There are no native species of frog in New York that are known to be poisonous. Poisonous frogs anywhere in North America are extremely rare.
New York is a state in the Northeastern region of the United States. New York is the 27th-most extensive, the third-most populous, and the seventh-most densely populated of the 50 United States. New York is bordered by New Jersey and Pennsylvania to the south and by Connecticut, Massachusetts and Vermont to the east. The state has a maritime border with Rhode Island east of Long Island, as well as an international border with the Canadian provinces of Ontario to the west and north, and Quebec to the north. The state of New York is often referred to as New York State, so as to distinguish it from New York City.
New York City, with a Census-estimated population of over 8.3 million in 2012, is the most populous city in the United States. Alone, it makes up over 40 percent of the population of New York State. It is known for its status as a center for finance and culture and for its status as the largest gateway for immigration to the United States. New York City attracts considerably more foreign visitors than any other US city. Both the state and city were named for the 17th century Duke of York, future King James II of England.
North America is a continent wholly within the Northern Hemisphere and almost wholly within the Western Hemisphere. It is also considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.
North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 4.8% of the planet's surface or about 16.5% of its land area. As of July 2008, its population was estimated at nearly 529 million people across 23 independent states, representing about 7.5% of the human population. Most of the continent's land area is dominated by Canada, the United States, and Mexico, while smaller states exist in the Central American and Caribbean regions. North America is the third-largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe.
Poisonous amphibians are amphibians that produce toxins to defend themselves from predators.
Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, amphibians are not known to actively inject venom, most toxic amphibians are instead known to be poisonous to touch or eat. Amphibians usually sequester toxins from animals and plants that they feed on, commonly from poisonous insects or poisonous plants. One example of this is the well known poison dart frog. They get a deadly chemical called lipophilic alkaloid from consuming a poisonous plant in the rainforest. And they are immune to the poison so they secrete it through their skin as a defense mechanism against predators, just as other amphibians do. This poison is so efficient that the native people of the south American amazons use the frogs toxins on their weapons to kill their prey, giving the frogs their nickname the "poison arrow dart frog". However other people use the Bufotoxins of some species of toxic toads as a drug to get high, but this can become very dangerous. Usually due to the toads' size and toxicity the poisons would not be deadly to a fully grown, healthy adult. But if too much of the toxins are absorbed, or if the person is young or ill then the poisons can become a serious threat. It also depends on the species, because some types of amphibians do have toxins strong enough to kill even a healthy and fully matured person within just a few minutes, while other species may not have toxins potent enough to have any effect on you at all. In addition licking toads is not biologically practical. In order for these tryptamines to be orally activated, the human monoamine oxidase (MAO) system needs to be inhibited. Therefore licking a poisonous amphibian won't guarantee receiving a high sensation.
Poison dart frogs
Lost frogs is a term given to frogs which have been, usually accidentally, outside of their original distribution.
The term mainly applies to Australia, due to the large number of frogs (up to 10,000 a year) transported accidentally while hiding in fruit produce, flowers and building and landscape supplies. Most of the lost frogs each year are moved from Northern Australia to the larger cities in the south.
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.
