Lesser One-horned Rhinoceros

Common Name: Lesser One-horned Rhinoceros
Scientific Name: Rhinoceros sondaicus

Habitat

The Lesser One-horned Rhinoceros primarily inhabits the grasslands and tropical forests of Southeast Asia, particularly found in regions of India, Nepal, Thailand, and Indonesia. These rhinoceroses prefer wetlands and areas close to rivers, where dense vegetation provides shelter and food sources, making these environments critical to their survival.

Physical Characteristics

This magnificent species stands approximately 1.5 to 2 meters tall at the shoulder and can weigh between 900 to 2,300 kg. It is characterized by a single prominent horn, which can reach up to 25 cm in length. The skin is grayish-brown and is distinguished by its thick folds, which provide protection against predators. Notably, the Lesser One-horned Rhinoceros has a unique appearance, with a smaller, more compact body compared to its larger relatives.

Behavior

Lesser One-horned Rhinoceroses are generally solitary animals but can be seen in small groups, especially during mating season. They are known for their elusive nature, primarily being most active during the early morning and late afternoon. These animals communicate through various vocalizations and display marking behaviors to establish territory.

Diet

This herbivorous species primarily feeds on grasses, leaves, and aquatic plants. The Lesser One-horned Rhinoceros has adapted its feeding habits to exploit both terrestrial and aquatic vegetation, often seen munching on tender shoots and foliage in their wetland habitats. Their diet plays a crucial role in maintaining the health of their ecosystem.

Reproduction

The breeding season for the Lesser One-horned Rhinoceros typically occurs during the monsoon months, which provide abundant food resources. After a gestation period of about 15 to 16 months, females give birth to a single calf. Maternal care is significant, with mothers often protective of their young, allowing calves to stay close until they are capable of independent survival.

Conservation Status

The Lesser One-horned Rhinoceros is classified as vulnerable by the IUCN Red List. Threats to its survival include habitat loss due to human encroachment, poaching for their horns, and decreased genetic diversity. Conservation efforts are ongoing to protect remaining populations and their habitats.
