Eleutherodactylus Jaumei
''Eleutherodactylus jaumei'' is a species of frog in the family Eleutherodactylidae. This critically endangered species is endemic to a tiny area in Sierra Maestra in southeastern Cuba, where it mostly lives in closed mesic forest. ''E. jaumei'' is relatively brightly marked in yellow-orange and very small, up to in snout–to–vent length. It is part of a closely related Cuban group that contains five additional described species ('' E. cubanus'', '' E. etheridgei'', '' E. iberia'', '' E. limbatus'' and '' E. orientalis'') and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic (at least ''E. iberia'' and ''E. orientalis'' have alkaloid Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom.

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-striped Pygmy Eleuth
The yellow-striped pygmy eleuth (''Eleutherodactylus limbatus''), also known as the yellow-striped dwarf frog, is a species of frog in the family Eleutherodactylidae from closed mesic and xeric forests in Cuba. The yellow-striped pygmy eleuth is relatively brightly marked in orange-yellow and among the smallest frogs in the world, up to in snout–to–vent length with males marginally smaller than females. It is part of a closely related Cuban group that contains five additional described species ('' E. cubanus'', '' E. etheridgei'', '' E. iberia'', '' E. jaumei'' and '' E. orientalis'') and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic (at least ''E. iberia'' and ''E. orientalis'' have alkaloid toxins in their skin). Among these, the yellow-striped pygmy eleuth is unique in being quite widespread in Cuba, whereas the others all have very small ranges in the eastern part of the island. Mating calls and r ...

Amphibians Of Cuba
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Endemic Fauna Of Cuba
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleutherodactylus
''Eleutherodactylus'' is a genus of frogs in the family Eleutherodactylidae.Hedges, S. B., W. E. Duellman, and M. P. Heinicke . 2008. New World direct-developing frogs (Anura: Terrarana): molecular phylogeny, classification, biogeography, and conservation. Zootaxa 1737: 1-182. Many of the 200 species of the genus are commonly known as "rain frogs" or "robber frogs", due to their sharp, high-pitched, insect-like calls. The best-known species is the common coquí (''E. coqui''), which is both a national symbol of Puerto Rico and a notorious invasive species in Hawaii. Two ''Eleutherodactylus'' species, '' E. limbatus'' and '' E. iberia'', are among the smallest known frogs, measuring only 8.5 mm in length (only slightly larger than ''Paedophryne amauensis'', which measures around 7.7 mm). Etymology The name "Eleutherodactylus" is derived from the Greek words for ‘free-toed’, composed of the Ancient Greek ' (, ‘free, unbound’) and ' (, ‘finger, toe’). Most sp ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

Aposematic
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undescribed Taxon
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a '' nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp"., but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleutherodactylus Orientalis
''Eleutherodactylus orientalis'', the Oriental robber frog or Baracoa dwarf frog, is a species of frog in the family Eleutherodactylidae. It is endemic to the vicinity of El Yunque, Baracoa, in easternmost Cuba. Although locally common, it requires undisturbed moist forest and has a tiny range, making it critically endangered from habitat loss and degradation. ''E. orientalis'' is relatively brightly marked in yellow and very small, females averaging in snout–to–vent length and males . It is part of a closely related Cuban group that contains five additional described species ('' E. cubanus'', '' E. etheridgei'', '' E. iberia'', '' E. jaumei'' and '' E. limbatus'') and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic (at least ''E. iberia'' and ''E. orientalis'' have alkaloid Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom.

Monte Iberia Eleuth
The Monte Iberia eleuth (''Eleutherodactylus iberia''), also known as the Monte Iberia dwarf frog, is a species of eleutherodactylid frog. It is critically endangered and endemic to rainforest in a small part of easternmost Cuba. It is the smallest frog in the Northern Hemisphere and the third smallest frog in the world, at about in snout–to–vent length (only a few members of the Southern Hemisphere genera '' Brachycephalus'', ''Mini'', '' Paedophryne'' and ''Stumpffia'' are smaller). It was first discovered in 1993 on Mount Iberia in the Holguín Province, from which it gets its name. Much remains unknown about this small creature. It is part of a closely related Cuban group that contains five additional described species ('' E. cubanus'', '' E. etheridgei'', '' E. jaumei'', '' E. limbatus'' and '' E. orientalis'') and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic (at least ''E. iberia'' and ''E. or ...

Eleutherodactylidae
The Eleutherodactylidae are a family of direct-developing frogs native to northern South America, the Caribbean, and southernmost North America. They are sometimes known under the common name rain frogs. Formerly the subfamily Eleutherodactylinae of the family Leptodactylidae, it was raised to the family status following a major revision of New World direct-developing frogs in 2008. As currently defined, the family has more than 200 species (as of 2014, 206 or 207 species). Eleutherodactylid frogs vary considerably in size, from the minuscule ''Eleutherodactylus iberia'' (female snout–vent length ) to the relative giant '' E. inoptatus'' (female snout–vent length ). Except for the ovoviviparous '' E. jasperi'', these frogs have direct development: no free-living tadpole stage exists; instead, eggs develop directly into small froglets. Subfamilies and genera The two subfamilies and four genera are: * Eleutherodactylinae Lutz, 1954 (216 species) ** ''Diasporus'' Hedges, Duell ...
