The cane toad, 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.
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. Some of the genera that contain species formerly placed in Bufo are Anaxyrus, Bufotes, Duttaphrynus, Epidalea and Rhinella.
The common toad, European toad, or in Anglophone parts of Europe, simply the toad, is a frog found throughout most of Europe, 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.
The Colorado River toad, also known as the Sonoran Desert toad, is a toad species found in northwestern Mexico and the southwestern United States. It is well known for its ability to exude toxins from glands within its skin that have psychoactive properties.
The Houston toad, formerly Bufo houstonensis, is an endangered species of amphibian that is endemic to Texas in the United States. This toad was discovered in the late 1940s and named in 1953. It was among the first amphibians added to the United States List of Endangered Native Fish and Wildlife and is currently protected by the Endangered Species Act of 1973 as an endangered species. The Houston toad was placed as "endangered" on the IUCN Red List of Threatened Species from 1986 to 2022, and has worsened to "critically endangered" since then, with fewer than 250 mature individuals believed to remain in the wild as of 2021. Their kind is threatened every day as they continue to suffer from a loss of habitat, extreme drought, and massive wildfires. Their typical life expectancy is at least 3 years but it may exceed this number.
The western toad is a large toad species, between 5.6 and 13 cm long, native to western North America. A. boreas is frequently encountered during the wet season on roads, or near water at other times. It can jump a considerable distance for a toad. Breeding occurs between March and July in mountainous areas, and as early as January in lower-elevation regions. The female lays up to 17,000 eggs stuck together in strings that adhere to vegetation and other objects along water edges.
The arroyo toad is a species of true toads in the family Bufonidae, endemic to California, U.S. and Baja California state, Mexico. It is currently classified as an Endangered species on the IUCN Red List of Threatened Species because of habitat destruction. The arroyo toad is at the intersection of ecological significance and conservation concern.
The red-spotted toad, formerly Bufo punctatus, is a toad in the family Bufonidae found in the southwestern United States and northwestern Mexico.
The southern toad is a true toad native to the southeastern United States, from eastern Louisiana and southeastern Virginia south to Florida. It often lives in areas with sandy soils. It is nocturnal and spends the day in a burrow. Its coloring is usually brown but can be red, gray, or black. It is approximately 8 cm (3 inches) long.
Woodhouse's toad is a medium-sized true toad native to the United States and Mexico. There are three recognized subspecies. A. woodhousii tends to hybridize with Anaxyrus americanus where their ranges overlap.
The boreal toad is the nominate subspecies of the western toad. They are commonly found in the Southern Rocky Mountains, and their population has recently been on the decline due to an emerging amphibian disease, chytrid fungus. The boreal toad is currently listed as an endangered species by Colorado and New Mexico. It is known in Colorado as the only alpine species of toad.
Fowler's toad is a species of toad in the family Bufonidae. The species is native to North America, where it occurs in much of the eastern United States and parts of adjacent Canada. It was previously considered a subspecies of Woodhouse's toad.
The Canadian toad, also known commonly as the Dakota toad, is a species of toad that ranges from the prairie regions of western Canada south to parts of the upper midwest of the United States. It belongs to the family Bufonidae, the "true" toads. Its specific name is derived from the Latin word hemiophrys, meaning eyebrow, which refers to its pronounced cranial crest between and behind the eyes. Anaxyrus hemiophrys displays the typical toad characteristics: it lacks a tail and teeth, it has a horizontal pupil, and its dry skin is thick and warty.
The Rocky Mountain toad or western Woodhouse's toad is a subspecies in the Woodhouse's toad subgroup. It can be identified by its light middorsal stripe, prominent cranial crests, and elongate parotoid glands. The belly is usually white or yellowish with dark flecks between the forelegs
The Yosemite toad is a species of true toad in the family Bufonidae. Endemic to the Sierra Nevada of California, the species ranges from the Alpine County to Fresno County. Yosemite toads are only found in the montane to subalpine elevational zone of 1,950–3,445 m (6,398–11,302 ft) asl. The Yosemite toad is similar to the nearby western toad, but in many ways adapted to a high elevation lifestyle. It was initially described during the Grinnell Survey of California, by an undergraduate student of Joseph Grinnell named Charles Camp.
Rhinella jimi is a species of toads in the family Bufonidae. It is endemic to northeastern Brazil and known between Bujaru in northeastern Pará and Maranhão in the north, south to Bahia and Vitória, Espírito Santo. Prior to its description in 2002, it was confused with Rhinella schneideri. The specific name jimi honors Jorge Jim, a Brazilian herpetologist. Common name Jimi's toad has been coined for it.
The Arizona toad is a species of toad in the family Bufonidae. It is endemic to the south-western United States, where its natural habitats are temperate lowland forests, rivers and streams, swamps, freshwater marshes, freshwater springs, ponds, open excavations, irrigated land, and seasonally flooded agricultural land.
The oak toad is a species of toad in the family Bufonidae. It is endemic to the coastal regions of southeastern United States. It is regarded as the smallest species of toad in North America, with a length of 19 to 33 mm.
Bufotes, the Eurasian green toads or Palearctic green toads, is a genus of true toads. They are native to Europe, 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.
The Hot Creek toad is a species of toad in the family Bufonidae. It is endemic to Nye County in the state of Nevada in the United States.
