The anatomy and cellular composition of the digestive tract of decapod crustaceans is in many aspects considerably different from the vertebrate system. These differences include primarily the gastric mill and a sophisticated filter apparatus in the stomach and the hepatopancreatic tubule system with its bi-directional movement of fluids. Further differences are the lack of a strongly acidic pH and pepsin in the stomach. Consequently, many of the physiological processes are fundamentally different as well, particularly the physical and chemical processing of the feed and the synthesis, storage and mode of action of the digestive enzymes. The hepatopancreas is a central organ of metabolism and includes functions which, in vertebrates, are confined to intestine, liver and pancreas.
十足目甲壳动物消化道的解剖结构和细胞组成在许多方面与脊椎动物系统有很大不同。这些差异主要包括胃磨和胃内复杂的过滤装置，以及具有双向液体流动的肝胰管系统。其他差异还包括胃中缺乏强酸性pH值和胃蛋白酶。因此，许多生理过程也存在根本差异，尤其是饲料的物理和化学处理以及消化酶的合成、储存和作用方式。肝胰腺是代谢的中心器官，其功能在脊椎动物中分别局限于肠道、肝脏和胰腺。
