Cheetahs are the fastest land animals on Earth, capable of reaching speeds of up to 75 mph. Cheetahs have around 2000 spots, which are thought to help with camouflage in their natural habitat. Cheetahs don't roar, but they can meow, purr, and make other sounds like chirps. Only male cheetahs are social, forming coalitions of 2-3 to defend territory. Cheetahs hunt during the day, unlike many other big cats that are nocturnal.
They're the largest animal on Earth: Blue whales can grow up to 100 feet long and weigh over 200 tons, exceeding even the largest dinosaurs. A blue whale's heart can weigh as much as a car and its heartbeat can be heard from two miles away. The tongue of a blue whale is so big that a whole football team could stand on it, and it weighs as much as an elephant. Blue whales are the loudest animals on the planet, with cries that can be louder than a jet plane and can be heard hundreds of miles away.
Blue whales gulp enormous amounts of water, then push it out through baleen plates, filtering out tiny krill which they then swallow.
Sloths are slow, but strong: They move very slowly, but they have a surprisingly strong grip and are capable of holding onto tree branches with incredible force, says the World Animal Protection US. Algae grows on their fur, providing them with camouflage and potentially helping to ward off parasites. While slow on land, they are actually quite fast and agile in the water, moving three times faster than they do on land. It takes sloths a long time to digest their food, with some studies suggesting it can take up to a month to digest a single leaf, says BBC. Sloths are known for their sleepiness, with some individuals sleeping for up to 20 hours a day.
Giraffes are the tallest land animals on planet Earth. Fully grown giraffes stand at 4.3 – 5.7 metres tall. That’s taller than three men standing on each other’s shoulders! Baby giraffes might look tiny compared to their mums, but they’re as tall as the average man when they’re born. They use their long necks to help keep a lookout for predators. Their eyes are higher up and so better able to spot any approaching predators on the wide, open grasslands. Prowling predators can easily disguise themselves in thick forests, so the flat land is better for giraffes. Giraffes prove that you can be super tall and super fast! They reach speeds of up to 60km/h over short distances. The colour of their tongue is dark blue. No two giraffes have the same pattern. Their patchwork coats also vary depending on their species.
Elephants are the largest land animals. They are known for their impressive size and weight, making them a truly awe-inspiring creature. Elephants have amazing communication skills. They can communicate through a variety of methods, including trumpeting, using body language, and even sending signals through the ground. Elephants have excellent memories. The saying "an elephant never forgets" is based on some truth, as they have a remarkable ability to remember places, people, and events. Elephants have a unique sense of smell. They can smell water from miles away and use their trunks to pick up objects, lift food, and even communicate. Their skin is incredibly thick, which helps protect them from the sun and other environmental factors.
They are the smallest birds in the world: Hummingbirds are renowned for their minuscule size, with some species like the bee hummingbird weighing only two grams. Hummingbirds are the only birds that can fly backward, enabling them to hover, turn, and stop instantaneously. Hummingbirds have a rapid metabolism, requiring them to eat frequently, often every 10-15 minutes, and they can consume up to twice their body weight in nectar daily. A hummingbird's heart can beat up to 1,200 times per minute and is a significant portion of their body weight. Hummingbirds utilize spider webs as a binding agent and structural support for their nests, according to Wild Birds Unlimited.
Gorillas are the largest primates on Earth: Adult male gorillas can stand over 6 feet tall and weigh up to 485 pounds, making them the biggest primates in the world. Just like humans have fingerprints, gorillas have unique noseprints that scientists can use to identify individual gorillas. They primarily eat plants, including leaves, stems, bamboo shoots, and fruits, according to the World Wildlife Fund. Adult males, known as silverbacks, are 9 to 10 times stronger than humans and can lift objects weighing up to 2000kg. Gorillas are intelligent and resourceful. National Geographic Kids says they've been observed using sticks to gauge water depth and for balance.
They have a high brain-to-body ratio: Crows, ravens, and parrots have the biggest brain-to-body size ratios of all living bird species. Crows can use sticks, rocks, and other objects to gather food or solve problems, making them one of only a few species known to do so. Crows have been observed to recognize human faces and scold people they associate with danger. Crows can mimic the sounds of other animals, including human speech. Crows have been seen gathering in large groups around the dead, possibly to learn about potential dangers.
Octopuses are known for their intelligence and problem-solving skills, with the highest brain-to-body mass ratio of any invertebrate. They can change their skin color and texture in seconds to perfectly blend into their surroundings, thanks to millions of tiny pigment-containing cells called chromatophores. Octopuses have blue blood, not red like humans, due to the presence of copper-rich hemocyanin. They also have three hearts: two to pump blood to the gills and one to circulate it throughout the body. All octopuses have venom, which they inject into their prey using a beak to paralyze it. Some species, like the blue-ringed octopus, have a potent venom that can be deadly to humans. Octopuses have the ability to regrow lost arms and tentacles.
Dragonflies have been around for a very long time, dating back over 300 million years. Even though they are some of the earliest winged insects, they have evolved to become amazing hunters. Dragonflies are known for their incredible flying abilities. They can fly in any direction, including backwards, and can even hover or fly straight up and down. Dragonflies spend most of their lives as nymphs, or larvae, underwater, before transforming into the flying adults we know. These aquatic nymphs can live for up to two years, feeding on other insects, tadpoles, and even small fish. Dragonflies are fierce hunters, consuming a wide variety of insects, including mosquitoes, flies, and even other dragonflies. They can catch their prey in mid-air with their legs, creating a basket-like structure to hold it. Dragonflies have amazing eyesight thanks to their large, compound eyes. These eyes are made up of thousands of lenses and allow them to see almost all around them, giving them a nearly 360-degree field of view

Colossal squid are the largest known invertebrates on Earth, exceeding even giant squid in size and weight. They can grow to be up to 46 feet long and weigh over 1,000 pounds. They possess the largest eyes in the animal kingdom, measuring around 11 inches in diameter. These giant eyes help them see in the dark depths of the ocean. Colossal squid have sharp, hook-like structures on their tentacles, which they use to capture prey. These hooks can be quite formidable, with some being swivel hooks and others three-pointed. Colossal squid are thought to use bioluminescence to attract prey, and they might also use it to camouflage themselves in the deep sea. Like other squid, colossal squid have three hearts: two branchial hearts that pump blood to the gills and one systemic heart that pumps blood to the rest of the body.

Dolphins can sleep with only half of their brain at a time, keeping one eye open and the opposite half of their brain alert to ensure they can breathe and stay safe. Certain dolphin species have been observed using sponges, shells, or even rocks to aid in hunting or foraging, showcasing their intelligence and problem-solving skills. Some dolphin species can reach speeds of up to 37 miles per hour, using their streamlined bodies and powerful tails for efficient swimming. Each dolphin in a pod has a distinctive signature whistle that is used to identify themselves and communicate with others. They live in groups called pods, which can range from a few individuals to over a thousand, and they demonstrate strong social bonds and cooperative behavior.
They are the largest land carnivores on Earth. Polar bear fur appears white, but it's actually transparent and hollow, reflecting light and making them appear white. Their skin is also black, absorbing heat from the sun. While they live on land, polar bears are classified as marine mammals because they depend on the sea ice for hunting and are closely tied to the marine ecosystem. They are incredibly strong swimmers, using their large paws like paddles to navigate the icy waters. Polar bears have an extraordinary sense of smell, allowing them to detect prey, like seals, from a great distance.
