Broad-snouted Caiman
The broad-snouted caiman (''Caiman latirostris'') is a crocodilian in the family Alligatoridae found in eastern and central South America, including southeastern Brazil, northern Argentina, Uruguay, Paraguay, and Bolivia. It is found mostly in freshwater marshes, swamps, and mangroves, usually in still or very slow-moving waters. It will often use man-made cow ponds.Britton, A. ''Caiman latirostris'' (Daudin, 1801). ''Crocodilian Species List''.http://www.flmnh.ufl.edu/cnhc/csp_clat.htm. 2009. Characteristics In the wild, adults normally grow to in length, but a few old males have been recorded to reach up to . Captive adults were found to have weighed . Most tend to be of a light olive-green color. A few individuals have spots on their faces. The most notable physical characteristic is the broad snout from which its name is derived. Borteiro et al 2009 studied the food habits of ''C. latirostris''. The snout is well adapted to rip through the dense vegetation of the marshes. Du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Ectotherm
An ectotherm (from the Greek () "outside" and () "heat") is an organism in which internal physiological sources of heat are of relatively small or of quite negligible importance in controlling body temperature.Davenport, John. Animal Life at Low Temperature. Publisher: Springer 1991. Such organisms (for example frogs) rely on environmental heat sources, which permit them to operate at very economical metabolic rates. Some of these animals live in environments where temperatures are practically constant, as is typical of regions of the abyssal ocean and hence can be regarded as homeothermic ectotherms. In contrast, in places where temperature varies so widely as to limit the physiological activities of other kinds of ectotherms, many species habitually seek out external sources of heat or shelter from heat; for example, many reptiles regulate their body temperature by basking in the sun, or seeking shade when necessary in addition to a whole host of other behavioral thermo ...

Crocodilians Of South America
Crocodilia (or Crocodylia, both ) is an order of mostly large, predatory, semiaquatic reptiles, known as crocodilians. They first appeared 95 million years ago in the Late Cretaceous period (Cenomanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the order's total group, the clade Pseudosuchia, appeared about 250 million years ago in the Early Triassic period, and diversified during the Mesozoic era. The order Crocodilia includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae), and the gharial and false gharial (family Gavialidae). Although the term 'crocodiles' is sometimes used to refer to all of these, crocodilians is a less ambiguous vernacular term for members of this group. Large, solidly built, lizard-like reptiles, crocodilians have long flattened snouts, laterally compressed tails, and eyes, ears, and nostrils at the top of the ...

Rio De Janeiro
Rio de Janeiro ( , , ; literally 'River of January'), or simply Rio, is the capital of the state of the same name, Brazil's third-most populous state, and the second-most populous city in Brazil, after São Paulo. Listed by the GaWC as a beta global city, Rio de Janeiro is the sixth-most populous city in the Americas. Part of the city has been designated as a World Heritage Site, named "Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea", on 1 July 2012 as a Cultural Landscape. Founded in 1565 by the Portuguese, the city was initially the seat of the Captaincy of Rio de Janeiro, a domain of the Portuguese Empire. In 1763, it became the capital of the State of Brazil, a state of the Portuguese Empire. In 1808, when the Portuguese Royal Court moved to Brazil, Rio de Janeiro became the seat of the court of Queen Maria I of Portugal. She subsequently, under the leadership of her son the prince regent João VI of Portugal, raised Brazil to the dignity of a k ...

Recreio Dos Bandeirantes
Recreio dos Bandeirantes (or simply Recreio) is both the name of a beach and neighborhood in the West Zone of Rio de Janeiro, Brazil. It is a recent development, with no skyscrapers, and the area also contains jungles atop rocky cliffs and hills. High waves permit surfing at Recreio Beach and the white sand beach is used by beach volleyball players. It is about 35 km from the Rio de Janeiro city centre, and most of the people living there are middle-class and high middle-class families, who moved in trying to escape the growing violence of both the North and South Zones. Apocryphally, the neighborhood received the name Recreio dos Bandeirantes, or " Bandeirantes' Leisure" because the company that mapped and hired a real estate agent to sell lots there had that name. Another version says that many of the newcomers were from São Paulo, the city from which the Bandeiras departed in colonial times, and therefore Paulistas are associated with them. Still another version states that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barra Da Tijuca
Barra da Tijuca () (usually known as Barra) is an upper-class neighborhood or bairro in the Rio de Janeiro#West Zone, West Zone of Rio de Janeiro, Brazil, located in the western portion of the city on the Atlantic Ocean. Barra is well known for its beaches, its many lakes and rivers, and its lifestyle. This neighbourhood represents 4.7% of the city population and 13% of the total area of Rio de Janeiro. Barra da Tijuca is classified as one of the most developed places in Brazil, with one of the highest Human Development Indexes (HDI) in the country, as measured in the 2000 Brazil Census. Unlike the South Zone and Rio's Downtown, Barra da Tijuca, built only 30 years ago, follows the Modernist standards, with large boulevards creating the major transit axis. The area's masterplan was designed by Lúcio Costa, known for his work on Brasília, and creates a region filled with many gardens, shopping malls, apartment buildings and large mansions. In recent years, due to the rapid develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tegu
Tegu is a common name of a number of species of lizards that belong to the families Teiidae and Gymnophthalmidae. Tegus are native to Central and South America. They occupy a variety of habitats and are known for their large size and predatory habits. Description Tegus are usually mainly black and some have yellow, reddish or white bands along their backs. Others have lines going down their bodies and unique markings along their top. Their body shape is aerodynamic with long tails and strong legs. Most tegus grow to about a metre long but the black and white tegu (''T. Merianae'') can grow to about 1.3 metres. Tegus use their tongues and vomeronasal organ to find chemical cues associated with their prey and other lizards. A vomeronasal organ is an organ of chemoreception located in the main nasal chamber. Tegus can survive in rainforests, savannas, swamps, meadows, and open fields. Tegus are omnivores and eats seeds, berries, fruits, small rodents, insects, eggs, amphibians, ...

Herpetologists League
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists and He ...
