A specimen in the Census of Marine Zooplankton – (CC BY-NC-SA). A set of tests run on some juvenile animals of inflexa has revealed the danger, for this species and, by extension, for the whole genus, family and maybe order, of ocean acidification: maldevelopments of the shell, or complete absence in low pH environments (Comeau & al., 2010).
