Cover illustration. Neocaridina davidi is a freshwater shrimp that is commonly bred all over the word. It has pelagic larvae that differ considerably in their morphology and habits from adults. In this issue of the Journal of Morphology, Sonakowska‐Czajka and collaborators (pp. 48‐65) document the 3D‐morphology of the midgut of larval stages using X‐ray microtomography, and, using light and transmission electron microscopy, provide a detailed description of structural and ultrastructural changes of the midgut epithelium (intestine and hepatopancreas) that occur during postembryonic development. The cover images shows a zoea III larva of Neocaridina davidi with the long intestine (green) and hepatopancreas (red).

封面插图。Neocaridina davidi是一种淡水虾，通常在世界各地繁殖。它的浮游幼虫在形态和习性上与成虫大不相同。在本期《形态学杂志》中，Sonakowska‐Czajka及其合作者（第48‐65页）使用X射线显微断层摄影术对幼虫中肠的3D形态进行了记录，并利用光和透射电子显微镜提供了详细的信息。描述胚胎后发育过程中中肠上皮（肠和肝胰腺）的结构和超微结构变化。封面图片显示了达卡第新虫的zoea III幼虫，长肠（绿色）和肝胰腺（红色）。
