wood frog
Ice-surviving forest hopper
A wood frog is a North American frog that lives in forests and is remarkable for surviving being frozen solid during winter.
Its body produces natural antifreeze, allowing it to thaw and resume activity in spring.
Wood frogs are brown with a distinctive dark mask across the eyes: We found a wood frog under the leaf litter.
