They are relatively short with high dorsal fins which have darker pigments speckled on them. Usually in late June through August. The process begins about 45-60 days after hatching. Peepers actually complete metamorphosis on land near the ponds, so they still have tails when they leave the water. Spring Peepers overwinter in shallow soil, and the water in their bodies actually freezes.
Peepers use glucose like antifreeze to protect their cells from damage.
