Argentine Horned Frog
The Argentine horned frog (''Ceratophrys ornata''), also known as the Argentine wide-mouthed frog, ornate horned frog, ornate horned toad, or the ornate pacman frog, is a species of frog in the family Ceratophryidae. The species is endemic to South America. It is the most common species of horned frog, in the grasslands of Argentina, Uruguay and Brazil. A voracious eater, it will attempt to swallow anything that moves close to its wide mouth, such as insects, rodents, lizards, and other frogs, even if this predator would suffocate in the process. It is also kept as an exotic pet. The nickname "pacman frog" is a reference to the popular 1980's arcade game '' Pac-Man'', where Pac-Man himself eats quite a lot, and has a mouth that takes up most of its body, much like the Argentine horned frog. Description The females of ''C. ornata'' can grow to be 16.5 centimeters (6.5 inches) snout to vent (SV) and the males 11.5 centimeters (4.5 in) SV. The average lifespan is 6 to 7 yea ...

Thomas Bell (zoologist)
Thomas Hornsey Bell FRS FLS (11 October 1792 – 13 March 1880) was an English zoologist, dental surgeon A dentist, also known as a dental surgeon, is a health care professional who specializes in dentistry (the diagnosis, prevention, management, and treatment of diseases and conditions of the oral cavity and other aspects of the craniofacial com ... and writer, born in Poole, Dorset, England. Career Bell, like his mother Susan, took a keen interest in natural history which his mother also encouraged in his younger cousin Philip Henry Gosse. Bell left Poole in 1813 for his training as a dental surgeon in London. He is listed in 1817 as having an address at number 17 Fenchurch Street, and as being a committee member of the newly formed London Peace Society. By 1819 his address is given as 18 Bucklersbury, also in the city of London. He combined two careers, becoming Professor of Zoology at King's College London in 1836 (on the strength of amateur research) and lecturing o ...

Asphyxia
Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects primarily the tissues and organs. There are many circumstances that can induce asphyxia, all of which are characterized by the inability of a person to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death. In 2015, about 9.8 million cases of unintentional suffocation occurred which resulted in 35,600 deaths. The word asphyxia is from Ancient Greek "without" and , "squeeze" (throb of heart). Causes Situations that can cause asphyxia include but are not limited to: airway obstruction, the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; envir ...

Amphibians Of Brazil
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 ...

Ceratophrys
''Ceratophrys'' is a genus of frogs in the family Ceratophryidae. They are also known as South American horned frogs as well as Pacman frogs due to their characteristic round shape and large mouth, reminiscent of the video game character Pac-Man. Species There are eight species: Sex differentiation The female frog will typically not "chirp" or "croak" as often as males, but does sometimes. Males frequently have spotted chests, and at about a year old the males develop spots on their "pads" or "fingers." Males will also sometimes have subtle pads on their front legs during mating season, as well as making a sound similar to a cicada to call to their mates. The female frog is also generally larger than the male frog. Care in captivity In captivity, ''C. cranwelli'', ''C. ornata'' and ''C. cornuta'' are the most popular species, along with the "fantasy frog", a captive-produced hybrid between ''C. cranwelli'' and ''C. cornuta''. These frogs can live in a 10-gallon aquarium for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argentine
Argentines (mistakenly translated Argentineans in the past; in Spanish (masculine) or (feminine)) are people identified with the country of Argentina. This connection may be residential, legal, historical or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being ''Argentine''. Argentina is a multiethnic and multilingual society, home to people of various ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other immigr ...

Pac-Man
originally called ''Puck Man'' in Japan, is a 1980 maze action video game developed and released by Namco for arcades. In North America, the game was released by Midway Manufacturing as part of its licensing agreement with Namco America. The player controls Pac-Man, who must eat all the dots inside an enclosed maze while avoiding four colored ghosts. Eating large flashing dots called "Power Pellets" causes the ghosts to temporarily turn blue, allowing Pac-Man to eat them for bonus points. Game development began in early 1979, directed by Toru Iwatani with a nine-man team. Iwatani wanted to create a game that could appeal to women as well as men, because most video games of the time had themes of war or sports. Although the inspiration for the Pac-Man character was the image of a pizza with a slice removed, Iwatani has said he also rounded out the Japanese character for mouth, kuchi ( ja, 口). The in-game characters were made to be cute and colorful to appeal to younger p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exotic Pet
An exotic pet is a pet which is relatively rare or unusual to keep, or is generally thought of as a wild species rather than as a domesticated pet. The definition varies by culture, location, and over time—as animals become firmly enough established in the world of animal fancy, they may no longer be considered ''exotic''. Definitions The definition is an evolving one; some rodents, reptiles, and amphibians have become firmly enough established in the world of animal fancy to no longer be considered exotic. Sometimes any unique or wild-looking pet (including common domestic animals such as the ferret and the rat) is considered an exotic pet. "Exotic" often refers to a species which is not native or indigenous to the owner's locale, and "pet" is a companion animal living with people. However, many use the term to include native species as well (e.g., snakes may sometimes be considered exotic as pets even in places where they are found in the wild). The international organi ...
