8 Amphibian Species Disappearing from American Wetlands (And 8 That Are Surprisingly Resilient)

8 Amphibian Species Disappearing from American Wetlands (And 8 That Are Surprisingly Resilient)

They’re vanishing before we even get to know them.

Tiny frogs, slippery salamanders, creatures that once filled wetlands with croaks and splashes—some are fading like mist in morning sun.

Pollution. Drought. Disease. Bulldozers. The reasons pile up, but the result is the same: a silence creeping across America’s swamps, ponds, and marshes where life used to sing.

But not all hope is lost.

While some amphibians are fighting a losing battle, others are proving maddeningly tough. Clinging on. Rebounding. Outwitting everything we’ve thrown at them.

This is a story of two paths—disappearance and defiance.
Of ghost calls in the night, and of survivors with muddy feet.

Let’s meet the 8 amphibian species that need urgent help—
And 8 more that refuse to go down quietly.
