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.
Where can a cane toad frog be found today?
all over north eastern Australia and spreading Carribbean islands, Hawaii and Australia.
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.
Why are cane toads a problem for native animals?
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.
Why did cane toads come to Australia?
Cane toads were imported by the Australian Bureau of Sugar Experimental Stations to eat cane beetles. The beetles were a major pest of sugar cane and threatened to ruin the industry. The Greyback and French's Cane Beetles, native insects that naturally ate grass roots, bored into the roots of sugar cane crops and were causing the plants to die and go brown. Control with poisons like arsenic trioxide, carbon disulfide and even 1,4 dichlorobenzene was failing badly, and the success of biological control against he prickly pear led influential politicians and the CSIR to believe the toad would eat the beetles.Unfortunately, toads cannot access adult beetles which fly away and the larvae live underground, so the experiment was a failure. European common toads (Bufo bufo) were tested for controlling grass grubs, but it was found they could not dig down to reach them - a basic quarantine process never done with cane toads.Since none of Australia's native animals have resistance to bufotenin (unlike other places where cane toads have been introduced), they have become more of a pest than the beetles ever were. Quolls, medium-sized carnivorous marsupials, have been very badly hit by poisoning from toads and now are largely confined to Tasmania where toads cannot reach (they sink in seawater). Many snakes have also declined badly where toads are present.Fertility control methods, though as yet unproven despite years of research, offer the only hope for control. However, I do not even know basic questions on this issue like how long poisonous toad eggs remain viable without sperm to fertilise them - I have assumed they would eventually die in the absence of sperm, but I have not found data.
What problem does the cane toad bring to the ecosystem?
Reason for introducing cane toad Cane toads, Bufo marinus were introduced into Australia to control the grey backed cane beetle and the frenchie beetle that were destroying sugarcane crops, they are still spreading across Australia. They failed to control the cane beetles, and became a major pest themselves. Cane toads can harm native wildlife by eating small animals and poisoning larger predators that try to eat them. Household pets are also at risk from poisoning. So far, there is no known way to control cane toads across large areas, but scientists are searching for a biological control agent that is specific to the toad. One hundred and one toads arrived at Edmonton in North Queensland in June 1935. Unseasonal breeding occurred almost immediately, and within 6 months over 60,000 young toads had been released.
What damage did the cane toad do to native species in Australia?
It causes problems for humans as the poisons from a cane toad can give us intense pain, temporary blindness and inflammation.And for pets it can affect them as well, signs are;-profuse salivation -twitching -vomiting -shallow breathing and collapse of the hind legs and the pet may fall into cardiac arrest within 15 minutes.Further information:Cane toads have become an ecological disaster in Australia, and other places to which they have been introduced.

What states in Australia have cane toads taken over?
Cane toads are widespread throughout the state of Queenslnd, and the northern part of the Northern Territory, particularly around Kakadu. They are now also encroaching further down the coast of New South Wales, having reached Yamba, and a colony has even been found as far south as Port Macquarie.
How do cane toads effect the a food web?
Cane toads affect the environment negatively by being an invasive species. This species invades other countries and takes away food sources from other native organisms. The cane toad is also toxic to predators, which would cause a pet to die if they were to eat a cane toad.They are an invasive species and they make other frogs compete for the food in the environment.
Why are cane toads bad?
Cane toads have become an ecological disaster in Australia. They eat the native wildlife, but have no natural predators. Cand toads eat native frog species, as well as other small burds and mammals, and they compete directly with native frogs and other species for food.

Where can cane toads be found in Australia?
It's not. This introduced pest has become an ecological disaster in Australia, spreading further and further south. Control has been impossible for several reasons. 1. The cane toad has no natural predators, although crows have learnt to flip the toads over and peck at the soft underbelly. 2. It breeds very quickly, and has invaded the native habitat of frogs, which simply cannot withstand its large, poisonous cousin. 3. Removal is the favoured method, but it does not work. The cane toad is its own worst enemy and major competitor, so when individuals are removed, it allows the remaining animals to thrive.
