Its body is massive and muscular, adapted for hunting in a variety of environments, from tropical forests to savannas. The Jaguar possesses one of the most powerful jaws in the animal kingdom, capable of piercing the thick skin of its prey, such as capybaras, deer, and even reptiles like caimans. It is also capable of swimming and often hunts aquatic animals. This feline primarily inhabits Central and South America, from southern Mexico to Argentina, preferring tropical forests, swamps, and riparian zones. While the species is still relatively widespread, it is threatened by deforestation, illegal hunting, and habitat loss.

The jaguarundi is a slender wild cat of 50–60 cm (excluding tail), with short legs and uniform grey or reddish coat. A secretive, diurnal species, it inhabits tropical and deciduous forests, scrub and riparian thickets, preying on ground-feeding birds, small rodents and reptiles.

The Puma yagouaroundi, commonly known as the jaguarundi, is a medium-sized feline native to the Americas. It is characterized by its elongated body, short legs, and long tail. Its coat is uniform, ranging from gray to reddish-brown, allowing it to blend into its surroundings. This feline is primarily solitary and territorial, marking its territory with glandular secretions. It is an opportunistic hunter, feeding on small mammals, birds, and reptiles. Although mainly terrestrial, it is also a good climber and swimmer. Its adaptability to various habitats, from tropical forests to savannas, makes it a resilient predator.

The Japanese Paradise Flycatcher, or Terpsiphone atrocaudata, is an elegant and fascinating bird primarily found in the dense forests of Japan, Korea, and China. This bird is renowned for its glossy black plumage and long tail feathers that can reach up to 30 cm in males. Females, on the other hand, display more subdued colors, with brownish hues and a shorter tail. The Japanese Paradise Flycatcher is a migratory bird, moving south for the winter.

Native to East Asia, it is commonly found in gardens, forests, and urban areas. This bird is highly social and often moves in flocks. It primarily feeds on nectar, fruits, and insects. Its adaptability to various environments makes it a resilient species. Although mainly resident, some individuals migrate seasonally. Its presence is often marked by its melodious song and high-pitched calls.

The Javan Pangolin, also known as the Malayan Pangolin, is a mammal species native to Southeast Asia. It is easily recognized by its body covered with large keratin scales, which protect it from predators. This nocturnal and solitary animal primarily feeds on ants and termites, which it captures with its long, sticky tongue. The Javan Pangolin is an endangered species, mainly due to habitat loss and poaching for its scales and meat. This pangolin is an excellent burrower, digging dens and hides for protection.

The Javan Rhinoceros is a rare and critically endangered species of rhinoceros found primarily on the island of Java in Indonesia. It measures about 3 to 3.5 meters in length, with a tail of 60 to 80 cm, and weighs between 900 and 1,400 kg.
