Cane toads have become an ecological disaster in Australia, and other places to which they have been introduced. They eat the native wildlife, but have no natural predators. Cane toads eat native frog species, as well as other small birds and mammals, and they compete directly with native frogs and other species for food. Many native frog species are at risk of extinction as a result of the cane toad population.
The only animals that have worked out how to eat them safely are crows, which flip the toads over and eat the soft underbelly, where there are no poison glands. Northern quolls have suffered huge population losses because habitat loss and the resultant drop in food sources has driven them to try to eat the cane toad, which has, of course, poisoned these mammals. Any native animal that normally eats frogs will be poisoned by the cane toad.
Cane toads are also continuing to spread south. They are remarkably adaptable creatures, and seem to be becoming hardier, adapting to a wide variety of habitats and climate conditions. They also breed prolifically, and wherever they populate, they push out the native species.
cane toads are here because in 1932 the sugar cane authorites had a problem with cane grub which was destroying there crops. so they had a meeting and found the only way to get rid of them was to introuce the cane toad. so then they brought 102 cane toads from Hawaii to get rid of the problem.
The cane toad is native to Central and South America and has a voracious appetite for certain pests that harm sugarcane crops. For this reason, it was introduced as pest control in the Caribbean and Pacific with great success. Thus, Australian sugarcane plantations decided to use cane toads to control their pests. However, cane toads are fatally poisonous, and thus no predators can control their populations. Thus, they have become dangerously prolific and invasive.
Interesting note: Some crows in Australia have figured out how to eat cane toads while avoiding their poison glands. Yay crows! :)
They are big and eat a lot so they make other species of frogs and toads compete for the food supply.

The cane toads were originally introduced to control the population of a beetle, but they breed and reproduce extremely quickly, with over 30,000 eggs per brood, so the cane toad population exploded. Because they are also poisonous, they have no natural predators, meaning their population is still dramatically increasing. Scientists are yet to come up with a solution to control their population growth.
I hope this is helpful! :D
Cane toads have few natural enemies and can kill any small creature that bites them with the toxin in their glands.
There are so many cane toads today because they're prolific breeders, which means they breed very fast and the time span they are pregnant for isn't very long. :)

What native animal eats cane toads?
The cane toad is a poisonous creature. There are some native animals that are able to eat a cane toad while avoiding the poison, however. These animals include keelback snakes and saw-shelled turtles.
What toad has been a pest in Australia?
The cane toad was introduced into Australia. Australia has no native toads at all.
Why didn't cane toads take over Hawaii?
cane toads eat all native species like insects and snake eat cane toads but then the snake will die from the poison inside the cane toad and might lead into exiction
Are baby cane toads poinonous for dogs?
Yes. At all stages of the cane toad's life cycle, from eggs to tadpoles to baby toads to adults, cane toads are poisonous to anything that tried to ingest them. The poison has been responsible for the deaths of many native Australian animals.
What eats cane toads and how are they affected?
Not many animals eat cane toads because of their warts and their repulsive appearance. The few creatures that eat toads include snakes, and owls. However, cane toads are frequently run over and squashed on the roads.
Why were cane toads brought to Queensland?
Native to Central and South America, Cane toads were introduced to Australia from Hawaii in June 1935 by the Bureau of Sugar Experiment Stations in an attempt to control the native cane beetle (Dermolepida albohirtum). These beetles are native to Australia and they are detrimental to sugar cane crops, which are a major source of income for Australia.
What impact do cane toads have on Quolls?
Cane toads have had a major impact on quoll populations in Queensland and the Northern Territory. Quolls are carnivores, and feed on birds, reptiles, arthropods and mammals up to the size of a possum. Habitat loss has resulted in fewer of these species and thus a reduced food source for the quolls, so they have resorted to eating cane toads. Spotted-tail and Northern Quolls are both being killed off as a result of eating the Cane Toad, which is poisonous.
What was to control cane beetles in 1935?
cane toads
Do cane toads have gills?
cane toads have lungs
What damage did cane toads do to Australia?
Cane toads eat anything thay can handle (eat) and have no natural enemies. They also eat rare species of other frogs for example. The toads are poisonous so Australian enemies that will attempt to eat the toad will die, including pets like cats and dogs.
What is a cane frog?
Cane frog or cane toad also known as the Giant Neotropical Toad or Marine Toad, is a large, terrestrial true toad native to Central and South America. Cane toads are a serious conservation issue in Australia. As their populations increase, they threaten the existence of many natural animals. Cane toads are tough and adaptable, as well as being poisonous throughout their life cycle, and have few predators in Australia.
Names of animals that have been introduced that threaten survival of native animals?
Feral pigs and cats, cane toads, rabbits (Australia)Grey squirrels are having a bad affect on the red ones and the mink is threatening a lot of native water fowl.
