Pygmy Hippopotamus (Hexaprotodon liberiensis or Choeropsis liberiensis)

Discovered by Europeans in 1911, the pygmy hippopotamus is one of only two extant hippopotamus genera: the common and the pygmy. Today, all modern members of this family are found exclusively in Africa.

While large hippos can weigh up to three tons, adult pygmy hippos typically weigh around 300 kg. They stand about 70-80 cm tall and have a body length of around 160 cm.

These shy creatures prefer quiet, secluded spots to avoid predators. They often inhabit small swamps or slow-moving, overgrown rivers, taking refuge in abandoned burrows, which they enlarge to fit their size—though they cannot dig their own.

Fun Fact: Pygmy hippos are excellent swimmers and can hold their breath underwater for up to five minutes! 🐊💦

Wombats have a unique backward-facing pouch, which is why you might see a two-headed feeding creature like this!

Wombats dig intricate underground labyrinths with tunnels up to 20 meters long and 3.5 meters deep. Their territories range from 5 to 25 hectares, and they aggressively defend them with sharp claws. They mark their territory with excrement, and their weight can reach up to 35 kg, with a body length of 70 to 130 cm.

Wombats are among the most water-efficient mammals after camels, needing only 22 ml of water per kg of body weight per day. They feed on young plant shoots, tree bark, roots, fungi, and berries. Their metabolism is very slow, taking up to 14 days to digest food.

Fun fact: Wombats have a cube-shaped poop, which helps prevent it from rolling away and marking their territory effectively! 🐾

Indian Giant Squirrel (Ratufa indica) is astonishing with its size: body length is 35-40 cm, and tail length is 50-60 cm. It weighs up to 3 kg.

The fur of the giant squirrel is remarkably dense and shiny. Its color varies widely from light purple to dark red, cream, or brick-brown shades. Each community of giant squirrels has a unique fur color, and the pattern can help determine the origin of each animal.

Giant squirrels prefer to live in the upper layers of the forest, with jumps sometimes reaching 6 m. These creatures are very cautious and can skillfully camouflage. Their natural enemies are large cats, martens, arboreal snakes, and birds of prey.

Just a few decades ago, giant squirrels were mercilessly exterminated for their beautiful fur. Today, they are listed as a vulnerable species and are included in the Red Book.

Fun Fact: Giant squirrels are known for their unique nesting behavior.

They build multiple nests, called "dreys," in different trees to confuse predators and protect their young. 🐿️🌳

Kiwi (Apteryx) - Flightless Birds from New Zealand

Kiwis are unique, flightless birds that resemble mammals more than birds. They move on the ground, have fur-like feathers, and a body temperature of 38°C.

Depending on the species, kiwis vary in size, weighing between 1.4 to 4 kg. They have a long, thin beak that can reach lengths of 95–120 mm.

Although kiwis cannot fly, they do have wings, but they are tiny, no more than 5 cm, making them hard to notice under their dense feathers.

Kiwis are monogamous birds, forming pairs for 2–3 breeding seasons, or even for life. Fun fact: their eggs are legendary! A female kiwi weighing 2–3 kg can lay an egg weighing 500 g.

Kiwis are long-lived. In the green, damp forests of New Zealand, they can live up to 60 years, if not caught and eaten by local predators.

However, their population is a cause for concern. Predators, introduced by Europeans relatively recently, love to hunt these birds, which have a distinctive smell.

Saiga Antelope (Saiga tatarica) - A Unique Steppe Antelope with a Distinctive Snout

The Saiga antelope is a unique creature that has roamed the Earth for 50,000 to 70,000 years, surviving the Ice Age alongside mammoths. Despite its long history, it is now considered an endangered species, struggling to survive in the modern world.

Standing at 60-79 cm tall and 110-140 cm long, with a 8-12 cm tail, the Saiga is roughly the size of a goat. Weighing between 23-55 kg, this antelope can reach speeds of up to 80 km/h, outpacing cars on rough terrain.

The Saiga's most distinctive feature is its flexible snout, which helps it survive in different seasons. In winter, it warms the air before inhaling, and in summer, it filters out dust from the steppe. 🦌💨

Pygmy Marmoset (Cebuella pygmaea) – an unusual tiny monkey from the marmoset family, inhabiting the tropical forests of Central and South America. What sets them apart from other monkeys is their size – they are the smallest primates in the world.

Weighing less than 100g and measuring just 20-25cm tall, their tail is as long as their body. Unlike other monkeys, their tail cannot grasp but helps them balance when jumping from branch to branch.

Due to their small size, pygmy marmosets must constantly hide, living high up in trees to avoid predators. They sleep in tree hollows and live in large families, with up to six generations.

Pygmy marmosets rarely descend to the ground due to the many dangers there. However, they are curious creatures and can often be spotted near villages.

Fun Fact: Despite their tiny size, pygmy marmosets have a powerful bite force, using their sharp teeth to gnaw holes in trees to find sap and insects to eat.

Serval (Leptailurus serval) - a slender medium-sized cat, a close relative of lynxes and caracals. Among all felines, servals have the tallest legs and disproportionately large, rounded ears relative to their body size. Their head is small, and their tail is short (does not reach the ground). The coat color of servals varies by geographic region - in the mountains, you can even find completely black individuals.

Servals were first mentioned in Ancient Egypt - along with reed and steppe cats, they helped people save themselves from rodents and snakes. Therefore, servals had the status of sacred animals among the Egyptians. To this day, elegant cat statues and even their separate burials amaze archaeologists with their perfection and delicate details.

Servals can grow up to 1 meter in length, and their tail can reach 40 cm. 🐾

Nilgai (Boselaphus tragocamelus) - The Largest Antelope in Asia

The nilgai, standing up to 1.5 meters tall and 2 meters long, is the largest antelope in Asia. Males are larger than females and are the only ones with straight, vertically upright black horns.

In India, these even-toed ungulates were considered relatives of the sacred cow, and hunting them was prohibited, even when their herds damaged crops. Due to the bluish-grey color of males, nilgai are called "Blue bulls," and their Indian name carries the same meaning.

Nilgai primarily feed on leaves, shoots, and grasses. They often stand on their hind legs while eating and rarely visit watering holes, as they get all the necessary moisture from the plants they consume.

In the wild, nilgai live for 12-15 years, but in captivity, they can live up to 21 years.

Fun Fact: 🐄 Nilgai are the only Asian antelopes with a hump on their shoulders, similar to camels! 🐫

Armored Mammals: The Armadillos of South America

Armadillos are fascinating mammals native to South America. While some species can curl up into a ball, not all can. In 2014, an armadillo became the mascot for the FIFA World Cup in Brazil.

There are many types of armadillos. At 14 seconds, you'll see the hairy armadillo, and at 44 seconds, the giant armadillo takes center stage for the rest of the video. There are also three-banded, six-banded, and nine-banded armadillos.

No other modern land mammal has as many teeth (80-100) or longer claws (as long as a human hand) as the giant armadillo. These massive claws are used for digging burrows or hunting ants and termites. The armadillo digs into the ground and uses its long tongue to extract these insects from their narrow tunnels.

In the wild, giant armadillos weigh around 32 kg (up to 60 kg in captivity) and can reach lengths of 1.5 meters, including their tail. 🦔🌎

Okapi: The Enigmatic Forest Giraffe

The okapi (Okapia johnstoni) is a fascinating mix of features, resembling a zebra, deer, and even an anteater, like a puzzle put together wrong. But is it a horse? No! Scientists say it's actually a relative of the giraffe and lives exclusively in the Congo, Africa.

Standing about 1.5 meters tall, the okapi has a noticeably elongated neck, though not as long as a giraffe's. Adults weigh around 250 kg and measure about 2 meters in length. Males have small, giraffe-like horns.

You might wonder, why the anteater resemblance? The okapi's tongue can reach up to 35 cm, allowing this clean-loving animal to easily wash dirt from its eyes and ears.

With large, elongated, and incredibly mobile ears, the okapi keeps them clean to maintain sharp hearing, crucial for detecting predators in the dense forest.

Fun Fact: The okapi's stripes were once thought to help with camouflage, but recent studies suggest they might also play a role in social interactions and communication! 🦒🌿

Numbat (Banded Anteater) Myrmecobius fasciatus

The numbat, a unique marsupial, inhabits the eucalyptus forests of Australia, sharing its home with koalas. Eucalyptus trees frequently shed branches infested with termites, providing a feast for the numbat, which primarily feeds on these insects. The fallen branches also offer the numbat shelter.

Unlike many marsupials, the numbat lacks a pouch. Instead, its young cling to the long, curly fur on the mother's belly. Even the largest numbat weighs just over 500 grams, with a body length of 20–30 cm.

Despite its name, the numbat rarely hunts ants. Its favorite treat is termites, which it catches with its long, sticky tongue, capable of extending up to 10 cm. This tongue is extremely agile and powerful.

The numbat is agile and quick, climbing trees with ease. However, when threatened, it retreats to cover. When captured, it neither bites nor scratches, expressing its displeasure only with grunts or whistles.

Fun Fact: The numbat is one of the few daytime-active marsupial species and is known for its distinctive banded appearance, with light brown and white stripes running across its back.
