In Ernst Haeckel's classic book Kunstsformen der Natur (Art Forms in Nature), forams are prominent; they occupy three of the 100 plates. In one plate, the centerpiece is Peneroplis planatus shown with extended rhizopods, and organisms from the plankton. It is a very curious illustration as it is the only foram shown living, and one of only two orga...
