A frog is any member of a diverse and carnivorous group of short-bodied, tailless amphibians composing the order Anura. The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforests. There are accounting for over 85 % of extant amphibian species, they are 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 or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, no tail. Frogs have glandular skin, with secretions ranging from distasteful to toxic, their skin varies in colour from well-camouflaged dappled brown and green to vivid patterns of bright red or yellow and black to show toxicity and ward off predators.
Adult frogs live on dry land. Frogs lay their eggs in water; the eggs hatch into aquatic larvae called tadpoles that have internal gills. They have specialized rasping mouth parts suitable for herbivorous, omnivorous or planktivorous diets; the life cycle is completed. A few species bypass the tadpole stage. Adult frogs have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on fruit. Frog skin has a rich microbiome, important to their health. Frogs are efficient at converting what they eat into body mass, they are an important food source for predators and part of the food web dynamics of many of the world's ecosystems. The skin is semi-permeable, making them susceptible to dehydration, so they either live in moist places or have special adaptations to deal with dry habitats. Frogs produce a wide range of vocalizations in their breeding season, exhibit many different kinds of complex behaviours to attract mates, to fend off predators and to survive.
Frogs are valued as food by humans and have many cultural roles in literature and religion. Frog populations have declined since the 1950s. More than one third of species are considered to be threatened with extinction and over 120 are believed to have become extinct since the 1980s; the number of malformations among frogs is on the rise and an emerging fungal disease, has spread around the world. Conservation biologists are working to resolve them; the use of the common names "frog" and "toad" has no taxonomic justification. From a classification perspective, all members of the order Anura are frogs, but only members of the family Bufonidae are considered "true toads"; the use of the term "frog" in common names refers to species that are aquatic or semi-aquatic and have smooth, moist skins. There are numerous exceptions to this rule; the European fire-bellied toad has a warty skin and prefers a watery habitat whereas the Panamanian golden frog is in the toad family Bufonidae and has a smooth skin.
The origin of the order name Anura — and its original spelling Anoures — is the Ancient Greek "alpha privative" prefix ἀν- "without", οὐρά, meaning "animal tail". It refers to the tailless character of these amphibians; the origins of the word frog are debated. The word is first attested in Old English as frogga, but the usual Old English word for the frog was frosc, it is agreed that the word frog is somehow related to this. Old English frosc remained in dialectal use in English as frosh and frosk into the nineteenth century, is paralleled in other Germanic languages, with examples in the modern languages including German Frosch, Icelandic froskur, Dutch vors; these words allow us to reconstruct a Common Germanic ancestor *froskaz. The third edition of the Oxford English Dictionary finds that the etymology of *froskaz is uncertain, but agrees with arguments that it could plausibly derive from a Proto-Indo-European base along the lines of *preu = "jump". How Old English frosc gave rise to frogga is, uncertain, as the development does not involve a regular sound-change.
Instead, it seems that there was a trend in Old English to coin nicknames for animals ending in -g, with examples—themselves all of uncertain etymology—including dog, pig and wig. Frog appears to have been adapted from frosc as part of this trend. Meanwhile, the word toad, first attested as Old English tādige, is unique to English and is of uncertain etymology, it is the basis for the word tadpole, first attested as Middle English taddepol meaning'toad-head'. About 88% of amphibian species are classified in the order Anura; these include over 7,000 species in 56 families, of which the Craugastoridae, Hylidae and Bufonidae are the richest in species. The Anura include any fossil species that fit within the anuran definition; the characteristics of anuran adults include: 9 or fewer presacral vertebrae, the presence of a urostyle formed of fused vertebrae, no tail, a long and forward-sloping ilium, shorter fore limbs than hind limbs and ulna fused and fibula fused, elongated an
The Caribbean is a region of The Americas that consists of the Caribbean Sea, its islands and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, north of South America. Situated on the Caribbean Plate, the region comprises more than 700 islands, islets and cays; these islands form island arcs that delineate the eastern and northern edges of the Caribbean Sea. The Caribbean islands, consisting of the Greater Antilles on the north and the Lesser Antilles on the south and east, are part of the somewhat larger West Indies grouping, which includes the Lucayan Archipelago; the Lucayans and, less Bermuda, are sometimes considered Caribbean despite the fact that none of these islands border the Caribbean Sea. In a wider sense, the mainland countries and territories of Belize, the Caribbean region of Colombia, the Yucatán Peninsula, Margarita Island, the Guyanas, are included due to their political and cultural ties with the region.
Geopolitically, the Caribbean islands are regarded as a subregion of North America and are organized into 30 territories including sovereign states, overseas departments, dependencies. From December 15, 1954, to October 10, 2010, there was a country known as the Netherlands Antilles composed of five states, all of which were Dutch dependencies. From January 3, 1958, to May 31, 1962, there was a short-lived political union called the West Indies Federation composed of ten English-speaking Caribbean territories, all of which were British dependencies; the West Indies cricket team continues to represent many of those nations. The region takes its name from that of the Caribs, an ethnic group present in the Lesser Antilles and parts of adjacent South America at the time of the Spanish conquest of the Americas; the two most prevalent pronunciations of "Caribbean" outside the Caribbean are, with the primary stress on the third syllable, with the stress on the second. Most authorities of the last century preferred the stress on the third syllable.
This is the older of the two pronunciations, but the stressed-second-syllable variant has been established for over 75 years. It has been suggested that speakers of British English prefer while North American speakers more use, but major American dictionaries and other sources list the stress on the third syllable as more common in American English too. According to the American version of Oxford Online Dictionaries, the stress on the second syllable is becoming more common in UK English and is considered "by some" to be more up to date and more "correct"; the Oxford Online Dictionaries claim that the stress on the second syllable is the most common pronunciation in the Caribbean itself, but according to the Dictionary of Caribbean English Usage, the most common pronunciation in Caribbean English stresses the first syllable instead. The word "Caribbean" has multiple uses, its principal ones are political. The Caribbean can be expanded to include territories with strong cultural and historical connections to slavery, European colonisation and the plantation system.
The United Nations geoscheme for the Americas presents the Caribbean as a distinct region within the Americas. Physiographically, the Caribbean region is a chain of islands surrounding the Caribbean Sea. To the north, the region is bordered by the Gulf of Mexico, the Straits of Florida and the Northern Atlantic Ocean, which lies to the east and northeast. To the south lies the coastline of the continent of South America. Politically, the "Caribbean" may be centred on socio-economic groupings found in the region. For example, the bloc known as the Caribbean Community contains the Co-operative Republic of Guyana, the Republic of Suriname in South America and Belize in Central America as full members. Bermuda and the Turks and Caicos Islands, which are in the Atlantic Ocean, are associate members of the Caribbean Community; the Commonwealth of the Bahamas is in the Atlantic and is a full member of the Caribbean Community. Alternatively, the organisation called the Association of Caribbean States consists of every nation in the surrounding regions that lie on the Caribbean, plus El Salvador, which lies on the Pacific Ocean.
According to the ACS, the total population of its member states is 227 million people. The geography and climate in the Caribbean region varies: Some islands in the region have flat terrain of non-volcanic origin; these islands include Aruba, Curaçao, Bonaire, the Cayman Islands, Saint Croix, the Bahamas, Antigua. Others possess rugged towering mountain-ranges like the islands of Saint Martin, Hispaniola, Puerto Rico, Dominica, Saba, Sint Eustatius, Saint Kitts, Saint Lucia, Saint Thomas, Saint John, Grenada, Saint Vincent, Guadeloupe and Trinidad and Tobago. Definitions of the terms Greater Antilles and Lesser Antilles vary; the Virgin Islands as part of the Puerto Rican bank are sometimes included with the Greater Antilles. The term Lesser Antilles is used to define an island arc that includes Grenada but excludes Trinidad and Tobago and the Leeward Antilles; the waters of the Caribbean Sea host large, migratory schools of fish and coral reef
Chondrohierax is a genus of birds of prey in the family Accipitridae. Its two members, the hook-billed kite and the Cuban kite, are considered to be conspecific; the hook-billed kite is widespread in the warmer parts of the Americas, while the Cuban kite is a critically endangered Cuban endemic.

Mammals are vertebrate animals constituting the class Mammalia, characterized by the presence of mammary glands which in females produce milk for feeding their young, a neocortex, fur or hair, three middle ear bones. These characteristics distinguish them from reptiles and birds, from which they diverged in the late Triassic, 201–227 million years ago. There are around 5,450 species of mammals; the largest orders are the rodents and Soricomorpha. The next three are the Primates, the Cetartiodactyla, the Carnivora. In cladistics, which reflect evolution, mammals are classified as endothermic amniotes, they are the only living Synapsida. The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period around 300 million years ago, this group diverged from the sauropsid line that led to today's reptiles and birds; the line following the stem group Sphenacodontia split off several diverse groups of non-mammalian synapsids—sometimes referred to as mammal-like reptiles—before giving rise to the proto-mammals in the early Mesozoic era.
The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of non-avian dinosaurs, have been among the dominant terrestrial animal groups from 66 million years ago to the present. The basic body type is quadruped, most mammals use their four extremities for terrestrial locomotion. Mammals range in size from the 30–40 mm bumblebee bat to the 30-meter blue whale—the largest animal on the planet. Maximum lifespan varies from two years for the shrew to 211 years for the bowhead whale. All modern mammals give birth to live young, except the five species of monotremes, which are egg-laying mammals; the most species-rich group of mammals, the cohort called placentals, have a placenta, which enables the feeding of the fetus during gestation. Most mammals are intelligent, with some possessing large brains, self-awareness, tool use. Mammals can communicate and vocalize in several different ways, including the production of ultrasound, scent-marking, alarm signals and echolocation.
Mammals can organize themselves into fission-fusion societies and hierarchies—but can be solitary and territorial. Most mammals are polygynous. Domestication of many types of mammals by humans played a major role in the Neolithic revolution, resulted in farming replacing hunting and gathering as the primary source of food for humans; this led to a major restructuring of human societies from nomadic to sedentary, with more co-operation among larger and larger groups, the development of the first civilizations. Domesticated mammals provided, continue to provide, power for transport and agriculture, as well as food and leather. Mammals are hunted and raced for sport, are used as model organisms in science. Mammals have been depicted in art since Palaeolithic times, appear in literature, film and religion. Decline in numbers and extinction of many mammals is driven by human poaching and habitat destruction deforestation. Mammal classification has been through several iterations since Carl Linnaeus defined the class.
No classification system is universally accepted. George Gaylord Simpson's "Principles of Classification and a Classification of Mammals" provides systematics of mammal origins and relationships that were universally taught until the end of the 20th century. Since Simpson's classification, the paleontological record has been recalibrated, the intervening years have seen much debate and progress concerning the theoretical underpinnings of systematization itself through the new concept of cladistics. Though field work made Simpson's classification outdated, it remains the closest thing to an official classification of mammals. Most mammals, including the six most species-rich orders, belong to the placental group; the three largest orders in numbers of species are Rodentia: mice, porcupines, beavers and other gnawing mammals. The next three biggest orders, depending on the biological classification scheme used, are the Primates including the apes and lemurs. According to Mammal Species of the World, 5,416 species were identified in 2006.
These were grouped into 153 families and 29 orders. In 2008, the International Union for Conservation of Nature completed a five-year Global Mammal Assessment for its IUCN Red List, which counted 5,488 species. According to a research published in the Journal of Mammalogy in 2018, the number of recognized mammal species is 6,495 species included 96 extinct; the word "mammal" is modern, from the scientific name Mammalia coined by Carl Linnaeus in 1758, derived from the Latin mamma. In an influential 1988 paper, Timothy Rowe defined Mammalia phylogenetically as the crown group of mammals, the clade consisting of the most recent common ancestor of living monotremes and therian m
Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Texas shares borders with the U. S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast. Houston is the most populous city in Texas and the fourth largest in the U. S. while San Antonio is the second-most populous in the state and seventh largest in the U. S. Dallas–Fort Worth and Greater Houston are the fourth and fifth largest metropolitan statistical areas in the country, respectively. Other major cities include Austin, the second-most populous state capital in the U. S. and El Paso. Texas is nicknamed "The Lone Star State" to signify its former status as an independent republic, as a reminder of the state's struggle for independence from Mexico; the "Lone Star" can be found on the Texan state seal.
The origin of Texas's name is from the word taysha. Due to its size and geologic features such as the Balcones Fault, Texas contains diverse landscapes common to both the U. S. Southern and Southwestern regions. Although Texas is popularly associated with the U. S. southwestern deserts, less than 10% of Texas's land area is desert. Most of the population centers are in areas of former prairies, grasslands and the coastline. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the desert and mountains of the Big Bend; the term "six flags over Texas" refers to several nations. Spain was the first European country to claim the area of Texas. France held a short-lived colony. Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the union as the 28th state; the state's annexation set off a chain of events that led to the Mexican–American War in 1846.
A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, joined the Confederate States of America on March 2nd of the same year. After the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. Four major industries shaped the Texas economy prior to World War II: cattle and bison, cotton and oil. Before and after the U. S. Civil War the cattle industry, which Texas came to dominate, was a major economic driver for the state, thus creating the traditional image of the Texas cowboy. In the 19th century cotton and lumber grew to be major industries as the cattle industry became less lucrative, it was though, the discovery of major petroleum deposits that initiated an economic boom which became the driving force behind the economy for much of the 20th century. With strong investments in universities, Texas developed a diversified economy and high tech industry in the mid-20th century.
As of 2015, it is second on the list of the most Fortune 500 companies with 54. With a growing base of industry, the state leads in many industries, including agriculture, energy and electronics, biomedical sciences. Texas has led the U. S. in state export revenue since 2002, has the second-highest gross state product. If Texas were a sovereign state, it would be the 10th largest economy in the world; the name Texas, based on the Caddo word táyshaʼ "friend", was applied, in the spelling Tejas or Texas, by the Spanish to the Caddo themselves the Hasinai Confederacy, the final -s representing the Spanish plural. The Mission San Francisco de los Tejas was completed near the Hasinai village of Nabedaches in May 1690, in what is now Houston County, East Texas. During Spanish colonial rule, in the 18th century, the area was known as Nuevo Reino de Filipinas "New Kingdom of the Philippines", or as provincia de los Tejas "province of the Tejas" also provincia de Texas, "province of Texas", it was incorporated as provincia de Texas into the Mexican Empire in 1821, declared a republic in 1836.
The Royal Spanish Academy recognizes both spellings and Texas, as Spanish-language forms of the name of the U. S. State of Texas; the English pronunciation with /ks/ is unetymological, based in the value of the letter x in historical Spanish orthography. Alternative etymologies of the name advanced in the late 19th century connected the Spanish teja "rooftile", the plural tejas being used to designate indigenous Pueblo settlements. A 1760s map by Jacques-Nicolas Bellin shows a village named Teijas on Trinity River, close to the site of modern Crockett. Texas is the second-largest U. S. state, with an area of 268,820 square miles. Though 10% larger than France and twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Zambia. Texas is in the south central part of the United States of America. Three of its borders are defined by rivers; the Rio Grande forms a natural border with the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the south.
The Red River forms a natural border with Arkansas to the north. The Sabine River forms a natural border with Louisiana to the east; the Texas Panhandle has an eastern border with Oklahoma at 100° W, a northern border with Oklahoma at 36°30' N and a western
Peruíbe is a municipality in the state of São Paulo in Brazil. It is part of the Metropolitan Region of Baixada Santista; the population is 65,226 in an area of 324.55 square kilometres. Peruíbe is located to the southwest of west of Santos. Peruíbe's urban area is along the Atlantic Ocean fronting its famous beach, one of the longest in the state; the urban area covers a small part of the municipality, with population growing steadily. Most of the area north of downtown Peruíbe is forested with trees, is hilly or mountainous as part of the Serra do Mar. An Indian Reservation named Terra Indígena Piaçagüera, home to the Guaraní tribe named Nhandhevá covers an area of 27.95 square kilometres with a perimeter of 38 km. The municipality contains part of the Tupiniquins Ecological Station, it contains the 359 hectares Ilha do Ameixal Area of Relevant Ecological Interest created in 1985. It contains a small part of the 84,425 hectares Juréia-Itatins Ecological Station, a protected area of well-preserved Atlantic Forest created in 1986.
It contains the 5,040 hectares Itinguçu State Park, created in 2006. It contains 91% of the 1,487 hectares Barra do Una Sustainable Development Reserve created in 2006; the municipality contains the 33 hectares Ilhas Queimada Pequena e Queimada Grande Area of Relevant Ecological Interest, created in 1985 to protect two islands off the coast. The Ilhas do Abrigo e Guararitama Wildlife Refuge protects two other islands in the Atlantic Ocean to the east of the town. Peruíbe in the Tupi language means river of the shark; as the region of Mongaguá, Peruibe belonged to the Itanhaém territory that stretched from São Vicente to Cananéia, both Portuguese villages founded during the colonial times. As Mongagua, Peruibe, as a municipality, was created back in the 20th century for administrative convenience. Back in the 16th century, the region of Peruibe would have had a bad reputation since most Tupiniquim Indians living there were put into slavery by the Portuguese, working in sugarcane plantations around São Vicente Island.
The Abarebebe as the Indigenous peoples called Father Leonardo Nunes, or "the priest that flies" – since he was seen walking on foot all around the long beach between Itanhaem and Peruibe, was the one who fought against this practice that hurt so many Indian families. He converted an Indian Chaser, killed by the Indians, dying as a martyr, it was there, on the rock of Abarebebe that the Jesuits built the first church of that part of the coast, named Church of Saint John Baptist that served as a school and refuge against the Indian attacks. The sacred objects were taken to Itanhaem. Nowadays Peruibe is a modern city presenting many luxury restaurants; the public interest for the city is rising since there is a nature reserve named Parque da Juréia, featuring pristine beaches, a "local caiçara" community of fishermen, sheltering an immense diversity of flora and fauna. The city is surrounded by the Sea Mountain Range the south end of which, near Barra do Una, is called the Juréia Massif. Peruíbe attracts many tourists throughout the year.
In Peruibe there are two areas of tourist interest: urban and ecological. The principal urban attractions are the Tower of TV and Mirante, Ruins of the Abarebebe, Flórida square, New Commercial Center-Padre Anchieta Avenue, Old Commercial Center-region of the Estação, Ambrósio Baldin Square and Portinho. Ecological tourist spots include the Rio Preto Bridge, Costão Beach, Mountain range of the Itatins, Quarter of the Guaraú, Guaraú River, Guaraú Beach, Bar of Una, Una River and Una Beach.
