(PhysOrg.com) -- Scientists have long been intrigued by the longevity of a tiny amphibian known as the blind salamander, but it now seems it may live a long time because it basically has no life.
Scientists scouring the mountains of Borneo spotted a toad species last seen in 1924 by European explorers and provided the world with the first photographs of the colorful, spindly legged creature, a researcher said Thursday.

Order Temnospondyli - extinct Subclass Lepospondyli - extinct Subclass Lissamphibia Order Anura Order Caudata Order Gymnophiona
Amphibians (class Amphibia), such as frogs, toads, salamanders, newts, and caecilians, are ectothermic (or cold-blooded) animals that metamorphose from a juvenile water-breathing form, to an adult air-breathing form. Though amphibians typically have four limbs, the Caecilians are notable for being limbless. Unlike other land animals (amniotes), amphibians lay eggs in water. Amphibians are superficially similar to reptiles.
Amphibians are ecological indicators, and in recent decades there has been a dramatic decline in amphibian populations around the globe. Many species are now threatened or extinct.
Amphibians evolved in the Devonian Period and were top predators in the Carboniferous and Permian Periods, but many lineages were wiped out during the Permian-Triassic extinction. One group, the metoposaurs, remained important predators during the Triassic, but as the world became drier during the Early Jurassic they died out, leaving a handful of relict temnospondyls like Koolasuchus and the modern orders of Lissamphibia.
