Rhinella marina
Cane toad or Marine toad (Rhinella marina)
Description: A large, terrestrial true toad which is native to Central and South America, but has been introduced to various islands throughout Oceania and the Caribbean as well as northern Australia. Adults average 10–15 cm (3.9–5.9 in) in length; the largest recorded specimen weighed 2.65 kg (5.8 lb) with a length of 38 cm (15 in) from snout to vent. The species derives its common name from its use against the cane beetle (Dermolepida albohirtum).
Habitat: The cane toad inhabits open grassland and woodland, and has displayed a "distinct preference" for areas that have been modified by humans, such as gardens and drainage ditches. In their native habitats, the toads can be found in subtropical forests.
Type of sexual reproduction: The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs.
Eating habits: Its reproductive success is partly because of opportunistic feeding: it has a diet, unusual among anurans, of both dead and living matter. Most frogs identify prey by movement, and vision appears to be the primary method by which the cane toad detects prey; however, the cane toad can also locate food using its sense of smell. They eat a wide range of material; in addition to the normal prey of small rodents, reptiles, other amphibians, birds and a range of invertebrates, they also eat plants, dog food and household refuse.
Diseases and harm to humans: The cane toad has poison glands, and the tadpoles are highly toxic to most animals (including livestock) if ingested. There have even been human deaths due to the consumption of cane toads. The cane toad is now considered a pest and an invasive species in many of its introduced regions; of particular concern is its toxic skin, which kills many animals—native predators and otherwise—when ingested. This is a big problem in areas where it has been introduced as local animals are not aware of the danger it poses them.
Prevention: Because of its voracious appetite, the cane toad has been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control. The cane toad does have its uses including in drugs, as leather, and for scientific research. Florida Fish and Wildlife Conservation Commission recommends residents kill them.
