The common toad reaches maturity at three to seven years old but there is great variability between populations. [15] Juveniles are often parasitised by the lung nematode Rhabdias bufonis. This slows growth rates and reduces stamina and fitness. Larger juveniles at metamorphosis always outgrow smaller ones that have been reared in more crowded ...
The eastern American toad (A. a. americanus) is a medium-sized toad usually ranging in size from 5–9 cm (2.0–3.5 in); [13] the record length for an eastern American toad is 11.1 cm (4.4 in). [14] The color and pattern is somewhat variable, especially for the females.
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. [ 1 ] [ 2 ] In popular culture ( folk taxonomy ), toads are associated with drier, rougher skin and more terrestrial habitats. [ 3 ]
The Surinam toad, despite its common name, is actually native to several South American countries; as well as Suriname, it is known from Brazil (primarily the states of Acre, Amazonas, Mato Grosso, Pará and Rondônia), Bolivia, Colombia, Ecuador, French Guiana, Guyana, and Venezuela, in tropical rainforest regions to the east of the Andes.

Woodhouse's toad is a robust amphibian and can grow to a maximum snout-vent length of 127 mm (5 in). The head has prominent cranial crests in front of and in between the eyes. The parotoid glands are long and large. The dorsal surface of this toad is grayish-brown or yellowish-brown and it is speckled with small dark spots.
The toad was eventually passed on to the Booth Museum of Natural History in Brighton via Henry Willett. However, the toad has since shrunk, suggesting that it cannot have been very old at the time of its discovery. [15] [16]
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 fire-bellied toads are a group of six species of small frogs (most species typically no longer than 1.6 in or 4.1 cm) belonging to the genus Bombina.. The name "fire-bellied" is derived from the brightly colored red- or yellow-and-black patterns on the toads' ventral regions, which act as aposematic coloration, a warning to predators of the toads' reputedly foul taste.
