Northern New South Wales has its own mystery animal stalking the streets and bush land. Many local people have seen it. When talking to friends they are often surprised to find that they too have seen it. It looks like someone has crossed a dog with a kangaroo. It is observed at night as locals drive their cars through the wildlife corridors that surround our homes. Fishing parties on Marshalls Creek have seen it, as have people relaxing on their verandas. Families pedalling their bicycles during the day have seen it. At first, they believe that the animal is a dog or fox. Closer observations reveal unexpected characteristics.
Cryptic species - animals that appear identical but are genetically quite distinct - may be much more widespread than previously thought. The findings could have major implications in areas ranging from biodiversity estimates and wildlife management to our understanding of infectious diseases and evolution. Reports of cryptic species have increased dramatically over the past two decades with the advent of relatively inexpensive DNA sequencing technology.
