Bufo is a large genus of about 150 species of true toads in the amphibian family Bufonidae. Bufo is a Latin word for toad.
Contents
Description
True toads have in common a stocky figure and short legs, which make them relatively poor jumpers. As with all members of the family Bufonidae, they lack a tail and teeth, and they have horizontal pupils. Their dry skin is thick and warty.
Behind their eyes, Bufo species have wartlike structures, the parotoid glands. These glands distinguish the true toads from all other tailless amphibians. They secrete a fatty, white poisonous substance which acts as a deterrent to predators. Ordinary handling of toads is not dangerous, and does not cause warts in contradiction to folk beliefs. The poison of most if not all toads contains bufotoxin; the poison of the Sonoran Desert Toad, Bufo alvarius, is a potent hallucinogen containing 5-MeO-DMT and bufotenin. The poison's psychoactive effects are said to have been known to Precolumbian Native Americans.[citation needed]
Toads can also inflate their bodies when threatened. Males are usually smaller than females and possess the organ of Bidder, an incomplete ovary. The adult males of many species show a dark throat. Breeding males have dark nuptial pads on their thumbs.[1] When stressed, toads can let a poison seep through their skin that when swallowed could kill a large dog.
Distribution
This is a truly cosmopolitan genus, able to live under adverse conditions, and occurring around the world except in the Arctic and Antarctic, Madagascar, Australia (with the exception of the introduced Cane Toad), and New Guinea and Oceania.
Bufo species in the British Isles
Two species are found in the British Isles: the Common Toad (Bufo bufo), and the Natterjack Toad, (Bufo calamita). The former is found almost everywhere. The Natterjack, which differs in its shorter limbs with nearly free toes (which are so short that the toad never hops but proceeds in a running gait) and in usually possessing orange or red warts, green eyes and a pale yellow line along the middle of the back, is local in England, the south-west of Scotland, and the west of Ireland. It is further remarkable for the very loud croak of the males, produced by a large vocal bladder on the throat which, when inflated, is larger than the head.
Psychoactive properties
There are several species of Bufo toads which produce poison that has psychoactive properties. The poison of one species (Bufo alvarius) contains both 5-MeO-DMT and bufotenin, while some others contain only bufotenin.[2] Author Lee B. Croft, in his satiric novel, Toadies: The Explanation of Toxicomania in American Society, has coined the word "bufoglossation" to describe the deliberate licking of Bufo toads for hallucinogenic purposes,[3] but psychoactive substance information site Erowid warns against such use because of the cardiotoxins included in the toads' venom[4].
Groups
Species in this genus can be quite different, which has led to a recent recommendation in the Bulletin of the American Museum of Natural History to split the genus, a recommendation that has been rejected (in part) by many taxonomists (see Pauly et al., 2004, Evolution 58: 2517–2535; Pauly et al., 2009, Herpetologica 65:115-128). Instead, the relationships between the different species are formalized by categorizing them into subgenera, such as Anaxyrus and Rhinella.
Species
Bufo is a large group, and it is usually divided into several subgenera. Frost et al. (2006) removed most of the species of former Bufo to other genera and restricted the name Bufo to members of the Bufo bufo group of earlier authors. However, other authors continue to recognize these subgroups of Bufo as subgenera.[5]
Rhinella is composed of a combination of Rhamphophryne and Chaunus (two subgroups of Bufo in the broad sense). Rhinella is recognized as a distinct genus by some, although other herpetologists disagree and maintain these species as a subgenus within Bufo. Here the species of Rhinella are treated in a separate page (where they may be considered a separate genus or as a subgenus of Bufo).
Subgenus Anaxyrus
Main article: AnaxyrusContains 22 species found in North and Central America including the common American Toad, Bufo americanus. See separate article.
Subgenus Bufo
Composed of 12 species. Found in Temperate Eurasia and Japan south to North Africa, the Middle East, northeastern Myanmar and northern Vietnam.

An assemblage of 25 species which remained outside the main groups. Frost et al. denoted the species in this group as polyphyletic by placing "Bufo" in quotation marks. Presumably, as these taxa are studied they will be allocated to one or another of the existing groups.
