- Most frogs identify prey by movement, and vision appears to be the primary method by which the cane toad detects prey; however, the cane toad can also locate food using its sense of smell.
- The cane toad has a high tolerance to water loss; some can withstand a 52.6% loss of body water, allowing them to survive outside tropical environments.
Cane toads are the largest toad in the world and have dry, warty skin, and are native to the southern United States, Central America, and tropical South America. Their name originates from when they were used to eradicate pests from sugarcane. However it now has many other common names, including "giant toad" and "marine toad."
Their size can vary quite a lot as they can be anywhere between 5 and 23 centimeters in length and they can weigh over 2 Kilograms. Females are generally much larger and can live for 10 - 15 years in the wild and up to 20 years in captivity. The diet of a Cane toad includes insects, small snakes, frogs, lizards, and mice. They can also survive for long periods without water. Cane toads lay large quantities of eggs and they breed throughout the year after rain.
Cane toads are a massive threat to local species when they are introduced to a new environment. They can now be found in over 20 different countries and are thriving because of few natural predators, they breed easily, and they have abundant food. They are also very dangerous to other animals due to their milky toxin, known as bufotoxin, which is secreted when they are in danger. Bufotoxin is a complex cocktail of 14 chemicals that can kill an animal in 15 minutes if swallowed.
