1. Cane Toad – Bufo marinus
The cane toad is widely introduced in many countries around the world and is used as a biological control agent against pests that harm sugarcane. Currently, the cane toad has become a pest in the areas where it has been introduced. Cane toads are voracious eaters and consume all types of organisms they can find. They also hunt and compete for food and breeding grounds with native amphibian species.
Common names: cane toad, giant toad, marine toad.

The coqui frog is a small, noisy, insectivorous frog native to Puerto Rico, where they breed and can have densities of up to 20,000 individuals per hectare. They have adapted and thrived in Hawaii and the Virgin Islands. In Hawaii, they are considered both an urban pest and a potential threat to native forest bird species.
3. Bullfrog – Rana catesbeiana
Bullfrogs have spread to many countries due to the commercial trade of seafood and ornamental fish. They are often traded and raised for their meat in various parts of the world. The main issue is that in the wild, they have a high adaptability, strong competition, and consume native reptile species.
