Delaware designated the grey fox (Urocyon cinereoargenteus) as the official state wildlife animal in 2010. Indigenous to Delaware,it is estimated that this unique animal has existed between 7 and 10 million years. The grey fox is the only member of the canid family (canines) which is able to climb trees (the gray fox can also run up to 28 miles per hour! ).
The fourth grade students at Joseph M. McVey Elementary School suggested that the grey fox be designated as Delaware's official state wildlife animal (part of teacher Paul Sedacca's lessons on persuasive writing).
