Bali Tiger
Scientific classification

The Bali tiger (Panthera tigris balica) is an extinct tiger population that lived in the Indonesian island of Bali.

Results of mtDNA analysis of 23 tiger samples from museum collections indicate that tigers colonized the Sunda Islands throughout the last glacial period 110,000–12,000 years ago. In Bali, the last individuals were recorded in the late 1930s, although a few animals likely survived into the 1940s and possibly 1950s. The population was extirpated because of habitat conversion and hunting.

Balinese names for the Bali tiger are harimau Bali and samong.

Taxonomic history[]

In 1912, the German zoologist Ernst Schwarz described a skin and a skull of an adult female tiger in the Senckenberg Museum collection, that had originated in Bali. He named it Felis tigris balica and argued that it is distinct from the Javan tiger by its brighter fur colour and smaller skull with narrower zygomatic arches. In 1969, the distinctiveness of the Bali tiger was questioned, since morphological analysis of several tiger skulls from Bali revealed that size variation is similar to Javan tiger skulls. Hue and striping pattern of fur neither differs significantly. A comparison of mitochondrial DNA sequences from 23 museum specimens of Bali and Javan tigers with other living tiger subspecies revealed a close genetic resemblance of the tigers in the Sunda Islands. They form a monophyletic group distinct and equidistant from tigers in mainland Asia.

In 2017, the Cat Classification Task Force of the Cat Specialist Group revised felid taxonomy, and now recognizes the extinct Bali and Javan tiger populations, as well as the Sumatran tiger population as P. t. sondaica.

Characteristics[]

The Bali tiger was described as the smallest tiger in the Sunda islands. In the 20th century, only seven skins and skulls of tigers from Bali were known to be preserved in museum collections. The common feature of these skulls is the narrow occipital plane, which is analogous with the shape of tiger skulls from Java. Skins of males measured between the pegs are 220 to 230 cm (87 to 91 in) long from head to end of tail; those of females 190 to 210 cm (75 to 83 in). The weight of males ranged from 90 to 100 kg (200 to 220 lb), and of females from 65 to 80 kg (143 to 176 lb).

Habitat and ecology[]

Most of the known Bali tiger zoological specimens originated in western Bali, where mangrove forests, dunes and savannah vegetation existed. The main prey of the Bali tiger was likely the Javan rusa (Rusa timorensis).

Extinction[]

At the end of the 19th century, palm plantations and irrigated rice fields were established foremost on Bali's rich volcanic northern slopes and the alluvial strip around the island. Tiger hunting started after the Dutch gained control over Bali. During the Dutch colonial period, hunting trips were conducted by European sportsmen coming from Java, who had a romantic but disastrous Victorian hunting mentality and were equipped with high-powered rifles. The preferred method of hunting tigers was to catch them with a large, heavy steel foot trap hidden under bait, a goat or a muntjac, and then shoot them at close range. Surabayan gunmaker E. Munaut is confirmed to have killed over 20 tigers in only a few years. In 1941, the first game reserve, today's West Bali National Park, was established in western Bali, but too late to save Bali's tiger population from extinction. It was probably eliminated by the end of World War II. A few tigers may have survived until the 1950s, but no specimen reached museum collections after the war.

A few tiger skulls, skins and bones are preserved in museums. The British Museum in London has the largest collection, with two skins and three skulls; others include the Senckenberg Museum in Frankfurt, the State Museum of Natural History Stuttgart, the Naturalis museum in Leiden and the Zoological Museum of Bogor, Indonesia, which owns the remnants of the last known Bali tiger. In 1997, a skull emerged in the old collection of the Hungarian Natural History Museum and was scientifically studied and properly documented.

Cultural significance[]

The tiger had a well-defined position in Balinese folkloric beliefs and magic. It is mentioned in folk tales and depicted in traditional arts, as in the Kamasan paintings of the Klungkung kingdom. The Balinese considered the ground powder of tiger whiskers to be a potent and undetectable poison for one's foe. A Balinese baby was given a protective amulet necklace with black coral and "a tiger's tooth or a piece of tiger bone". The traditional Balinese Barong dance preserves a figure with the mask of a tiger called Barong Macan.

Balinese people are fond of wearing tiger parts as jewelry for status or spiritual reasons, such as power and protection. Necklaces of teeth and claws or male rings cabochoned with polished tiger tooth ivory still exist in everyday use. Since the tiger has disappeared on both Bali and neighboring Java, old parts have been recycled, or leopard and sun bear body parts have been used instead.[citation needed]
