CUVIERīS WEEPING FROG Physalaemus cuvieri
A common Paraguayan Physalaemus that does not give the "racing car" song typical of many other Paraguayan members of the genus. Males give a throaty croak whilst floating in shallow water, tilting backwards and forwards as they pound out their rhythm! They are burrowing frogs and possess a tubercle on the foot which acts as a sort of "spade". This small species is most easily recognised by its red "groin" and spotted belly, but is otherwise extremely similar to the Pale-legged Weeping Frog .

Gallery 2: Colour variation in adult Physalaemus cuvieri
Like many Anurans skin colouration of this species is highly variable. Above are some examples of photochromatism found in this species. Specimens from 2e onwards are from Laguna Blanca and form part of the Para La Tierra scientific collection.
