It's time for #MarshMadness!
This picture was taken not in a marsh, but in the Roman ruins at Al-Bass in Sour (Tyre), Lebanon. The frog is, however, a marsh frog (Rana ridibunda), so I think it counts.
At the risk of injecting a political note into a celebration of all things marshy, Al-Bass is adjacent to a Palestinian refugee camp that has been repeatedly bombed or shelled by Israeli forces, most recently in 2024.
