剖析殺手 Anatomy of a Praying Mantis

科學圖說 Scientific introduction

去除六足的寬腹螳螂雌蟲消化道解剖圖。昆蟲消化道分為取入食物的前腸、消化食物的中腸和營養吸收代謝的後腸。不同種的昆蟲，其內部構造也有各種變化。肉食性的螳螂會將獵物咬碎並吞入，獵物有時體型大且無法隨時獲得食物，可藉由發達的前腸儲存攝入的大量食物。圖由左而右分別為細長的食道、球狀膨大的嗉囊、不發達的中後腸，腹部末端黃色成對的是卵巢、藍色管狀的生殖副腺和白色球狀的受精囊，周圍則是散落的肌肉及脂肪組織。

This is the digestive system of a female praying mantis (Hierodula patellifera). The alimentary canal  consists of the foregut (food intake), midgut (digestion of food) and hindgut (absorption and metabolism of nutrients) with variations in the internal structures among different species. The carnivorous praying mantis breaks up its prey into pieces before swallowing it. Some of the pieces may be stored in the foregut. From left to right are the long esophagus, inflated sphere-shaped crop, and the undeveloped midgut & hindgut. At the end of the abdomen are yellow ovaries, blue tube-shaped reproductive accessory glands and white spherical spermatheca. These organs are surrounded by muscle and fatty tissue.
