wood frogs
Freeze-tolerant forest hoppers
Wood frogs are small North American frogs known for their remarkable freeze tolerance—they survive winter by allowing their bodies to partially freeze, their hearts stopping until spring thaw.
They have a distinctive dark mask across the eyes and breed explosively in temporary woodland pools.
Their duck-like quacking chorus is among the earliest signs of spring in northern forests.
