Gastrotheca
''Gastrotheca'' is a genus of frogs in the family (biology), family Hemiphractidae. They are found in Central America south of Costa Rica and in South America. Most species occur in the American Cordillera from southern Costa Rica to north-western Argentina. This genus makes up the bulk of Amphignathodontidae, marsupial frog diversity; formerly it was placed in the "Leptodactylidae" assemblage. Marsupial frogs are so-called because they possess a dorsal brood pouch. In some species the eggs are fertilized on the female's lower back, and are inserted in her pouch with the aid of the male's toes. The eggs remain in contact with the female's circulatory system, vascular tissue, which provides them oxygen. ''Gastrotheca guentheri'' (Guenther's marsupial frog) is the only known frog with true teeth in its lower jaw. ''Gastrotheca riobambae'' (Andean marsupial tree frog) is kept as pet and is used in scientific experiments. ''Gastrotheca gemma'' was additionally discovered in 2021. ...

Gastrotheca Argenteovirens
''Gastrotheca argenteovirens'' is a species of frog in the family Hemiphractidae.

Gastrotheca Guentheri
''Gastrotheca guentheri'' (common names: Guenther's marsupial frog, dentate marsupial frog) is a species of frog in the family Hemiphractidae. It is found in the Andes of Colombia ( Cordillera Occidental and Colombian Massif) and Ecuador ( Cordillera Occidental). ''Gastrotheca guentheri'' is the only known frog with true teeth in both of its jaws, as indicated by the name of the genus it originally typified, ''Amphignathodon'', described by George Albert Boulenger in 1882. Description ''Gastrotheca guentheri'' is the only known frog with true teeth in its lower jaw. Its teeth have re-evolved after being absent for over 200 million years, challenging Dollo's law. Re-evolution of teeth in the lower jaw may have been made easier because the frogs have teeth in their upper jaw so there was already a biochemical pathway for developing teeth after 200 million years, unlike, say, birds. Biochemically, this may be an example of a suppressor of a regulatory gene disappearing. Males meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastrotheca Riobambae
The Andean marsupial tree frog (''Gastrotheca riobambae''), also known as the Riobamba marsupial frog or Riobamba pouched frog, is a species of frog in the family Hemiphractidae. It is endemic to Ecuador. The species is confined to the Andes and the inter-Andean valleys, from Imbabura south to Chimborazo. They live in an altitude of 2,200-3,500 meters above sea-level. The Andean marsupial tree frog's habitat varies from the montane forests to the dry rocky hillsides, and from the agave plants to the corn fields. Once a common species, it is threatened by severe habitat loss. Snout–vent length of ''Gastrotheca riobambae'' is about . It has a broad, depressed body. Skin is smooth above but granulated below.
