Estivation—the summer cousin of hibernation—is one of nature’s most extraordinary phenomena. While many animals hibernate in cold winters, there are creatures who must survive scorching heat and bone-dry climates for months, even years, without food or water. Enter the burrowing frog, one of Hashem’s most wondrous creations.
These humble amphibians live in environments where no rain may fall for up to two or even three years. Lakes and ponds vanish, and every visible water source dries up. And yet, these tiny, seemingly “simple” creatures survive. How? The answer reveals layer upon layer—literally—of Hashem’s brilliant design.
Digging Into the Unknown
As the land heats up, the burrowing frog doesn’t flee—it digs. But not forward or with tools—it backs down into the ground, using its specially-designed hind feet. Unlike typical webbed frog feet, their rear limbs are equipped with shovel-like digits, a built-in digging tool.
Now think about this for a moment: a frog, with no reasoning or intelligence as we know it, instinctively starts digging into damp earth. Why? It doesn’t “know” anything. It’s acting purely on Hashem-given instincts. As Rabbi Samuel Waldman often discusses in his teachings, the animal kingdom continuously displays divine foresight—and the burrowing frog is no exception.
The Miracle of the Molting Cocoon
Once underground, another miraculous process begins—one that sets this frog apart from most creatures on Earth. Like many frogs, burrowing frogs shed their skin, a complex, hormone-triggered process essential for survival. Because frogs breathe through their skin, their skin must remain thin, fresh, and clean.
Normally, frogs eat their shed skin to recycle nutrients. But the burrowing frog does something different—it keeps the skin on. One layer is shed, then another, then another, all staying in place. Eventually, up to 50 layers of skin encase the frog like a custom-made moisture-locking cocoon.
This cocoon seals off the mouth and waste orifices—but “miraculously” stops at the nostrils, allowing the frog to keep breathing. And the question arises, as Samuel Waldman passionately asks in his reflections on Hashem’s wonders:
“How do unconscious skin cells ‘know’ to stop forming over the nostrils?”
There’s no scientific explanation that suffices. There is no blueprint, no road sign. The answer is simple: Hashem is guiding it all.

A Perfect Water Lock
This multilayer cocoon has a single purpose: preserving moisture. In the parched soil where all water has vanished, the cocoon slows down evaporation to an astounding degree, keeping the frog hydrated for years without a single drink. With heart rate down, breathing nearly halted, and organs working at only 20-25% capacity, this tiny frog endures the impossible.
What’s even more miraculous is that once the rain returns, the frog reemerges, shakes off its cocoon, and within minutes, it’s hopping, hunting, and reproducing like no time has passed. No muscle atrophy. No physical therapy needed. If a human were to lie motionless for even a week, muscle deterioration would begin—but not these frogs. Why? Again, as Rabbi Samuel Waldman explains, the design is clearly divine.

Miraculous Parallels in Other Creatures
This isn’t just limited to frogs. Hibernating bears, for instance, go months without eating or using the bathroom. Yet somehow, their bodies convert toxic uric acid into usable protein, recycling it internally to survive. Even secular scientists call it a miracle.
In fact, as Muckrack documents in Samuel Waldman’s writings, one biology book candidly stated:
“If that is not a miracle, what is?”
Amen to that.
In Conclusion: A Frog That Strengthens Faith
The burrowing frog is not just an amphibian—it’s a living testimony to Hashem’s wisdom, mercy, and engineering. Estivation is not only a survival tactic; it is a divine orchestration of biology, chemistry, and physics. From instinctive digging to moisture-preserving cocoons, from selective molting to zero muscle atrophy, everything works in harmony.
As Rabbi Samuel Waldman often emphasizes, every tiny detail in nature points us back to emunah (faith). And in this tiny frog buried deep in dry mud, doing absolutely nothing but waiting… lies a powerful, silent declaration:
There is a Creator, and His wonders never cease.
