bamboo up to one-and-a-half inches thick. To get the bamboo to their mouths, they hold the stems with their front paws, which have enlarged wrist bones that act as thumbs for gripping. A panda should have at least two bamboo species where it lives, or it will starve. A scarcity in bamboo threatens the already limited panda population.

While other birds have wings for flying, penguins have adapted flippers to help them swim in the water.

The Galapagos Penguin is the only penguin species that ventures north of the equator in the wild.

No penguins live at the North Pole.

Penguins eat a range of fish and other sealife that they catch underwater.
