 The tadpoles are detritivores, either scavengers or herbivores depending on morph

Tadpole "nests" can bee seen in most xeric amphibians, and are well described in the fossil record, such as at the St. George Dinosaur Discovery site.The shallow depressions are a form of "vortex feeding" used to stir up debris for feeding.It is also theorized that the depressions formed could allow a lengthened hydroperiod to increase growth size.
