The 'monster' toad venom is enough to kill a 'reappearing' dog

Scientists worry that this is the "ideal breeding season" for the poisonous cane toad.

The cane toad species originating from South America, Central America and parts of southern Texas just appeared in South Florida at a time when Florida was experiencing the rainy season.

The toads are yellow brown, weigh up to 2.6kg and are about 38cm long. They have glands behind the eyes that contain milky white toxins that can kill a dog. This toxin can also burn or irritate the eyes.

In some cases, some people die from ingesting this toad's egg.

Recent heavy rains in South Florida are creating conditions for them to breed. "As soon as there's water to breed, the cane toad will thrive," said William Kern, associate professor at the University of Florida.

Due to the early rainy season, sugarcane toads are expected to thrive.

In addition to posing a threat to the health of humans and pets, these giant toads can also harm the environment. They eat almost all insects with their pet food, reducing the food of other species.

An omnivore, the cane toad is willing to make frogs, snakes, other mammals, even fellow humans.

Cane toad are classified as invasive in 20 countries. The Florida Conservancy of Fish and Wildlife recommends that people kill them if confronted.
