Zoologists debate about whether pandas are bears or raccoons as they share traits from both species. The jaw and cheek muscles on a giant panda are so powerful they can chew up an aluminum can into small pieces. They can also bite through bamboo stalks so thick that humans have a hard time cutting them with an ax. Female pandas only ovulate once each year, and during that ovulation period, they are only fertile for two or three days. These three-dimensional resin charms are hand-painted.
