Biology: 5 Frogs

4. Amazon Horned Frog



Ceratophrys cornuta is also called the "Amazonian horned frog", "Surinam horned frog" and "Pac-Man-Frog". It is 20 cm long and is found in northern South America. Females are generally larger than males, but males are more ornately colored, ranging from dark green to lime-colored. Females are usually tan.


The frogs eat other frogs, mice and lizards. The tadpoles will eat other tadpoles. Typical ambush predators, they squeeze their bodies into the forest substrate or leaf litter so only their heads protrude. When anything smaller than their own bodies happens by, they spring from the mud and swallow their prey whole, locking it in their jaws with their sharp teeth.

They are aggressively territorial and voracious to fault. Some have been found dead in the wild with the remains of an impossible-to-ingest victim still protruding from their mouths.
