‘Incilius periglenes,’ a brilliant orange frog with tubercular skin; photo by Charles H. Smith - U.S. Fish and Wildlife Service ‘Pseudophilautus_variabilis,’ a 1.5 inch frog with indistinct stripes from head to haunches ‘Atelopus vogli,’ an dead orange toad tied about the waist with a string from a tag, from Montalbán (Estado Carabobo, Venezuela) ‘Hypselotriton wolterstorffi,’ male and female, a black newt with orange stripes, from Boulanger ‘Rheobatrachus silus,’ a medium-sized frog with gray skin and darker blotches, protruding eyes, blunt snout, long unwebbed fingers, webbed toes, and large arms and legs covered with mucus ‘Taudactylus diurnus,’ a mottled light-brown and darker reddish-brown frog ‘Nannophrys guentheri,’ a small frog with a short rounded snout, long toes, tubercular skin above, smooth skin below


The newt is a salamander, but not all salamanders are newts. All salamanders have splayed legs, blunt snouts, tails, and permeable skin. The newt is semiterrestrial and semiaquatic. * The toad likes dry; the frog likes wet. Mother toad lays eyes in long chains; mother frog lays eggs in clusters. The toad has shorter legs and poison glands behind its eyes. The frog has vomerine teeth; of which the toad has none.

Golden toad

This little toad occupied moist burrows in the elfin cloud forest and laid its eggs in rainwater pools among tree roots in the spring. Once abundant in a small area north of Monteverde, Costa Rica, the golden toad was discovered in 1964 and disappeared in 1989.

Shrub frog

Thirteen species of tree frogs of southwestern India and Sri Lanka are known to be extinct. Pseudophilautus variabilis, for example, has not been found since 1858, probably eliminated from urbanization and disease.

Harlequin toad

This diurnal harlequin toad also known as Vogl’s stubfoot toad was last seen alive in 1957. It was defenseless against rising temperatures and habitat destruction by mining, deforestation, and urbanization. Its bright orange color did not ward off amphibian chytrid fungus.

Yunnan Lake newt

Found only near the Kunming Lake in Yunnan, China, thus brightly colored newt with its orange stripes and spots has not been seen alive since 1979.

Southern gastric-brooding frog

This medium-sized frog, a.k.a. the platypus frog, once living in rainforest creeks in one small areas in Australia, with protruding eyes and blunt snout, incubated its offspring in the mother’s stomach. “Weeks after ingestion, juvenile frogs escape through the mother’s mouth.”

Mount Glorious day frog

Day frog or torrent frog, once living in montane rain forests in southwest Queensland, Australia, eating small invertebrates along streams and from the forest floor, was probably finished off by feral pigs that ate them and muddied their streams.

Günther’s streamlined frog

Found in Sri Lanka, exact location unknown and poorly preserved, little is known of this small frog and little more can be added now.
