The White-bellied Sea Eagle is a large bird of prey found along coastlines, rivers, lakes, and wetlands across Asia, Australia, and the Pacific. It is recognized by its white head, chest, and belly, contrasting with dark gray wings and back. Feeding mainly on fish, waterbirds, and other small animals, it is a powerful hunter and scavenger. As a top predator, it plays an important role in maintaining healthy aquatic ecosystems.

The Bornean Keeled Pit Viper is a venomous snake found in the tropical rainforests of the island of Borneo. It is recognized by its rough, keeled scales and excellent camouflage, allowing it to blend into forest vegetation. An ambush predator, it feeds on small mammals, birds, frogs, and lizards, using heat-sensing pits to detect prey. Like many rainforest species, it depends on healthy forest habitats for its survival.

The Proboscis Monkey is a unique primate found only on the island of Borneo. Males are famous for their large, pendulous noses, while both sexes are excellent swimmers with partially webbed feet. Proboscis Monkeys live in mangrove forests, riverbanks, and coastal swamps, feeding mainly on leaves, fruits, and seeds. Habitat loss has made this remarkable species endangered.

The Bornean Sun Bear is the smallest bear species and is found in the tropical rainforests of Borneo. It is recognized by its short black fur, long tongue, and the pale crescent-shaped patch on its chest. Feeding on insects, honey, fruit, and small animals, it plays an important role in seed dispersal and forest health. Habitat loss and illegal wildlife trade have made this unique bear increasingly vulnerable.

The Bornean Slow Loris is a small, nocturnal primate found in the rainforests of Borneo. It is recognized by its large eyes, slow movements, and strong grasping hands and feet. Feeding on insects, tree sap, fruit, and nectar, it is one of the few venomous mammals, using a toxin produced near its elbows as a defense. Habitat loss and the illegal pet trade have made this unique primate vulnerable.

The Rhinoceros Hornbill is a large, colorful bird found in the tropical rainforests of Southeast Asia, especially on the island of Borneo. It is recognized by its enormous yellow and orange casque that curves upward from its bill. Feeding mainly on fruit, along with insects and small animals, it plays a vital role in dispersing seeds throughout the forest. Habitat loss and hunting have caused declines in many wild populations.
