This photo is in honor of Squirrel Appreciation Day (actually on January 21st). Some fun squirrel facts:

• There are more than 300 species of squirrel.
• Different types of squirrels range in size from five inches (the African pygmy squirrel) to three feet (Indian giant squirrel).
• The word “squirrel” comes from the Greek word skiouros, which means shadow-tailed.
• Squirrels have brought down the NASDAQ stock market twice, once in 1987 and once in 1994.
