Cane toads (Bufo marinus) in the wild can live up to ten years. In captivity they can live up to about eight years.

What adaptations help tadpoles live in water?
they have gills,and a long flat tail to help them swim before they become frogs or toads. they have gills so they can breath in the water....
How long to tadpoles turn to frogs?
It can be as short as a couple months (Cane Toad) or as long as 1 to 3 years (Bullfrogs.)
How long does it take for tadpoles to become adults?
It takes about 100 years.
Why did the cane toad experiment fail?
In 1935, cane beetles were devastating the sugar industry in Australia. The grubs would burrow into the ground and destroy the roots of the sugar cane, causing it to die before it could be harvested. Farmers and scientists were desperate for anything that might work. They imported approximately 100 cane toads into Australia. They had discovered that the cane toads ate cane beetles - but only when they were in a laboratory, hungry, and offered no other food. Once arrived in Australia, the toads found other food sources (like smaller beetles and moths) much more to their liking. They reproduced prolifically. In the simplest sense, the experiment failed because the cane toads did not work as a biological control method. They did not eat the cane beetles when there was another food source available, and there was always something more palatable for them to eat. In the broader sense, it was a failure because it has been an environmental disaster for Australia. Cane toads eat anything, and outcompete native species for food. They are poisonous, so species that prey on non toxic native frogs (such as snakes and carnivorous birds, lizards and mammals) eat the toads and die because very few have learned to recognise them as harmful. Cane toads produce far more eggs in proportion to body size than most native frogs, and will breed in stagnant or brackish water that most frogs will reject. Toad tadpoles are extremely aggressive, and cause damage to local waterways. They eat the spawn and tadpoles of most native frog species and strip away all the food, starving any that are left. They develop rapidly and overrun the land. Cane toads are extremely adaptible. They can live in virtually any habitat as long as they can find breeding sites (any still water) and food (almost any insect). They have spread over vast swathes of the Australian north. They are ugly, they kill pets, and they have caused immeasurable damage to the environment. The cane toad infestation in Australia was the result of a poorly designed experiment which was implemented far too soon.
What is so unique about the cane toad?
Well the cane toads were actually introduced by the Austrailian government to get rid of the cane magets that were hurting the cane farmers crops. However, the never actually did this and spread rapidly through out the country. They found the solution to the magets years later and got rid of them with pesticide. Also, this doesn't relate to the question, but all the cane toads in Australia originate from the 12 originals that were brought to the country.
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.
What kind of frogs eat worms?
They will eat anything that fits in their mouth as long as it is not poisonous or harmful.
Are toads poison?
When cane toads are threatened, their glands secrete a milky-white fluid known as bufotoxin. Components of bufotoxin are toxic to many animals. There have even been human deaths due to the consumption of cane toads. Yes. Toads naturally secrete a poison from their skin. If they think they are going to be eaten, they will also create a sticky, white, glue-like poison from glands behind their eyes. Toad poison is not fatal to humans, but can give you a bad stomachache. However, it IS fatal to dogs, cats and various other animals. As another defense, most toads will pee on you when picked up. Toad pee has the same effects as toad poison, but can give you a worse stomachache. And, contrary to popular belief, toads DO NOT give people warts. Toads ARE safe to handle as long as you thoroughly wash you hands afterwards. (Sorry for the long answer.)
We found a cane rat in our garden will it become tame with handling?
Cane rats do in fact become tame with handling, and they live a very long time. If you train them long enough they will even understand simple commands such as "stay" and "stop"
How long ago did sugar cane become extinct?
Sugar cane is not extinct. It remains, along with sugar beets, the principal source of sugar in the world.
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.
How do get poison out of cane toad meat?
From what I understand, and amphibian's poison is in it's skin, and not in it's meat. I have skinned and eaten a cane toad, and I didn't get sick or anything. I did this because I am interested in wilderness survival, and I wanted to know if cane toads were edible. Having eaten one with no ill effect, I assume that they are in fact edible, as long as you skin them. I also harvested a lot of cane toad venom by squeezing the main poison glands of many toads, and I smoked quite a lot of it. It did not have any mind-altering affect on me whatsoever, however, I have since had unexplained health problems.
