how many types of poison dart frogs are there
about 170 species
title: Poison dart frog text: this from their diet of ants, mites and termites. Other species however, that exhibit cryptic coloration and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened due to human infrastructure encroaching the places they inhabit. These amphibians are often called "dart frogs" due to the Amerindians' indigenous use of their to poison the tips of blowdarts. However, of over 170 species, only four have been documented as being used for this purpose (curare plants are more commonly used), all of which come from the genus "Phyllobates", which is characterized title: Poison dart frog text: Poison dart frog Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive title: Poison dart frog text: by the relatively large size and high levels of toxicity of its members. Most species of poison dart frogs are small, sometimes less than in adult length, although a few grow up to in length. They weigh 1 oz. on average. Most poison dart frogs are brightly colored, displaying aposematic patterns to warn potential predators. Their bright coloration is associated with their toxicity and levels of alkaloids. For example, frogs of the genus "Dendrobates" have high levels of alkaloids, whereas "Colostethus" species are cryptically colored and are not toxic. Poison dart frogs are an example of an aposematic organism. Their title: Poison dart frog text: as 25 years. These claims also seem to be questionable, since many of the larger species take a year or more to mature, and "Phyllobates" species can take more than two years. In captivity, most species thrive where the humidity is kept constant at 80 to 100% and where the temperature is around to during the day and no lower than to at night. Some species tolerate lower temperatures better than others. Many species of poison dart frogs have recently experienced habitat loss, chytrid diseases, and collection for the pet trade. Some are listed as threatened or endangered as a title: Poison dart frog text: the throat of bromeliads or other plants. The tadpoles remain there until they metamorphose, fed by unfertilized eggs laid at regular intervals by the mother. Poison dart frogs are endemic to humid, tropical environments of Central and South America. These frogs are generally found in tropical rainforests, including in Bolivia, Costa Rica, Brazil, Colombia, Ecuador, Venezuela, Suriname, French Guiana, Peru, Panama, Guyana, Nicaragua, and Hawaii (introduced). Natural habitats include subtropical and tropical, moist, lowland forests, subtropical or tropical high-altitude shrubland, subtropical or tropical, moist, montanes and rivers, freshwater marshes, intermittent freshwater marshes, lakes and swamps.
