The gills of Penaeus aztecus were examined by light and electron microscopy. They are dendrobranchiate, consisting of a central axis with biserially arranged branches that subdivide into bifurcating filaments. A septum divides the lumina of these structures into afferent and efferent channels. Hemolymph from the sternal sinus flows through the afferent channels into the filaments where it is directed into the efferent channels and finally to the pericardial cavity. In addition to these channels, numerous blood vessels permeate the gill. The cuticle covering the gill overlies a thin epithelium which is separated from hemolymph by a basal lamina. The epithelium, which is active in cuticle secretion, has a series of pillar processes that form subcuticular lacunae. The apical membranes of epithelial cells become folded in shrimp exposed to hypo- and hyperosmotic salinities. Granular cells that contain elaborate Golgi apparati and several types of granules are present throughout the gill. Nephrocytes resembling glomerular podocytes line the efferent channels. A large nerve traverses the septum in the axis.
对墨西哥对虾的鳃进行了光学显微镜和电子显微镜检查。它们是枝状鳃，由一个中心轴和双列排列的分支组成，这些分支再细分为二叉状的细丝。一个隔膜将这些结构的管腔分为入流通道和出流通道。来自胸骨窦的血淋巴通过入流通道流入细丝，在细丝中它被导向出流通道，最后进入心包腔。除了这些通道外，许多血管贯穿鳃。覆盖鳃的角质层覆盖着一层薄上皮，上皮通过基膜与血淋巴隔开。活跃于角质层分泌的上皮有一系列柱状突起，形成皮下腔隙。在暴露于低渗和高渗盐度的虾中，上皮细胞的顶端膜会折叠。鳃中各处都存在含有精细高尔基体和几种类型颗粒的颗粒细胞。类似肾小球足细胞的肾细胞排列在出流通道内。一条大神经穿过轴中的隔膜。
