Life-cycle - Cane Toad Population Successful

The water of any nature is essential for survival and reproduction. Cane toad can produce eggs ranges from 8,000 to 35,000 at a time. There are two conditions for healthy development which are described as follows:

• The slow flowing water must be avaible for the toad.
• 25-30 degree C temperature is needed for healthy development.

In this way, cane toads make population successful during the life cycle.

Cane Toads are very strong and adaptable, they are also poisonous throughout its life cycle, which is why they only have a few predators and have a life span of 10-15 years. Cane toads have poison glands, and the tadpoles are extremely toxic to most animals if consumed. They are productive breeders, they only need a small pool of water of almost any nature. The female cane toads can lay 8,000 to 35,000 eggs at a time and may produce two clutches in one year. The eggs will hatch within 24-72 hours and the tadpole stage may last from three to twenty weeks. Cane toads in the tropics grow really quick and may be sexually mature only within one year. Cane toads have been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control because of their ravenous appetite, however, they are now considered pests and are dangerous to humans and animals, both wild and domesticated especially to dogs.
