Xenohyla Truncata
''Xenohyla truncata'', the Izecksohn's Brazilian treefrog, is a species of frugivorous tree frog in the family Hylidae. It is endemic to the State of Rio de Janeiro, Brazil. The range of this frog ranges from the southern border of Espírito Santo down to Ilha da Marambaia, inhabiting mostly restingas near the coast and on some islands. They shelter inside bromeliads such as '' Neoregelia cruenta'' during the day and breed in temporary pools. When disturbed, this tree frog will tilt its head down, outstretch its legs, and puff up. This posture breaks up the frogs outline and makes it appear larger. These tree frogs are listed as near threatened because they are restricted to an area of less than 20,000 square kilometres and because human development modifies or destroys their restinga habitats. As a juvenile, ''Xenohyla truncata'' has white stripes down the sides of its body but they disappear at maturity, leaving the adult frog a uniform brown or orange. This species of frog is ...

Amphibians Described In 1959
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic dec ...
