QPQ not necessary, article recently promoted to GA within time-frame. Images rights appear to be in order. Earwig and spot checks reveal nothing exciting.
- The orginal citation states,
generally include a proteinaceous matrix in which mineral elements are embedded, either self-secreted (Euglypha, Quadrulella, Lesquereusia), taken from the surrounding environment (Centropyxis, Difflugia) or from prey organisms (Nebela, Padaungiella, Apodera).
- The page states,
Kleptosquamy, the ability of hyalosphenid amoebae to "steal" test scales from their prey, euglyphid amoebae, is hypothesized to be an ancestral trait within the family.
- However, the source 'The Phanerozoic diversification of silica-cycling testate amoebae and its possible links to changes in terrestrial ecosystems' states:
Hyalosphenids, a group within arcellinids, are predators of euglyphids. We demonstrate that hyalosphenids can construct shells using silica scales mineralized by the euglyphids. Parsimony analyses of the current hyalosphenid phylogeny indicate that the ability to “steal” euglyphid scales is most likely ancestral in hyalosphenids
, which is more direct to the DYK claim.
