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 (living) 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-li ...

Bufo Bufo
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 ...

Bufotes
''Bufotes'', the Eurasian green toads or Palearctic green toads, is a genus of true toads (family Bufonidae). They are native to Europe (absent from the British Isles, most of Fennoscandia, most of France and the Iberian Peninsula), western and central Asia and northern Africa; a region roughly equalling the western and central Palearctic. Historically they were included in the genus ''Bufo'' and then for a few years placed in ''Pseudepidalea'', which is a synonym of the currently accepted name ''Bufotes''. ''Bufotes'' are typical toads and as suggested by their common names most—but not all— species and individuals have a distinct greenish-spotted pattern. They occur in a wide range of habitats and mostly lay their eggs in fresh water, but sometimes in waters that are brackish. Appearance Size and morphology ''Bufotes'' are fairly small to medium-large toads with adults that are between about in snout–to–vent length. The average size varies significantly depending on ...

True Toad
A true toad is any member of the family Bufonidae, in the order Anura (frogs and toads). This is the only family of anurans in which all members are known as toads, although some may be called frogs (such as harlequin frogs). The bufonids now comprise more than 35 genera, ''Bufo'' being the best known. History Bufonidae is thought to have originated in South America. Some studies date the origin of the group to after the breakup of Gondwana, about 78 - 98 million years ago in the Late Cretaceous. In contrast, other studies have dated the origin of the group to the early Paleocene. The bufonids likely radiated out of South America during the Eocene, with the entire radiation occurring during the Eocene to Oligocene, marking an extremely rapid divergence likely facilitated by the Paleogene's changing climatic conditions. Taxonomy The following phylogeny of most genera in the family is based on Portik and Papenfuss, 2015:, Chan ''et al.'', 2016, Chandramouli ''et al.'', 2016 ...

Cane Toad
The cane toad (''Rhinella marina''), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia. It is a member of the genus ''Rhinella'', which includes many true toad species found throughout Central and South America, but it was formerly assigned to the genus ''Bufo''. The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene in Colombia is indistinguishable from modern cane toads from northern South America. It was discovered in a floodplain deposit, which suggests the ''R. marina'' habitat preferences have long been for open areas. The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs. Its reproductive success is partly because of opportunistic feeding: it has a diet, unusual among anuran ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also 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 (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ...

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 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''). Description ''Bufo eichwaldi'' is a large toad much resembling ''Bufo verrucosissimus'' in appearance. It is a uniform dull brownish grey colour and has large round tubercles on its back and smaller ones on its belly. It differs from ''B. verrucosissimus'' in that the body has different proportions, the head has an abrupt, unrounded snout and the parotoid gland has black markings where it touches the tympanum. The male has dark spots on its otherwise pale belly and is considerably smaller than the female. Distribution and habitat ''Bufo eichwaldi'' is believed to occur in south east Azerbaijan an ...
