Fig. 2.1. Morphology of dicyemids. a, Dicyemid embryos (em) develop inside the central axial cell (a, white line), which is covered by a single layer of ciliated epidermal cells. Stained nuclei, plasma membrane, and cilia, showing the simple morphology of a sexually reproductive adult Dicyema japonicum with no coelom, gut, or other organs. Sperm cells and eggs produced by hermaphroditic gonads (g) fertilize, and embryos develop inside the central axial cell. Anterior is to the left. b, The central axial cell is covered with a single layer of ciliated epidermal cells (ep). c, Developing larvae produced sexually, possess long cilia for motility to reach a new host. Fluorescence: yellow, plasma membrane labeled with CellMask Deep Red; blue, nuclei labeled with DAPI; red, acetylated tubulin. Scale bar, 20 μm
