Pseudis paradoxa, known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America. Its name refers to the very large—up to 27 cm (11 in) long—tadpole, which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length. Although the recordholder was a tadpole in Amapá that belonged to this species, others in the genus Pseudis also have large tadpoles and ordinary-sized adults.
Rhinella rubropunctata is a species of toad in the family Bufonidae that is found in southern Chile and Argentina. Its natural habitats are humid to xeric temperate forests and open environments. It tolerates a certain degree of disturbance. Breeding takes place in shallow temporary ponds near rivers, reservoirs and lakes. It is threatened by habitat degradation and fragmentation.
Nymphargus grandisonae is a species of frog in the family Centrolenidae. It is found in Andes of Colombia and Ecuador. Its natural habitat is tropical moist montane forest ; larvae develop in streams and still-water pools. Its habitat is threatened by habitat loss, introduced fish, and agricultural pollution, but it is still a common species not considered threatened by the IUCN.

Breeding takes place in water.
Batrachyla fitzroya is a species of frog in the family Batrachylidae. It is endemic to Argentina and only known from its type locality, Isla Grande in Lake Menéndez, in the Los Alerces National Park, Chubut Province. The specific name fitzroya refers to Fitzroya cupressoides, a prominent tree at the type locality.
Batrachyla nibaldoi is a species of frog in the family Batrachylidae. It is endemic to Chile and known from the Los Lagos and Aysén Regions between Villa O'Higgins in the south and Kent and Melchor Islands in the north; there is a record from Alao Island further north but this might represent Batrachyla taeniata. The specific name nibaldoi honors Nibaldo Bahamonde, Chilean marine biologist, in recognition of his "remarkable contribution to the development of the zoology in Chile". Common name Nibaldo's wood frog has been coined for it.

Hylorina sylvatica is a species of frog in the family Batrachylidae. It is monotypic within the genus Hylorina. It is found in Argentina and Chile. This species is endemic to the austral Nothofagus forests of Chile and Argentina with a narrow distribution along the eastern slopes of the Andes.
