ALGAE SPACE SHIPS. “Unicellular phytoplanktonic algae make elaborate and beautiful calcite plates called heterococcoliths, which constitute the largest carbonate sink in oceanic biogeochemical cycles and are major sediment formers. E. Huxleyi is one of these that assembles the calcite plates from complex photo-crystals in a highly complex manner, to construct a plate that resembles our images of space ships.”
