Babirusa

life science Maturity 5-7 Next article →

The babirusa is a unique genus of animals within the swine family. They are often called "deer-pigs" because of their unusual appearance. These animals belong to the genus Babyrousa. They are found on several Indonesian islands, including Sulawesi, Togian, Sula, and Buru.

For a long time, scientists believed all babirusas were a single species named B. babyrussa. However, in 2002, researchers split them into several distinct species. This change was based on the phylogenetic species concept. Scientists looked at differences in body size, hair amount, and skull measurements to make this decision.

The most striking feature of the male babirusa is its canine teeth. These teeth function as large, curving tusks. The upper canines emerge vertically from the alveolar process, which is the bone that holds the teeth. These tusks pierce through the skin of the snout. They then curve backward over the face toward the forehead.

The lower canines also grow upward. The way these tusks look depends on the specific species. For example, the golden babirusa has short, slender upper canines. In the North Sulawesi babirusa, the upper canines are long and thick. These tusks are used for different purposes during fights. The upper tusks are used for defense, while the lower tusks act as offensive weapons.

If a male does not regularly grind his tusks, they can grow so long that they penetrate his own skull.

Different species of babirusa have very different physical traits. The golden babirusa, or Buru babirusa, has long, thick hair. This hair can be white, creamy gold, black, or gold. The Togian babirusa also has long hair, but it is not as thick as the golden variety. Its hair color can be tawny, brown, or black.

In contrast, the North Sulawesi babirusa has very short hair and often appears bald. Females differ from males in several ways as well. Most females have either very small or no tusks at all. They also have only one pair of teats. These physical differences help scientists categorize the different types of babirusas found across the islands.

Babirusas have a specific way of living in the wild. They prefer the habitat of tropical rainforests, especially near river banks. While they once lived in lowland areas near coasts, they now seem to stay in higher interior grounds. They are active during the daytime. As omnivores, they eat a wide variety of foods. This includes leaves, roots, fruits, and animal material.

Their strong jaws allow them to crack open very hard nuts. Interestingly, they do not dig with their snouts like many other pigs. This is because they lack a rostral bone in their nose. They only use their snouts to dig in mud or swampy areas. Their digestive system is similar to a domestic pig, though they have an enlarged stomach diverticulum. This feature led some to wonder if they were ruminants, but evidence shows they are not.

Human history is closely tied to the babirusa. Very old cave paintings on the island of Sulawesi date back at least 35,400 years. These prehistoric paintings show that babirusas were important to people during the Pleistocene epoch. In Indonesia, the animal's strange look has inspired art. For instance, the ceilings of old palaces like the Klungkung palace feature painted babirusa raksasa, or grotesques.

There is even a religious debate regarding the animal. Some Jewish scholars discuss whether the babirusa is kosher. This debate focuses on whether the animal chews its cud. While some experts argue the animal does not truly ruminate, others point to its cloven hoof. Because they are endangered, most Muslims also avoid the meat due to uncertain religious status.

The social structure of babirusas varies by sex. Males tend to live a solitary life. They rarely travel in groups of more than two or three. Adult females, however, often live in groups with their young. These female groups can be quite large, sometimes reaching up to 84 individuals. Most of these groups do not contain any adult males. This social separation is a key part of how the species survives in the rainforest.

Today, the babirusa faces serious threats to its survival. All species in the genus are listed as vulnerable or endangered by the IUCN. This means they are at high risk of extinction. One major threat is poaching, where animals are hunted illegally. Another problem is habitat loss caused by commercial logging. When forests are cut down, the babirusas lose their cover. This makes it much easier for poachers to find them. Protecting the tropical rainforests is essential for the future of these unique animals.
