Besides these exhibits, which are common in any kind of aquatic products museum, this museum also gives visitors an opportunity to see some special ones. A Dugong, colloquially called mermaid, about 2 meters (about 6.6 feet) long, is on display in the Sea Animal Hall. The mammal of Dugong is quite rare on earth now. Some sea animals are protected by the Chinese government, such as the Chinese White Dolphin and the cowfish, which are on exhibition in the same hall.
