Frogs do drink water, but not with their mouths.
Like all other amphibians, frogs have naked skin, lacking hair, scales, and feathers, making it perfectly suitable for absorbing water.
Their skin soaks up what they need, then filters it out through their kidneys, like the rest of us.
Some toads don’t even need actual water, they have a specialized patch called a seat in their bottoms that can absorb up to three-quarters of all their water needs while they sit in moist soil.
