Bromeliad ostracods pass through amphibian (Scinaxax perpusillus) and mammalian guts alive

During a study about bromeliad tadpoles (Scinax perpusillus), the ability of bromeliad ostracods (genus Elpidium) to pass unharmed through the tadpole gut was documented. Seven Elpidium were found alive inside a tadpole's digestive tract. Subsequent experiments demonstrated that Scinax tadpoles frequently ingest bromeliad ostracods, eliminating them unharmed in the faeces. Another laboratory experiment demonstrated these ostracods' ability to pass through a mammalian (mouse) gut alive. The consequences of this ability in ostracod ecology and evolution is discussed. Biotic and abiotic data from the bromeliads where the ostracods and tadpoles were collected are given.
