Poison Dart Frogs of Central and South America are very colorful. Their color may be yellow, red, white, or blue, while MORE?
Central America (Spanish: América Central or Centroamérica) is the central geographic region of the Americas. It is the southernmost, isthmian portion of the North American continent, which connects with South America on the southeast. When considered part of the unified continental model, it is considered a subcontinent. Central America consists of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Central America is part of the Mesoamerican biodiversity hotspot, which extends from northern Guatemala through central Panama. It is bordered by Mexico to the north, the Caribbean Sea to the east, the North Pacific Ocean to the west, and Colombia to the south-east which is also the most southern point of North America.
Central America is an area of 524,000 square kilometers (202,000 sq mi), or almost 0.1% of the Earth's surface. As of 2009, its population was estimated at 41,739,000. It has a density of 77 people per square kilometer. Dart Frogs
South America is a continent located in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It can also be considered as a subcontinent of the Americas. Toxicology
The Red-backed Poison Frog (Ranitomeya reticulata) is a species of frog in the family Dendrobatidae. It is an arboreal insectivorous species, and is the second-most poisonous species in the genus, after R. variabilis. Like many species of small, poisonous frogs native to South America, it is grouped with the poison dart frogs, and is a moderately toxic species, containing poison capable of causing serious injury to humans, and death in animals such as chickens. R. reticulata is native to Peru and Ecuador.
The red-backed poison frog is a moderately toxic dendrobatid, and is the second-most poisonous of the frogs in the Ranitomeya genus. Its toxins are used as the frog's natural defense mechanisms, making them inedible to many, if not most, of the predators in its natural area. To advertise its poison and further reduce the risk of injury, the red-backed poison frog displays its brilliant warning colors, especially its red-orange back, for which it is named. Like all dendrobatids, it does not manufacture its poison itself, but rather is theorized to take the toxins from the ants, mites, and beetles on which it lives. It absorbs the insects' poisons into its body, which is immune to the poison. The poison is stored in skin glands just beneath the frog's epidermis. The poison seeps through open wounds and orifices, and, it is believed, through the pores. This defense is especially effective against mammalian and avian predators, and, to a lesser extent, reptilian ones. Amazonian ground snakes have a limited resistance to the poison, and occasionally will attack such frogs.
Dendrobates auratus, also known as the green and black poison dart frog or the green and black poison arrow frog, and sometimes mint poison frog (not to be confused with the mint-green color morph of Phyllobates terribilis), is a brightly colored member of the order Anura native to Central America and northwestern parts of South America. It is one of the most variable of all poison dart frogs next to Dendrobates tinctorius and some Oophaga spp. It is considered to be of least concern from a conservation standpoint by the International Union for Conservation of Nature (IUCN).
Poison dart frog (also dart-poison frog, poison frog or formerly poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to Central and South America. These species are diurnal and often have brightly colored bodies. Although all wild dendrobatids are at least somewhat toxic, levels of toxicity vary considerably from one species to the next and from one population to another. Many species are threatened. These amphibians are often called "dart frogs" due to the Amerindians' indigenous use of their toxic secretions to poison the tips of blowdarts. However, of over 175 species, only four have been documented as being used for this purpose (curare plants are more commonly used), all of which come from the Phyllobates genus, which is characterized by the relatively large size and high levels of toxicity of its members.
