Ever wondered about the quirky side of nature? Here are 10 cool animal facts that might surprise you.

Elephants are the largest land animals in the world. The African elephant can weigh up to 14,000 pounds (6,350 kilograms) and has a unique trunk that serves as a nose, an arm, a hand, and a multi-purpose tool. Elephants have a highly developed brain, exhibit behaviors associated with grief, learning, and memory, and are known for their complex social structures.

Honeybees communicate through a dance known as the "waggle dance." When a scout bee finds a new source of food, it returns to the hive and performs a dance that varies in duration and direction to communicate the distance and location of the food source relative to the sun.

Octopuses have three hearts and blue blood. Two hearts pump blood to the gills, while the third pumps it to the rest of the body. Their blood is blue because it is copper-based, which is more efficient in transporting oxygen in cold and low-oxygen environments.

The cheetah is the fastest land animal, capable of running up to 75 mph (120 km/h) in short bursts covering distances up to 1,500 ft (460 m), and has the ability to accelerate from 0 to 60 mph (97 km/h) in just a few seconds.

Bats are the only mammals naturally capable of true and sustained flight. Their wings are made of a thin membrane stretched over an elongated finger structure, allowing them to maneuver with great agility.

The blue whale, the largest animal ever known to have existed, has a heart the size of a small car and during the main feeding season, it consumes approximately 4 tons of krill a day.

Kangaroos use their tails for balance while hopping and as a third leg to form a tripod with their two hind legs when moving slowly. They can't walk backwards and are the only large animals to use hopping as their primary means of locomotion.

Polar bears have black skin under their white fur, which helps them absorb sunlight and stay warm. Their fur is translucent, not white, and it scatters and reflects visible light, making them appear white or yellow.

Tardigrades, also known as water bears, can survive in extreme environments that would kill almost any other animal. They can withstand temperatures from just above absolute zero to well above the boiling point of water, pressures about six times greater than those found in the deepest ocean trenches, radiation doses that would kill other animals, and the vacuum of space.

The axolotl is a salamander from Mexico that can regenerate its limbs, heart, and even parts of its brain and spinal cord. Unlike most creatures, axolotls do not undergo metamorphosis and remain aquatic their entire lives.
