In Alaska, wood frogs freeze for seven months, thaw and hop away
During the cold winters, the Alaskan Wood Frog becomes a frog-shaped block of ice. It stops breathing, and its heart stops beating. When Spring arrives the frog thaws and returns to normal going along its merry way.
The photograph was taken at the Aviarios del Caribe Sloth Sanctuary in Costa Rica. Since 1997, the sanctuary has looked after over 100 orphaned sloths, rearing them until they are ready to return to the wild. The sanctuary also raises awareness about the issues affecting these amazing creatures.
