Crowds of crocodiles surface on the water at a park in Nanjing, capital of East 皇冠体育app's Jiangsu province, Sept 8, 2012. The picture of the phenomenon was posted online, leading many to assume that an earthquake may be looming. However, according to the park, the creatures are cold blooded animals and fond of sunshine, which has driven them to emerge from the water. The Nanjing Earthquake Bureau also said the area is not prone to earthquakes based on the latest surveillance data. [Photo/CFP]
