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 Stöck 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.
