Something curious happened along the way. In the early stages of the invasion, toads spread at a rate of about 10 km per year. A few decades later - already 20 km per year. By the time they reached Middle Point, they had "accelerated" to 30 miles a year. When the researchers measured the toads, they realized what was going on. These northern toads had significantly longer legs than those of Queensland. And this trait was inherited. The Northern Territory News ran the story on the front page under the headline "Supertoad.
The article featured an image of Superman with the head of a toad. “Nightmare toads are already on our moible number data territory, and now they are evolving,” the newspaper wrote in a panic. Contrary to all Darwin's assumptions, it seemed that we were seeing evolution in real time. ; from a human point of view, they are also ugly: they have bony heads and an evil grin on their muzzle. But what makes these amphibians truly "nightmarish" is that they are poisonous.

If an adult aga toad is bitten or startled, it releases a milky-white mucus containing substances that stop the heart. Dogs often suffer from this poison, with symptoms ranging from frothing from the mouth to complete cardiac Previously, there were no poisonous toads in Australia; in fact, there were no toads at all. So the story of the aga toad is the story of the Asian carp in reverse. If carp are a problem in the United States because no one eats them, Therefore, the local fauna in the process of evolution has not learned to fear them.
