Chile and Argentina (Crump 1999).
is found in temperate forests and rainforests (Cannatella 1995, Gallardo 1999).
has a triangular shaped head with a long, and somewhat pointy nasal extension. Color ranges from brown to bright green depending on the substrate is imitating. The ventrum is more brilliantly colored with a black background and big white spots as well as smaller yellow and orange spots. Its skin is basically smooth with only a few wart glands (Gallardo 1999).
Femalelay their eggs on moist soil and when the eggs hatch, the males "swallow" the tadpoles and put them in their specialized vocal sacs. The tadpoles stay there through metamorphosis, about 6 weeks, and then are released in a series of convulsive movements as miniature frogs (Cogger and Zweifel 1998, Gallardo 1999)
is insectivorous (Gallardo 1999).
is also known as the "Cowboy Frog" locally. Some explanations for this are that they sound like a cowboy whistling for his cattle, the ventrum spots look like cow spots, and they possess skin extensions on their legs that look like spurs.

living in the southern part of the New World. In other words, Central and South America.
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
an animal that mainly eats meat
animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature
fertilization takes place outside the female's body
union of egg and spermatozoan
forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality.
having a body temperature that fluctuates with that of the immediate environment; having no mechanism or a poorly developed mechanism for regulating internal body temperature.
An animal that eats mainly insects or spiders.
A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.
having the capacity to move from one place to another.
the area in which the animal is naturally found, the region in which it is endemic.
reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body.
rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
reproduction that includes combining the genetic contribution of two individuals, a male and a female
that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle).
