Bufo
''Bufo'' is a genus of true toads in the amphibian family Bufonidae. As traditionally defined, it was a wastebasket genus containing a large number of toads from much of the world but following taxonomic reviews most of these have been moved to other genera, leaving only seventeen extant species from Europe, northern Africa and Asia in this genus, including the well-known common toad (''B. bufo''). Some of the genera that contain species formerly placed in ''Bufo'' are '' Anaxyrus'' (many North American species), '' Bufotes'' (European green toad and relatives), '' Duttaphrynus'' (many Asian species, including the Asian common toad introduced elsewhere), ''Epidalea'' (natterjack toad) and ''Rhinella'' (many Latin American species, including the cane toad introduced elsewhere). Description True toads have in common stocky figures and short legs, which make them relatively poor jumpers. Their dry skin is thick and "warty". Behind their eyes, ''Bufo'' species have wart-like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bufo Bankorensis
''Bufo bankorensis'' (vernacular names: Central Formosa toad, Bankor toad) is a species of toad in the family Bufonidae. It is endemic to Taiwan and widely distributed at elevations up to above sea level. There has been doubts about its separatedness from ''Bufo gargarizans'' from China and even other species, but it is currently considered a valid species. Description ''Bufo bankorensis'' is a large toad that can reach , even in snout–vent length. Females are larger than males. The snout is short. Dorsolateral ridge is absent. The tympanum is not prominent. The parotoid glands are kidney-shaped. Skin is rough and covered with pointed tubercles of various size. Coloration is light brown color with orange, yellow, or black markings. Habitat and conservation ''Bufo bankorensis'' are found in a range of habitats at elevations up to : broadleaf forests, cultivated fields, mixed forests, and orchards. They can be seen foraging on insects under street lights during rainy nights. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidalea
The natterjack toad (''Epidalea calamita'') is a toad native to sandy and heathland areas of Europe. Adults are 60–70 mm in length, and are distinguished from common toads by a yellow line down the middle of the back and parallel paratoid glands. They have relatively short legs, which gives them a distinctive gait, contrasting with the hopping movement of many other toad species. Natterjacks have a very loud and distinctive mating call amplified by the single vocal sac found under the chin of the male. Life history Natterjacks live for up to 15 years, and feed mainly on insects, especially beetles. At night, they move around open terrain with sparse vegetation, and their tracks can often be seen in loose sand. They move considerable distances each night, enabling the species to colonize new habitats very quickly. Reproduction The natterjack toad spawns between the end of April and July, laying strings of eggs in shallow, warm pools. Because the natterjack toad is ...

Asian Common Toad
''Duttaphrynus melanostictus'' is commonly called Asian common toad, Asian black-spined toad, Asian toad, black-spectacled toad, common Sunda toad, and Javanese toad. It is probably a complex of more than one true toad species that is widely distributed in South and Southeast Asia. The species grows to about long. Asian common toads breed during the monsoon, and their tadpoles are black. Young toads may be seen in large numbers after monsoon rains finish. Characteristics The top of the head has several bony ridges, along the edge of the snout (canthal ridge), in front of the eye (preorbital), above the eye (supraorbital), behind the eye (postorbital), and a short one between the eye and ear (orbitotympanic). The snout is short and blunt, and the space between the eyes is broader than the upper eyelid width. The ear drum or tympanum is very distinct and is at least as wide as two-thirds the diameter of the eye. The first finger is often longer than the second and the toes a ...

Parotoid Gland
The parotoid gland (alternatively, paratoid gland) is an external skin gland on the back, neck, and shoulder of toads and some frogs and salamanders. It can secrete a number of milky alkaloid substances (depending on the species) known collectively as bufotoxins, which act as neurotoxins to deter predation. These cutaneous glands are called parotoid as they are somewhat similarly positioned to mammalian parotid gland, although the latter have a different function, excreting saliva within the mouth rather than externally excreted defensive chemicals. A study of the parotoid glands of the Colorado River toad in 1976 found that the parotoid glands were "composed of numerous lobules", each of which is a separate unit with a lumen surrounded by a double cell layer. The cell layers have interlocking microvilli. The study found that the outer cell layer resembled smooth muscle cells, with some organelles hypothesised to "function in some aspects of venom synthesis, active cellular trans ...

Common Toad
The common toad, European toad, or in Anglophone parts of Europe, simply the toad (''Bufo bufo'', from Latin ''bufo'' "toad"), is a frog found throughout most of Europe (with the exception of Ireland, Iceland, and some Mediterranean islands), in the western part of North Asia, and in a small portion of Northwest Africa. It is one of a group of closely related animals that are descended from a common ancestral line of toads and which form a species complex. The toad is an inconspicuous animal as it usually lies hidden during the day. It becomes active at dusk and spends the night hunting for the invertebrates on which it feeds. It moves with a slow, ungainly walk or short jumps, and has greyish-brown skin covered with wart-like lumps. Although toads are usually solitary animals, in the breeding season, large numbers of toads converge on certain breeding ponds, where the males compete to mate with the females. Eggs are laid in gelatinous strings in the water and later hatch out into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bufotoxin
Bufotoxins are a family of toxic steroid lactones or substituted Substituted tryptamine, tryptamines of which some may or may not be toxic. They occur in the parotoid glands, skin, and poison of many toads (genus ''Bufo'') and other amphibians, and in some plants and mushrooms. The exact composition varies greatly with the specific source of the toxin. It can contain 5-MeO-DMT, bufagins, bufalin, bufotalin, bufotenin, bufothionine, dehydrobufotenine, epinephrine, norepinephrine, and serotonin. Some authors have also used the term ''bufotoxin'' to describe the conjugate of a bufagin with suberylarginine. The toxic substances found in toads can be divided by chemical structure in two groups: #bufadienolides, which are cardiac glycosides (e.g., bufotalin, bufogenin) #tryptamine-related substances (e.g., bufotenin) Toads known to secrete bufotoxin include the following: *''Colorado River toad, Bufo alvarius'' *''Bufo americanus'' *''Bufo arenarum'' *''Bufo asper'' *''Bufo blombergi ...

Bufo Andrewsi
The Asiatic toad or Chusan Island toad (''Bufo gargarizans'') is a species of toad endemic to East Asia. The species was previously classified as ''Bufo bufo gargarizans'', a subspecies of the common toad. Distribution and habitat It is common in China (specifically Anhui, Fujian, Gansu, Guizhou, Hebei, Heilongjiang, Henan, Hubei, Hunan, Inner Mongolia, Jiangsu, Jiangxi, Jilin, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan, and Zhejiang) and portions of the Russian Far East (up north to the Amur River valley and on Sakhalin Island, and east to Transbaikalia in Siberia), but relatively rare on the Korean Peninsula. Asiatic toads are also found on the Miyako Islands of southern Japan, although they have been extirpated from some islands in recent years, possibly including Okinawa. The Miyako subspecies, ''Bufo gargarizans miyakonis'', is also known as the Miyako toad.

Its natural habitats are subtropical or tropical moist lowland forests, rivers, swamps, freshwater marshes, and intermittent freshwater marshes.

Bufo Eichwaldi
''Bufo eichwaldi'', commonly known as Eichwald's toad or the Talysh toad, is a species of true toads in the family Bufonidae. It was first described by Litvinchuk, Borkin, Skorinov and Rosanov in 2008 and is found in the Talysh and Elburz Mountains in Azerbaijan and parts of northern Iran. It was previously considered to be a subspecies of the Caucasian toad (''Bufo verrucosissimus'').
