Phyllobates Aurotaenia Red
''Phyllobates'' is a genus of poison dart frogs native to Central and South America, from Nicaragua to Colombia. There are 3 different Colombian species of ''Phyllobates'', considered highly toxic species due to the poison they contain in the wild. ''Phyllobates'' contains the most poisonous species of frog, the golden poison frog (''P. terribilis''). They are typical of the poison dart frogs, in that all species have bright warning coloration (aposematism), and have varying degrees of toxicity. Only species of ''Phyllobates'' are used by natives of South American tribes as sources of poison for their hunting darts. The most toxic of the many poisonous alkaloids these frogs contain (in glands in their skin) is batrachotoxin, alongside a wide variety of other toxic compounds. Some populations of '' Phyllobates lugubris'' in Central America are not known to be toxic. Taxonomy ''Phyllobates'' (Ancient Greek for "leaf climber") used to contain many of the species which are now wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Poison Frog
The golden poison frog (''Phyllobates terribilis''), also known as the golden dart frog or golden poison arrow frog, is a poison dart frog endemic to the rainforests of Colombia. The golden poison frog has become endangered due to habitat destruction within its naturally limited range. Despite its small size, this frog is likely the most poisonous animal on the planet. Taxonomy and etymology The golden poison frog was described as ''Phyllobates terribilis'' in 1978 by herpetologists Charles W. Myers and Borys Malkin as well as biochemist John W. Daly; the species name ''terribilis'' is a reference to the deadly toxins present in the skin secretions of this species. Myers' research was based on hundreds of specimens collected on an expedition to the Quebrada Guangui and La Brea regions of the Colombian rainforest, and a breeding colony of 18 frogs established at the American Museum of Natural History.

Phyllobates Vittatus
The Golfodulcean poison frog or Golfodulcean poison-arrow frog (''Phyllobates vittatus'') is a species of frog in the family Dendrobatidae endemic to Costa Rica. Poison Like all members of the genus ''Phyllobates'', Golfodulcean poison frogs have highly potent neurotoxic alkaloid poisons in their skin. While it is only the fourth-most toxic of the genus, the Golfodulcean poison frog is still a highly toxic animal. Its poison causes severe pain, followed by tonic-clonic seizures and paralysis if a large enough dose of the toxin is administered. The frog, for protection, advertises its toxin with its multi-coloured body. Because it is of comparatively large size for a poison dart frog, the Golfodulcean poison frog can store a large amount of poison in its skin. Captive examples lack the toxin, which suggests they do not manufacture the poison themselves, but instead acquire it from a species of insect or other small invertebrate on which they feed.

Pumiliotoxin 251D
Pumiliotoxin 251D is a toxic organic compound. It is found in the skin of poison frogs from the genera ''Dendrobates'', ''Epipedobates'', '' Minyobates'', and ''Phyllobates'' and toads from the genus '' Melanophryniscus''. Its name comes from the pumiliotoxin family (PTXs) and its molecular mass of 251 Daltons. When the toxin enters the bloodstream through cuts in the skin or by ingestion, it can cause hyperactivity, convulsions, cardiac arrest and ultimately death. It is especially toxic to arthropods (e.g. mosquitoes), even at low (naturally occurring) concentrations. Chemical properties Structure The chiral centers in pumiliotoxin 251D can give several stereoisomers of the compound. Only one form of the toxin is present in nature and has toxic properties. Two enantiomers of pumiliotoxin 251D. On the left the plus enantiomer is shown which is toxic. On the right side the minus enantiomer, which is not toxic, is shown.

Allopumiliotoxin 267A
Allopumiliotoxin 267A is a toxin found in the skin of several poison frogs of the family ''Dendrobates''. It is a member of the class of compounds known as allopumiliotoxins. The frogs produce the toxin by modifying the original version, pumiliotoxin 251D. It has been tested on mice and found to be five times more potent than the former version. It has been produced synthetically through a variety of different routes. See also * Pumiliotoxin * Allopumiliotoxin Allopumiliotoxins are a structural division in the pumiliotoxin-A class of alkaloids. The compounds of the pumiliotoxin-A class are primarily found in the skins of frogs, toads, and other amphibians and are used as a chemical defense mechanism to ...

Melyridae
Melyridae (common name: soft-winged flower beetles) are a family of beetles of the superfamily Cleroidea. Description Most are elongate-oval, soft-bodied beetles 10 mm long or less. Many are brightly patterned in black and brown, yellow, or red. Some melyrids ( Malachiinae) have peculiar orange structures along the sides of the abdomen, which may be everted and saclike or withdrawn into the body and inconspicuous. Some melyrids have the two basal antennomeres greatly enlarged. Most adults and larvae are predaceous, but many are common on flowers. The most common North American species belong to the genus ''Collops'' ( Malachiinae); ''C. quadrimaculatus'' is reddish, with two bluish black spots on each elytron. Four New Guinean species of ''Choresine'' (the more abundant '' C. pulchra'', the less abundant '' C. semiopaca'' and the two infrequent '' C. rugiceps'' and '' C. sp. A'', the latter as yet unnamed) have been found to contain batrachotoxins, which may account f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right.

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Phyllobates Aurotaenia
''Phyllobates aurotaenia'' is a member of the frog family Dendrobatidae, which are found in the tropical environments of Central and South America. First described by zoologist George Albert Boulenger in 1913, ''P. aurotaenia'' is known for being the third most poisonous frog in the world. It is the smallest of the poison dart frogs in the ''Phyllobates'' genus and is endemic to the Pacific coast of Colombia. Wild specimens store batrachotoxin in glands in their skin, which can be fatal to humans in doses as small as 100 µg. The unique lethality of their poison is a trait often exploited by certain Native American peoples of Colombia for hunting. The members of this species are characterized by: black dorsums, sometimes covered by orange suffusions; green, yellow, orange, or brownish gold dorsolateral stripes; and black abdomens with blue or green dots. The name ''Phyllobates aurotaenia'' is currently applied to two forms: a smaller, large-stripe form and a larger, small-st ...
