The Surinam toad or star-fingered toad is a species of frog in the Pipidae family. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Trinidad and Tobago, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, swamps, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss.Its feet are broadly webbed with the front toes having small, star-like appendages. Specimens of close to 20 cm (8 in) in length have been recorded, although 10-13 cm (4-5 in) is a typical size. The Surinam toad has minute eyes, no teeth and no tongue.
The Malayan Horned Frog
The Long-nosed Horned Frog also known as the Malayan Horned Frog or Malayan Leaf Frog is a species of frog restricted to the rainforest areas of southern Thailand and Peninsular Malaysia to Singapore, Sumatra and Borneo. This species is a large frog ranging from 100-120 mm in length. They are light to dark brown on the dorsal surface with varying patterns and camouflage very well with the forest floor. The throat is black-dark brown and diffuses into cream-yellow halfway along the ventral surface. The upper eyelids and snout are drawn out into long triangular projections, forming what looks like “horns”, giving them their common name.
The Purple Frog
It can be found in the Western Ghats in India. Names in English that have been used for this species are purple frog, Indian purple frog or pignose frog. The body of Nasikabatrachus sahyadrensis appears robust and bloated and is relatively rounded compared to other more dorsoventrally-flattened frogs. Its arms and legs splay out in the standard anuran body form. Compared to other frogs, N. sahyadrensis has a small head and an unusual, pointed snout. Adults are typically dark purplish-grey in color. Males are about a third of the length of females.
The Crucifix Toad
The Crucifix Toad is the most distinctive species of frog within the Notaden genus. Whereas most Notaden frogs are dark brown in colour, the Crucifix Toad exhibits many bright colours. Its dorsal surface is bright yellow, with a cross of many colours centered on the back. The cross is outlined with large, black dots, and filled with white, black and red dots. The ventral surface is white, and the flank’s blue. The Crucifix Toad is a small, and very round frog. Its nose is blunt, and legs and feet are small. As this species is fossorial, the tympanum is hidden. Males reach a length of 6.3 centimetres (2.5 in), and females a length of 6.8 centimetres (2.7 in). The species feet have little “spades” to help them burrow deeply.
Atelopus, commonly known as Harlequin toads, is a large genus of true toads from Central and South America, ranging as far north as Costa Rica and as far south as Bolivia. Atelopus are small, generally brightly colored and diurnal. Most species are associated with mid- to high-elevation streams. This genus has been greatly affected by amphibian declines, and many species are now considered endangered, while others already are extinct. The cause of these declines primarily appears to be the chytrid fungus Batrachochytrium dendrobatidis.
