The exhibit on "River Crabs" features Chinese mitten crabs (Eriochier sinensis) as well as the smaller mitten crabs of Taiwan's rivers. It is with good reason that Chinese mitten crabs, which grow fat on fish and shrimps trapped by sluice gates along the middle to lower reaches of the Yangtze River, have enjoyed an exalted status in Chinese cuisine for over 1,000 years.
在展示「河蟹」的專櫃中，大閘蟹與台灣溪流裡的小毛蟹並列，大閘蟹原是毛蟹的一種，在長江中下游撿食卡在水閘的現成魚蝦，吃得肥胖多滋，中國人千年來對牠情有獨鍾不是沒道理的。
