The Cane Toad is very common in Costa Rica. The nocturnal amphib is the world's largest toad and can grow up to 25 cm and weigh more than a kilo.
The skin of this toad is toxic to many animals, it can kill a dog and even a human. If threatened, it produces poison to humid its body and it can even shoot its toxin at a distance. Additionally it can inflate its body to appear larger to a predator.
The cane toad is a prolific breeder. A female lays 8,000–25,000 eggs at once in a string that can stretch up to 20 meters. Even the eggs and tadpoles of these toads are toxic to many animals.

The giant toad is native to South and Central America but has been introduced in many other parts of the world to combat pests like the cane beetle. It has however become a pest in many of its new homes.
In Costa Rica the cane toad can be helpful to reduce insect populations. The opportunistic animal has well adapted to human homes and with its immense appetite devors all kind of bugs, as itchy, toxic, biting it may be.
