Gray treefrog

The gray treefrog is a small, climbing frog that makes its home in trees across the eastern U.S. and parts of Canada. Its mottled gray skin helps it blend into bark and lichen like a living camouflage patch.

• Changes color slightly to match its surroundings, from gray to greenish.
• Spends most of its life high in trees, descending only to breed.
• Sticky toe pads let it climb smooth surfaces like glass windows.
