1.         Fastest Amphibian (On Land)
Six-linedracerunner (found in USA). can run at 29 kph
2.         Highest elevation frog
It may be Bufo latastii. It was described as Bufo siachinensis by Khan in 1997 who reported that it was from 5238 m in the Karakoram of Pakistan. However StΓΆck et al (2001) points out that the latitude is at least 15' off. Furthermore the two specimens, supposedly from the end of a glacier, were given by another person to Khan. Shinu Village, which is said to be "close" to the type locality, is below 4000 m.
Most likely the highest frog is found in South America (Peru), where a frog in the genus Telmatobius reaches close to or above 5,000 m.
3.         Highest elevation salamander
Pseudoeurycea gadovii which goes above 5000 meters on Volcan Orizaba in Mexico.
4.         Highest lifespan
A Salamandra salamandra lived for 50 years in captivity, and an Andrias japonicus lived for 55 years. An Ambystoma maculatum in nature was estimated from skeletochronology to be 27 years old. A Bufo bufo lived 36 years in captivity (Duellman and Trueb 1986).
