Whiskers are also known as vibrissa, from the latin vibrare "to vibrate". Vibrissa are the specialized hairs on mammals and the bristlelike feathers near the mouths of many birds. Their resonant design is symbolic of the energies, good and bad, that are reverberating throughout the natural world. Every living thing is connected and, by birthright, deserves to exist.
There are only about 100 Sumatran rhinos, also called Hairy rhinos, left in existence and only nine of them are cared for in captivity. Of those nine, there is only one that lives outside of Southeast Asia. This special guy is Harapan, affectionately known as Harry and who in 2007, was the third of three calves born at the Cincinnati Zoo over six years.
Even more remarkable are the additional successes of the Cincinnati Zoo’s Center for Conservation & Research of Endangered Wildlife (CREW). In 1984, a captive breeding program began but there was no success until 1997, when CREW scientists began using endocrinology and ultrasonography to learn about the reproductive physiology of Sumatran rhinos. Ultimately, this resulted in the first Sumatran rhino calf bred and born in captivity. Harapan’s older brother Andalas was born on September 13, 2001. In 2004, his sister Suci was born. Unfortunately, Suci passed away in 2014 after a prolonged illness that was aggressively treated by staff and veterinarians for months. Suci had hemochromatosis, which is the same condition to which her mother succumbed. Hemochromatosis is an iron storage disease that is known to be inheritable in humans. It likely is inheritable in rhinos also.
In 2007, the Cincinnati and Los Angeles Zoos (where Andalas was living) agreed to send Andalas to the Sumatran Rhino Sanctuary, a breeding facility in the Way Kambas National Park of Indonesia, to replace an old, infertile bull. In 2012, a healthy son was born to Andalas in Sumatra.
This month, the Cincinnati Zoo announced that Harapan will be moved to Indonesia. He is sexually mature and his opportunity to breed and contribute to his species’ survival exists only at the Sumatran Rhino Sanctuary. There are three possible mates awaiting Harry’s arrival.
Listed as Critically Endangered on The International Union for Conservation of Nature and Natural Resources Red List of Threatened Species, the Sumatran rhino is the smallest and last form of the Two-horned hairy rhinos that have lived on the planet for 20 million years. Between 1985 and 1994, a total of 40 rhinos were captured for captive breeding including the seven and three sent to the United States and United Kingdom, respectively, from areas converted to plantations.
The historic range for Sumatran rhinoceros is from the foothills of the Himalayas in Bhutan and north-eastern India, through southern China (Yunnan), Myanmar, Thailand, Cambodia, Lao PDR, Viet Nam and the Malay Peninsula, and onto the islands of Sumatra and Borneo in Indonesia.
Hairy rhinos live in tropical rainforest and montane moss forest, mainly in hilly areas near water sources. Males are primarily solitary, but can have overlapping territories with females, which are commonly found with their young. Their lifespan is estimated at about 35-40 years, gestation length of approximately 15-16 months, and age at sexual maturity estimated at 6-7 years for females and 10 years for males.
Significant threats to survival of this species include poaching and reduced population viability. Hunting is primarily driven by the demand for Traditional Asian Medicine that erroneously believes that rhino horns and other body parts have medicinal qualities. Centuries of over-hunting has reduced this species to a tiny percentage of its former population and range. As a result, breeding activity is infrequent, successful births are uncommon in many populations, and there is a severe risk of inbreeding. These circumstances necessitate this big move for Harry, who is symbolic of decades of cooperative conservation efforts among many dedicated scientists in multiple zoos.
Harapan is the only Sumatran rhino on view to the public anywhere in the world. Zoo visitors can find him in Wildlife Canyon daily from 9 a.m. – 12:30 p.m., weather permitting, until he leaves for Indonesia, the date for which has not yet been determined.
