The body of the Siberian salamander survives extreme cold temperatures via 'antifreeze' chemicals.


“Some urodeles can tolerate very low ambient temperatures: the most impressive example is probably the Siberian salamander, Salamandrella keyserlingii, which can survive for prolonged periods at -45° C.” (Fowler and Miller 2003:33-34)

“Sudden frost is a serious problem for the Siberian salamander. It needs time to adapt to the cold and produce the ‘antifreeze’ chemicals that replace water in blood and cells and protect tissues from damage by sharp ice crystals. Some animals use glucose, glycerol and related compounds to protect them from freezing in this way. The exact mechanism in the Siberian salamander is not known.” (Potapov 1993:15)
