their reproductive years. The last captive birth for these species in North America was in 2001 in San Diego. Pygmy slow lorises are doing better in North American zoos; from the late 1980s (when they were imported) to 2008, the population grew to 74 animals, with most of them born at the San Diego Zoo. Wildlife trade Until the 1960s, the hunting of slow lorises was sustainable, but due to growing demand, decreased supply, and the subsequent increased value of the marketed wildlife, slow lorises have been overexploited and are in decline. With the use of modern technology, such as battery-powered searchlights, slow lorises have become easier to hunt because of their eyeshine. Traditional medicine made from loris parts is thought to cure many diseases, and the demand for this medicine from wealthy urban areas has replaced the subsistence hunting traditionally performed in poor rural areas. A survey by primatologist Anna Nekaris and colleagues (2010) showed that these belief systems were so strong that the majority of respondents expressed reluctance to consider alternatives to loris-based medicines. Slow lorises are sold locally at street markets but are also sold internationally over the Internet and in pet stores. They are especially popular or trendy in Japan, particularly among women. The reasons for their popularity, according to the Japan Wildlife Conservation Society, are that "they're easy to keep, they don't cry, they're small, and just very cute." Common misconceptions Because of their "cuteness", videos of pet slow lorises are some of the most frequently watched animal-related viral videos on YouTube. By March 2011, a newly posted video of a slow loris holding a cocktail umbrella had been viewed more than two million times, while an older video of a slow loris being tickled had been viewed more than six million times. According to Nekaris, these videos are misunderstood by most people who watch them, since most do not realize that it is illegal in most countries to own them as pets and that the slow lorises in the videos are only docile because that is their passive defensive reaction to threatening situations. Despite frequent advertisements by pet shops in Japan, the World Conservation Monitoring Centre reported that only a few dozen slow lorises were legally imported in 2006, suggesting frequent smuggling. Slow lorises are also smuggled to China, Taiwan, Europe, Russia, the United States, and Saudi Arabia for use as pets. Within their
