Budgett’s Frogs

(Lepidobatrachus laevis) are some of the most unusual and charismatic amphibians out there.

General Overview

  • Scientific name: Lepidobatrachus laevis

  • Common names: Budgett’s frog, Paraguay horned frog, hippo frog

  • Native range: Paraguay, Argentina, Bolivia

  • Lifespan: Around 7–10 years in captivity (sometimes longer)

  • Size: 4–5 inches long, but with very wide, flattened bodies

Appearance

  • Flattened, broad head that makes up about half of their body length

  • Wide, comical grin with tiny sharp teeth

  • Short, stubby legs adapted for lunging and grabbing prey rather than hopping

  • Skin color is usually olive-green to brown, often with darker mottling for camouflage

Behavior & Natural History

  • Aquatic lifestyle: They spend much of their time in shallow, stagnant pools or slow-moving water.

  • Sit-and-wait predators: Like Pacman frogs, they are ambush hunters—waiting motionless until prey comes near.

  • Diet: Opportunistic feeders that eat insects, worms, fish, smaller frogs, and even their own kind.

  • Defense: If threatened, they make a loud squeak and inflate their bodies. They also bite and hold on tightly.

  • Estivation: In the dry season, they burrow into mud and form a protective cocoon, waiting for rain to return.

Captive Care Highlights

  • Enclosure: A semi-aquatic setup works best—half water, half land area with easy access between.

  • Temperature: 75–80°F with slightly cooler nights.

  • Humidity: High, since they are aquatic frogs.

  • Feeding: Mostly insects and worms; occasional fish or amphibian-safe protein. They are aggressive feeders and will try to swallow prey nearly as large as themselves.

  • Handling: Best avoided—like Pacman frogs, their skin is sensitive, and they can bite.

Conservation & Fun Facts

  • Not currently endangered, but populations depend on wetland habitats that are vulnerable to climate change and human activity.

  • Their tadpoles are unusual—they are predatory from the start, feeding on other tadpoles.

  • Because of their strange appearance and behaviors, they’re a favorite among exotic amphibian enthusiasts.
