Fun Fact: Elephant shrews can run at speeds of up to 28 km/h (17 mph) and have a unique way of communicating through scent marking and vocalizations! 🎶💨

Siamang (Symphalangus syndactylus) - the largest, strongest, and most vocal of the gibbon family. Their loud "singing" can be heard up to 3 kilometers away through the forest. Their fur is long, shaggy, and entirely black, except for reddish-brown eyebrows.

Unlike smaller gibbons, siamangs are excellent swimmers, using a unique monkey breaststroke - their second and third toes on the hind feet are even connected by webbing. Gibbons are the only primates that have mastered moving through the trees using their arms, swinging from branch to branch like Tarzan.

Every morning, siamangs greet the sunrise with a loud chorus. The "concert" usually starts with a duet between an adult male and female, joined by the rest of the family. The male produces a low, bass-like roar using a large throat sac, while the female and adolescents "sing along" with shrill barks and joyful screams. The "cantata" lasts about 15 minutes.

Fun Fact: Siamangs are known for their unique "brachiation" - a form of movement where they swing from tree limb to tree limb using only their arms. This allows them to travel quickly and efficiently through the forest canopy.

Marbled Polecat (Vormela peregusna) – a small carnivorous mammal from the weasel family, inhabiting the steppes and deserts of Asia, as well as eastern Europe. Resembling a ferret but smaller, with a body length of 29-38 cm and a tail of 15-22 cm. Adults weigh between 370-730 g.

Marbled polecats thrive in dry, treeless areas like steppes, semi-deserts, and deserts. Occasionally, they can be found on grassy plateaus and even in mountains up to 3000 m. Today, many live in parks, vineyards, and even human settlements.

Fun Fact: Marbled polecats are known for their unique defense mechanism – they release a foul-smelling liquid when threatened, similar to skunks!

Did You Know? Their population declined sharply due to agricultural expansion, leading to their inclusion in the Red Data Book. 🐾

Brush-tailed Rock Wallaby (Trichosurus vulpecula)

The brush-tailed rock wallaby, also known as the common brushtail possum, is native to Australia, New Zealand, and Tasmania. It's called "brush-tailed" due to its long, bushy tail.

Fun Fact: These marsupials have a prehensile tail, which they use for balance and gripping branches while climbing.

Appearance: They have a pointed snout, large ears, and a grey or brown coat. Albino brush-tailed rock wallabies also exist. They weigh between 1.2 to 4.5 kg (2.6 to 9.9 lbs) and have a body length of 32-58 cm (12.6-22.8 in), with males being larger than females.

Habitat & Diet: Nocturnal creatures, they spend their days resting in tree hollows or nests called dreys. They feed on leaves, fruits, and berries.

Predators & Conservation: Their main predators are birds of prey and monitor lizards. Once hunted for their valuable fur, they are now a protected species.

Their fur was once exported as "Australian opossum" or "Adelaide chinchilla."

Can you imagine a hornless, saber-toothed deer no taller than half a meter at the withers and not heavier than a pound weight? Neither could I. Yet, such a marvel exists and is oblivious to the fact that it's hard to believe!

This is the water deer (Hydropotes inermis), our border guards nicknamed it the marsh goat due to its tusks—though these animals are not related.

These deer live north of the Yangtze River valley in Eastern China and Korea. In 2019, they were spotted in Russia—within the national park "Land of the Leopard" in Primorsky Krai, thanks to camera traps.

The lifestyle of this mysterious deer is poorly understood. It lives alone or in pairs in grassy thickets along river and lake banks and in marshes, primarily active during the day, and is very cautious, which is not surprising given its tiny size. 🦌💦

Sloths (Folivora) can run, but very, very slowly! 🐾 Not because they're lazy, but due to their slowed metabolism. It's surprising these little creatures have survived to this day—both wild cats and anacondas, as well as harpy eagles, wouldn't mind snacking on them!

Most predators only become a threat to sloths when they descend to the ground, which they rarely do. This is the secret to the survival of smaller sloth species during the extinction of larger ones—they can hang from thin branches where predators can't reach them.

Since sloths don't make sudden movements, they don't need strong muscles or a powerful heart to supply those muscles with blood during exertion. A sloth's heart mass is only 0.3% of its body mass, and its muscle mass is 25%. By both measures, sloths are 1.5 to 2 times inferior to humans—who, in turn, are not record-holders themselves. 💙

Saguinus Tamarins – Small, Colorful Monkeys of South America

Saguinus tamarins are tiny, vibrant monkeys from the family Callitrichidae, native to South America. Their striking appearance makes them unforgettable!

These primates are among the smallest in the world, with bodies just 19-35 cm long, but their tails are even longer (20-40 cm). They weigh only 300-400 g. Tamarins stand out with their unique, colorful fur, which is thick and soft, with a wide range of hues.

Their small size and strong, grasping limbs, along with their long tails, help them climb to the top of the tallest trees to enjoy ripe fruits. Tamarins prefer warm, dry climates and struggle with sudden weather changes, cold, and humidity.

Fun Fact: Tamarins are known for their complex social structures and cooperative breeding, where multiple family members help raise the young! 🌴🐒

Miniature Horses: Tiny but Mighty!

Miniature horses, belonging to the Equus genus, are known for their small stature (up to 86 cm at the withers) and a build typical of riding horses. Unlike ponies, they have proportionate limb length and a format characteristic of riding horses.

Despite their delicate appearance, they are far from being fragile. With proper shelter and a small amount of hay and concentrate feed, they thrive year-round on pasture. They can easily withstand winter cold, as they grow thick fur. However, like larger horses, they should be protected from drafts.

Interestingly, miniature horses can even be kept indoors as a substitute for dogs. Special diapers (Pampers Active Pony) and boots (to muffle hoof sounds) have been developed for this purpose. However, remember that they need exercise and movement.

Wallaby Petrogale is often confused with kangaroos - all kangaroo-like marsupials look very similar and mostly differ only in size. The term "kangaroo" is often used to refer to any member of the family. In reality, kangaroos are the largest members of the kangaroo family, while the smaller ones are wallabies.

These marsupials can leap up to 10 meters in length and 2 meters in height. Their images appear on ancient rock paintings by Australian Aboriginals, dating back 18,000 years!

Like large kangaroos, wallabies have a pouch where the young spend the first months of their lives. Baby wallabies leave the pouch and become independent only a year or a year and a half after birth.

Wallabies are found in Tasmania, New Guinea, and the Bismarck Archipelago. They have also been introduced to New Zealand and the British Isles (Isle of Man).

Philippine Tarsier (Tarsius syrichta) - a tiny primate, endemic to the Philippine archipelago, and endangered.

Once widespread in Europe, Asia, and North America, tarsiers now only inhabit remote corners of the planet.

Their size is small, with an adult's body no larger than the width of a human hand, about 100 mm. The tarsier's tail is longer than its body. The average weight of males is 134 g, and females 117 g.

The first thing that catches the eye is their enormous eyes, adapted for hunting in the night forest. The round head of a tarsier can turn more than 180 degrees in both directions, allowing it to easily look behind itself. Their ears are also very mobile, almost always in motion. The fingers on both the front and hind limbs are long and well-developed. The tips of the fingers are flattened, forming pads designed for climbing tree branches.

Fun fact: Tarsiers have the largest eyes relative to their body size of any mammal, with eyes that are bigger than their brain!

Gaur (Indian Bison) - Bos gaurus

The gaur is a rare and relatively unknown even-toed ungulate, sharing the title of the largest wild bull on the planet with the bison.

Old males can reach record lengths of 330 cm and 220 cm at the withers! Weight can reach a ton, and according to some data, up to one and a half tons. Females are about a quarter smaller.

Horns average 90 cm in length and are curved upwards in a crescent shape.

Once the range of gaurs covered almost all of South and Southeast Asia: from the Indian subcontinent to Indochina, Malaysia, China, Nepal, and Bhutan. Gaurs are still found there, but their populations are very small and scattered. These bulls inhabit humid evergreen forests, preferring hilly areas with sparse tree cover and avoiding thickets.

Fun Fact: Gaurs are known for their impressive strength and agility, despite their massive size. They can clear jumps of up to 1.5 meters in height! 🌿🐂

Koalas (Phascolarctos cinereus) are known to everyone, here are some interesting facts about these amazing animals.

Members of the expedition that discovered Australia didn't notice koalas. They were first mentioned by a servant of the local governor, who encountered these unusual animals during a mountain hike almost 30 years after the continent's discovery.

The weight of an adult koala, depending on gender and habitat, ranges from 5 to 14 kg.

Their gripping fingers, with a unique structure, allow koalas to not only climb trees but also sleep while clinging to the nearest branch or trunk. If necessary, a koala can hang for quite a long time even on one paw, like a sloth.

The weight of a koala's brain is only 0.2% of the animal's body mass. Scientists have discovered that the brains of koala ancestors filled the entire skull, but due to their leaf-based diet, it gradually degenerated to its current state.
