Budgett's Frog

Lepidobatrachus laevis

Also known as Hippo Frog, Freddy Krueger Frog, Escuerzo de Agua, Wide-mouthed Frog

Budgett's frogs are highly aquatic ambush predators native to the seasonal wetlands of the Gran Chaco region in South America. Equipped with an enormous, flattened head and wide mouth lined with sharp odontoid projections, they sit submerged in shallow, muddy water waiting to swallow prey whole. When seasonal pools dry up, they burrow into the mud and secrete multiple layers of shed skin to form a waterproof cocoon, estivating for months until the rains return.

  3. High
  4. Very high
Why interaction risk is low
Inflates, hisses, and delivers a painful bite with sharp jaw ridges if cornered; observe without handling.
Why it is dangerous
Possesses prominent, pointed bony ridges (odontoids) in the lower jaw that can easily puncture skin and draw blood during a defensive strike.
How to recognize a risky encounter
Look for a remarkably flattened, rounded body, eyes set high on top of the head, and an expansive mouth stretching nearly the full width of the skull.
What to do
Do not attempt to catch or hold wild individuals; give them space if they puff up, stand on outstretched legs, and emit a high-pitched scream.
Responsible observation
  • Observe undisturbed: Watch from the edge of ephemeral ponds without stepping in murky shallows.
  • Avoid handling: Stressed individuals shriek loudly and lunge forward to bite defensively.
