Is it true that frogs can survive being frozen and thawed?
Unclear. Peer-reviewed studies and reference works show that a small number of frog species, notably the wood frog and Cope's gray treefrog, tolerate whole-body freezing and thawing. None of the placed sources establishes that frogs generally can survive being frozen and thawed.
