An invasive species is an organism that is not native to an ecosystem, and thus has no natural predators in that environment.
This lack of predators often causes some wicked problems in the place it colonizes. With no predators, these invaders can out-compete local fauna and flora, and then disrupt the balance of the ecosystem.
You might be wondering, how do these species get to their new location? Well, some are introduced purposely by humans, such as the European hare which was brought to Australia in the s, and some are introduced by accident, like the emerald ash borer, which has wiped out native ash trees in the Midwest and the Eastern United States.
Explore the new worlds of these alien species with this collection of resources. It is also very important to make sure that you have properly identified the animal as a cane toad and not a native southern toad, which is a beneficial part of the Florida ecosystem. Cane toads are not protected in Florida except by anti-cruelty law and can be removed and humanely killed on private property year-round with landowner permission.
Adult cane toads range in size from inches long, while southern toads only grow to inches long. Southern toads will have well defined cranial crests which look like ridges or horns above their eyes and a small, oval shaped gland visible behind their eyes.
Cane toads do not have crests above their eyes and possess a larger, triangular shaped gland behind their eye. This video from the University of Florida Institute of Food and Agricultural Sciences goes over some methods to humanely capture and kill cane toads.
If your pet bites or swallows a cane toad, they can become sick and die in as little as 15 minutes without proper treatment.
Symptoms may include frantic or disoriented behavior, brick red gums, seizures, and foaming at the mouth. If you see these symptoms, follow these steps:. This instructional video from the University of Florida's Institute of Food and Agricultural Sciences outlines these steps.
Thoroughly wash your hands after coming into contact with a cane toad, as you would after touching any wild animal. Escaped or released pets remain a primary source of introduced species in Florida, and it is illegal to introduce nonnative species into the state. This program helps reduce the number of nonnative species being released into the wild and fosters responsible pet ownership by giving pet owners a responsible and ecologically sound alternative to releasing an exotic animal.
Note: The FWC does not rehome wild-caught nonnative wildlife. Cane toads in Australia now number into the millions , and their still-expanding range covers thousands of square miles in northeastern Australia. The poisonous toads kill both pets and native species when animals bite, lick, or eat them, and they outcompete native species for resources like food and breeding habitat. Cane toads secrete a milky poison from the parotoid glands behind the shoulders. The poison, called bufotoxin , contains several different chemicals, such as bufagin, which affects the heart, and bufotenine, a hallucinogen.
They breed almost any time of year and lay eggs—between 8, and 30, at a time—in long strings in fresh water. Both eggs and tadpoles are also poisonous. They're highly adaptable and can be found in urban and agricultural areas, as well as dunes, coastal grasslands, and the edges of rainforests and mangrove swamps.

Once fertilised, female cane toads lay anywhere between 8, to 30, eggs - twice a year! These eggs hatch within days and tiny tadpoles emerge. These tadpoles are less than 3. Adult cane toads can live between years in the wild. Cane toads eat almost anything Cane toads will eat anything they swallow - both dead and living.
This includes pet food, carrion and household scraps, but mostly they exist on a diet of living insects. Will you help native Australian species survive the devastating cane toad invasion?
