There's still hope for dolphins

It's a special sight off the island of Lung Kwu Chau, near Tuen Mun. Dozens of bubble-gum pink dolphins and grey youngsters were merrily riding waves and chasing fish. The weather was dreary, but the Chinese white dolphins were having the time of their lives.

Cherished by locals and tourists, the fun-loving dolphin has long been seen as a symbol of Hong Kong. Despite its name, the species is grey when it is young, and pink as an adult.
