Toad mating with an "alien" frog

This is a rather interesting behaviour. A native male Asiatic Toad was trying to mate with an introduced American Bull Frog. also another male. Perhaps the toad was simply fascinated by the size of this unusual expatriate without knowing the risk involved in this sexual indulgence - American Bull Frog is known to gorge anything that fits into its huge mouth, including its own kind. Well, here is one example of how an introduced species can affect our ecosystem.
