COVER Development of the light organ of the Hawaiian bobtail squid Euprymna scolopes is triggered by its luminescent bacterial partner Vibrio fischeri shortly after the symbiont colonizes epithelium-lined crypts deep within the organ. In this confocal micrograph, hemocytes can be seen infiltrating the host tissue that will undergo morphogenesis. See page 1186. [Image: T. Koropatnick]
