Phyllobates Bicolor01
''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 with ... [...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 endemism, endemic from 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 considered to be the most poisonous extant animal species 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.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea
Papua New Guinea, officially the Independent State of Papua New Guinea, is an island country in Oceania that comprises the eastern half of the island of New Guinea and offshore islands in Melanesia, a region of the southwestern Pacific Ocean north of Australia. It has Indonesia–Papua New Guinea border, a land border with Indonesia to the west and neighbours Australia to the south and the Solomon Islands to the east. Its capital, on its southern coast, is Port Moresby. The country is the world's third largest list of island countries, island country, with an area of . The nation was split in the 1880s between German New Guinea in the North and the Territory of Papua, British Territory of Papua in the South, the latter of which was ceded to Australia in 1902. All of present-day Papua New Guinea came under Australian control following World War I, with the legally distinct Territory of New Guinea being established out of the former German colony as a League of Nations mandate.

Phyllobates Samperi
''Phyllobates samperi'', formerly known as sp. aff. ''aurotaenia'' is a new species of hypertoxic poison dart frog, once cited as the "red" form of '' Phyllobates aurotaenia''. It resembles in size and to some extent in colouration to ''P. aurotaenia'', but genetically it is the sister species of the "terrible" frog '' P. terribilis''. It can be distinguished from ''P. aurotaenia'' by the absence of abundant blue or silver specks or marbling in the venter and limbs, its uniform black or bluish-black body, and its orange or red, rather than green or yellow, stripes. The species was named to honour Colombian biologist Cristian Samper, for his lasting impact on the world of conservation, overseeing initiatives that span across 65 countries. He is considered a respected figure in the intersection of science, governance, and activism. Distribution The species is known to occur in the wet forests along the lower San Juan and Dagua river basins in the vicinities of Buenaventura, Vall ...

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 (1834–1969), 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 ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

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 ...
