The Kirk’s dik-dik (Madoqua kirkii)

The Kirk’s dik-dik (Madoqua kirkii) is a species of dik-dik antelope, which are among the smallest antelopes in the world. The Kirk’s dik-dik is the largest species in the genus, standing between 35 and 45 cm (14-18 in) tall and weighing between 3.8 and 7.2 kg (8.4-15.9 lb). Females are slightly heavier than males, weighing about 0.4 to 1 kg (0.88-2.20 lb) more. While males have horns, which are about 7.5 cm (3.0 in) long, corrugated, and inclined backward. It is native to Eastern and Southern Africa. They are herbivores that can reach speeds of up to 42 km/h (26 mph). Their proboscises are an adaptation for surviving in the arid regions of eastern Africa, as they contain an enlarged nasal chamber supplied with a large amount of blood, which is cooled by rapid nasal breathing before being pumped back into the body. This also results in minimal water loss in exhaled air. They exhibit nocturnal or cathemeral behavior and seek shade during the day to rest during the hottest hours.

The green rosella (Platycercus caledonicus)

The green rosella or Tasmanian rosella (Platycercus caledonicus) is a species of parrot native to Tasmania and the Bass Strait islands, and it is the largest species in the genus Platycercus. Measuring about 29–36 cm (11–14 in) in length, it has a wingspan of 44–54 cm (17–21 in). Males are heavier than females, with an average weight of around 150 g (5.3 oz).

They are found in a wide variety of habitats with some form of tree cover, up to 1,500 m (5,000 ft) above sea level. The green rosella is predominantly herbivorous, feeding on seeds, berries, nuts, and fruits, as well as flowers, but it may also feed on larvae and insects.

The breeding season lasts from September to January, and their nesting sites are mostly located in tree hollows. They are widely distributed throughout Tasmania and are classified as Least Concern by the IUCN. However, the King Island subspecies has been classified as Vulnerable because its population has declined following the clearing of much of its habitat on the island.

The Philippine slow loris (Nycticebus menagensis)

The Philippine slow loris (Nycticebus menagensis) is an arboreal and nocturnal primate of the suborder Strepsirrhini, which also includes lemurs, galagos, and pottos. It is native to the northern and eastern coastal areas of the island of Borneo, as well as the Sulu Archipelago in the Philippines. It is found at altitudes ranging from 35 to 100 meters (115 to 328 feet), in primary and secondary lowland forests.

It weighs between 265 and 300 grams (9.3–11.5 oz), making it one of the smallest slow loris species in the world. Like other slow loris species, it has a gland located near its elbow that produces an oily toxin used for defense. There is little information about its diet, but it is suspected to be one of the most insectivorous slow loris species, although there are records of it feeding on the gum of woody plants.

Factors such as capture for the pet trade and extensive habitat loss have caused its populations to be classified as Vulnerable by the IUCN.

The southern brown bandicoot (Isoodon obesulus)

The southern brown bandicoot (Isoodon obesulus) is a nocturnal, solitary, and omnivorous marsupial found mainly in southern Australia. Males of the species are, on average, 50 cm long and weigh up to 1.2 kg, while females measure 40 cm and weigh no more than 1 kg. They inhabit open forests, shrublands, and heathlands. They are very important to the environment because, when they dig through the soil in search of food, they increase nutrient cycling, water penetration, and soil aeration.

In the 1800s, the southern brown bandicoot was considered one of the most common native mammals in southern Australia. However, it experienced a population decline following European colonization, and it currently has a fragmented distribution. Factors such as the introduction of invasive predators, habitat loss, and the isolation of populations due to roads are challenges that southern brown bandicoot populations face today.

The Caribbean roughshark (Oxynotus caribbaeus)

The Caribbean roughshark (Oxynotus caribbaeus) is a small species of shark that reaches about 50 cm (20 inches) in length. It lives in deep waters, between 400 and 450 m (1,310 and 1,480 feet), in the western Atlantic Ocean, particularly near the bottom of the Gulf of Mexico and the Caribbean Sea. Its teeth have unusual shapes, with spear-shaped upper teeth and blade-shaped lower teeth, which are adapted for feeding on invertebrates and fish. This shark species lives at depths where deep-sea fishing operates, which may have a negative impact on a shark population that is already uncommon and poorly understood.

The fish-scale gecko (Geckolepis maculata)

The fish-scale gecko (Geckolepis maculata) is a species endemic to Madagascar and the Comoros archipelago. It has an insectivorous diet and arboreal, nocturnal habits. A striking characteristic of its genus is the ability to easily detach its scales, a defense mechanism used to distract predators. The predators are left chewing on the detached scales, creating an opportunity for the geckos to escape. After shedding their scales, they need to wait two to three weeks for them to grow back.

The striped hog-nosed skunk (Conepatus semistriatus)

The striped hog-nosed skunk (Conepatus semistriatus) is a species of skunk found in Central and South America. It measures approximately 35–50 cm (14–20 in) from head to tail and weighs around 1.4–3.5 kg (3.1–7.7 lb). It is a nocturnal and solitary animal with an omnivorous diet that inhabits open vegetation areas, such as grasslands and savannas, while avoiding regions with denser forests. Like all other species of skunks, it has perianal glands that produce a highly volatile substance with a very strong and unpleasant odor, which they spray when they feel threatened.

The Tibetan Fox (Vulpes ferrilata)

The Tibetan fox is a true fox species endemic to the high Tibetan Plateau and to Bhutan, China, India, and Nepal. It primarily inhabits semi-arid to arid grasslands of plains and hills at elevations between 3,500 and 5,200 m (11,500 to 17,100 ft), and is occasionally spotted at elevations of around 2,500 m (8,200 ft). These regions are generally far from humans and dense vegetation.

Although its head may appear disproportionately large in relation to its body, this impression is mainly due to its thick fur. Unlike other fox species, the Tibetan fox has a slender skull, an elongated muzzle, and powerful jaws that help it hunt its main prey, plateau pikas, a type of lagomorph.

Although they are not at risk of extinction, they still face threats from hunting for their fur, the presence of stray dogs, which compete with them for prey and can transmit rabies and other diseases to the foxes, and a Chinese government-sponsored program involving the poisoning of pikas.

Orinoco crocodile (Crocodylus intermedius)

The Orinoco crocodile is found only in the Orinoco River basin in Venezuela and Colombia. It has a generalist diet, although it is predominantly piscivorous. It is a large crocodile. Historical reports suggested that males could reach lengths of up to 6.8 m (22 ft 4 in) and weigh more than 900 kg (2,000 lb). Based on these historical reports, it was once considered the largest crocodile in the Americas and the third-largest in the world. Modern estimates suggest that males generally do not exceed about 4.2 m (13 ft 9 in) in length or 450 kg (1,000 lb) in weight.

The species is currently highly threatened with extinction, largely due to excessive hunting for its skin from the 1940s to the 1960s. Although it was granted protected status in the 1970s, its wild population remains critically small. Estimates range from around 250 to 1,500 individuals in the wild. Other threats include the illegal trade in its offspring, pollution, habitat degradation, and competition with the region’s abundant population of spectacled caimans.
