Calyptocephalella
''Calyptocephalella'' is a genus of frogs in the family Calyptocephalellidae. It is represented by a single living species, ''Calyptocephalella gayi'', commonly known as the helmeted water toad, Chilean helmeted bull frog or wide-mouth toad. Additionally, there are a few extinct species that only are known from Late Cretaceous and Paleogene fossil remains from Patagonia in South America and in the Antarctic Peninsula (at times when it was warmer and wetter). The helmeted water toad living today is aquatic to semi-aquatic, and found in deep ponds and reservoirs in central Chile and possibly adjacent west-central Argentina.AmphibiaWeb: Calyptocephalella gayi.' Retrieved 21 March 2015. This very large toad typically weighs up to , but sometimes considerably more. It's the world's second largest frog after the goliath frog. It is threatened by capture for human consumption, habitat loss, pollution, introduced species and the disease chytridiomycosis. It is often kept in herpetocultur ...

Calyptocephalellidae
The Calyptocephalellidae are a family of toads (although not true members of the Bufonidae) found in Chile containing two living genera, ''Calyptocephalella'' and ''Telmatobufo.'' The genus ''Calyptocephalella'' contains one living species, the helmeted water toad (''C. gayi''), which is very large and mostly aquatic. The genus ''Telmatobufo'' contains four species, '' T. australis'', '' T. bullocki'', '' T. ignotus'', and '' T. venustus''. All five living species within the family are considered threatened, with ''T. bullocki'' and ''T. venustus'' being classified as critically endangered. The family has been present in southern South America since the end of the Cretaceous and were present in the Antarctic Peninsula during the Eocene. While originally widespread in Patagonia east of the Andes, they later became extinct in this region after the Late Miocene, likely due to increasingly cold and arid conditions. A particularly large indeterminate fossil species is known from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telmatobius Macrostomus
''Telmatobius macrostomus'', also known as the Lake Junin (giant) frog or Andes smooth frog, is a very large and endangered species of frog in the family Telmatobiidae.Angulo, A. (2008).

Goliath Frog
The goliath frog (''Conraua goliath''), otherwise known commonly as the giant slippery frog and the goliath bullfrog, is a species of frog in the family Conrauidae. The goliath frog is the largest living frog. Specimens can grow up to in length from snout to vent, and weigh up to . This species has a relatively small habitat range in Cameroon and Equatorial Guinea. Its numbers are dwindling due to habitat destruction and its collection for food and the pet trade. Description Sexual dimorphism between the sexes is minimal. In a sample of 15 individuals, weights ranged between , and snout-vent lengths were between . Their eyes can be nearly in diameter. The conspicuous tympanum has a diameter around and is separated from the eye by about in adults. Goliath frog eggs and tadpoles are about the same size as other frogs despite their very large adult form. A lateral fold extends from the eye to the posterior portion of the tympanum. Toes are fully webbed, with large interdigi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Olive (color)
Olive is a dark yellowish-green color, like that of unripe or green olives. As a color word in the English language, it appears in late Middle English. Shaded toward gray, it becomes olive drab. Variations Olivine Olivine is the typical color of the mineral olivine. The first recorded use of ''olivine'' as a color name in English was in 1912. Olive drab Olive drab is variously described as a "dull olive-green colour" (''Oxford English Dictionary'');''Oxford English Dictionary'', 5th Edition, 1982 "a shade of greenish-brown" (''Webster's New World Dictionary''); "a dark gray-green" (''MacMillan English dictionary''); "a grayish olive to dark olive brown or olive gray" (''American Heritage Dictionary''); or "A dull but fairly strong gray-green color" (''Collins English Dictionary''). It was widely used as a camouflage color for uniforms and equipment in the armed forces, particularly by the U.S. Army during the Second World War. The first recorded use of ''olive ...

Titicaca Water Frog
''Telmatobius culeus'', commonly known as the Titicaca water frog, is a medium-large to very large and endangered species of frog in the family Telmatobiidae. It is entirely aquatic and only found in the Lake Titicaca basin, including rivers that flow into it and smaller connected lakes like Arapa, Lagunillas and Saracocha, in the Andean highlands of Bolivia and Peru. In reference to its excessive amounts of skin, it has jokingly been referred to as the Titicaca scrotum (water) frog. It is closely related to the more widespread and semiaquatic marbled water frog (''T. marmoratus''),Victoriano, Muñoz-Mendoza, Sáez, Salinas, Muñoz-Ramírez, Sallaberry, Fibla and Méndez (2015). ''Evolution and Conservation on Top of the World: Phylogeography of the Marbled Water Frog (Telmatobius marmoratus Species Complex; Anura, Telmatobiidae) in Protected Areas of Chile.''

Mountain Chicken
''Leptodactylus fallax'', commonly known as the mountain chicken or giant ditch frog, is a critically endangered species of frog that is native to the Caribbean islands of Dominica and Montserrat. The population declined by at least 80% from 1995 to 2004, with further significant declines later. A tiny wild population remains on Dominica where there are efforts to preserve it, but few or none survive in the wild on Montserrat and its survival now relies on a captive breeding project involving several zoos. The initial decline was linked to hunting for human consumption, along with habitat loss and natural disasters, but the most serious threat now appears to be the fungal disease chytridiomycosis, which was the primary cause of the most recent rapid decline. On Montserrat it is known as the mountain chicken, while on Dominica it is known as the crapaud. Etymology The mountain chicken is nicknamed such after being preyed upon as a local delicacy on the islands of Montserrat and D ...

American Bullfrog
The American bullfrog (''Lithobates catesbeianus''), often simply known as the bullfrog in Canada and the United States, is a large true frog native to eastern North America. It typically inhabits large permanent water bodies such as swamps, ponds, and lakes. Bullfrogs can also be found in man made habitats such as pools, koi ponds, canals, ditches and culverts. The bullfrog gets its name from the sound the male makes during the breeding season, which sounds similar to a bull bellowing. The bullfrog is large and is commonly eaten throughout its range, especially in the southern United States where they are plentiful. Their presence as a food source has led to bullfrogs being distributed around the world outside of their native range. Bullfrogs have been introduced into the Western United States, South America, Western Europe, China, Japan, and southeast Asia. In these places they are invasive species due to their voracious appetite and the large number of eggs they produce, havi ...

Smooth-sided Toad
The smooth-sided toad or spotted toad (''Rhaebo guttatus''), formerly known as ''Bufo guttatus'', is a species of toad in the family Bufonidae. It is found in the Amazonian Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela, as well as the Guianas (French Guiana, Guyana, and Suriname). Specimens from southern Peru, Bolivia, and Brazil might represent ''Rhaebo ecuadorensis'' described in 2012. Description Males growth to about snout–vent length. Females are larger, at up to , possibly even , in snout–vent length. The dorsal color is cream colored or very light brown to reddish brown. The belly is a darker shade. The species has a characteristically prominent preocular ridge that is present even in juveniles. The smooth sided toad secretes a toxin from a gland behind their eyes known as a bufotoxin, it has been known to cause heart failure in humans if ingested. This toxin is the toad's main line of defense against predators. Habitat and conservation Its natural habita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinella Diptycha
''Rhinella diptycha'', sometimes referred to as Cope's toad, Schneider's toad, cururu toad, or rococo toad, is a toad found in northern Argentina, Paraguay, Uruguay, eastern Bolivia, and eastern and southern Brazil. It is one of three rather similar species sometimes referred to as "cururu toads" in Brazil, the others being '' R. jimi'' and '' R. marina'' (cane toad). Like those, ''R. diptycha'' is a large toad, females up to in snout–to–vent length and males up to . ''Rhinella diptycha'' is a widespread and very common species that occurs in a variety of habitats but most commonly in open and urban ones. It breeds in permanent and temporary ponds, preferring ones without much vegetation. Its natural habitats include dry savanna, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native ...

Colorado River Toad
The Colorado River toad (''Incilius alvarius''), formerly known as the Sonoran Desert toad, is found in northern Mexico and the southwestern United States. It exudes toxins from glands within its skin that have psychoactive properties. Description The Colorado River toad can grow to about long and is the largest toad in the United States apart from the non-native cane toad (''Rhinella marina''). It has a smooth, leathery skin and is olive green or mottled brown in color. Just behind the large golden eye with horizontal pupil is a bulging kidney-shaped parotoid gland. Below this is a large circular pale green area which is the tympanum or ear drum. By the corner of the mouth there is a white wart and there are white glands on the legs. All these glands produce toxic secretions. Its call is described as, "a weak, low-pitched toot, lasting less than a second." Dogs that have attacked toads have suffered paralysis or even death.
