Approximately 40% of the mitochondria in the sphincter muscle of the crayfish vas deferens have prismatic-type cristae. In cross section, the angular cristae have either triangular or rhomboid profiles which are surrounded by a hexagonal array of electron-dense dots. In longitudinal section, these mitochondria exhibit both thick and thin parallel lines, which represent cristae and filaments, respectively. It is postulated that the matrix of the prismatic-type mitochondria is packed with rodlets composed of an electron-dense core and a less dense shell. Close packing of these rodlets results in the regular hexagonal dot array. Deletion of fascicles of 3 or 4 rodlets results in spaces with triangular or rectangular cross sections. Lining of these spaces with membranes results in cristae with triangular or rhomboid cross sections.
小龙虾输精管括约肌中约40%的线粒体具有棱柱形嵴。在横截面中，角形嵴具有三角形或菱形轮廓，周围环绕着六边形排列的电子致密点。在纵截面中，这些线粒体呈现出粗线和细线，分别代表嵴和细丝。据推测，棱柱形线粒体的基质中充满了由电子致密核心和密度较小的外壳组成的小杆。这些小杆的紧密排列导致了规则的六边形点阵列。去除3或4个小杆的束会导致具有三角形或矩形横截面的空间。这些空间用膜衬里会导致具有三角形或菱形横截面的嵴。
