The cane toad is one of the largest toads. It measures about 9 inches (23 centimeters) long. The cane toad is native to tropical America. But it has become a serious pest in Australia. It is also called the marine toad or the giant toad.
The cane toad feeds mainly on insects. However, it will eat almost any kind of small animal. These include frogs, lizards, snakes, mice, and birds. The toad can lay up to 20,000 eggs at once. The toad has a pair of large glands on top of its head. These glands produce poisons. These poisons make the toad taste bad. The poisons can sicken or kill animals that feed on the toad.
The cane toad was brought to Australia in 1935. The toads were brought in to help control beetles. The beetles attack sugar cane. Since then, cane toads have spread across much of Australia. They have done great damage to native wildlife. Many animals have died after eating cane toads. Cane toads also compete with native animals for food.
