There’s a frog out there called the Ornate horned frog. They mainly live in Argentina. Even though it doesn’t really have a horn to defend itself, they can cause painful bites. Its scientific name is Ceratophrys Ornata and is in the family Leptodactylidae. Since it is really rotund, you can probably guess why it is also known as “the pac-man frog”.
