These species have similar traits which help to identify them, they have a : fast growth rate rapid reproduction high dispersal ability

One of these ecological effects is the canes toads devastating impact on the Argus monitor. The argus monitor has rapidly decreased 90% since the cane toad has been introduced. An economic effect has been the impact on the global economy. It is estimated that the global cost of invasive species management is equal to 5% of the global economy. Then there is the human harm that is caused by these species. In the cane toads case, people have been killed by eating and even have contacted with the toad in their mouths, due to their poison on its skin. Twitching, vomiting, shallow breathing, temporary blindness and intense pain are all the symptoms that can occur after eating the toad, however death can occur after 15
