Behavior and toxicity

Cane toads are mostly active at night and are not shy of human settlements, often gathering under lights to catch insects. Their main defense is bufotoxin, a potent poison stored in the large parotoid glands behind the eyes. Predators that bite or swallow a cane toad can be sickened or killed, which is why the species is so damaging where native animals have no resistance.

Diet and feeding

Unusually for amphibians, cane toads are opportunistic omnivores. They eat beetles, ants, and other insects, but also small reptiles, frogs, rodents, and even pet food or kitchen scraps. This flexible diet helps them thrive in disturbed and human-modified habitats.

Habitat and range

The cane toad is native to the southern United States, Central America, and northern South America. It was deliberately introduced to many regions, most infamously to Australia in 1935 to control sugarcane beetles. There it spread rapidly and became one of the country's worst invasive species.

Conservation

In its native range the cane toad is listed as Least Concern and is not threatened. The conservation concern is the opposite: where it has been introduced, it poisons native predators and disrupts ecosystems. Management focuses on limiting its spread and protecting vulnerable native wildlife.

Did you know? Cane Toad facts

• The cane toad is a large, warty terrestrial toad native to the Americas, reaching up to 1 kg (2.2 lb).
• Yes. Cane toads secrete a powerful toxin called bufotoxin from glands behind their eyes. It can sicken or kill predators and pets that bite or swallow the toad.
• Cane toads were introduced to Australia in 1935 to control crop pests but instead spread widely. Their toxin kills native predators that have no resistance, making them one of Australia's most damaging invasive species.
• Cane toads are omnivores. They eat insects such as beetles and ants, as well as small reptiles, frogs, rodents, and even pet food or scraps.
• Cane toads commonly reach 10 to 15 cm (4 to 6 in) and can weigh up to about 1 kg (2.2 lb), making them one of the largest toads in the world.
• Conservation: Least Concern (IUCN).

Diet & feeding

Cane Toad feeds primarily as a omnivore (insects, small animals, scraps). Unusually for amphibians, cane toads are opportunistic omnivores. They eat beetles, ants, and other insects, but also small reptiles, frogs, rodents, and even pet food or kitchen scraps. This flexible diet helps them thrive in disturbed and human

Communication

• Cane Toad uses scent, posture, and vocal signals to mark territory and coordinate social behaviour.
• Communication intensity often peaks during breeding seasons and territorial disputes.
