Me i've looked it up and i can't find any answers.
1. dromedary camels in australia
2. comb jellyfish (ctenophores) in the black sea
3. piranhas in the united states
was the introduction intentional or accidental for the things above?
how did it happen?
why did the organism do well in the new environment?
what was the effect on the native environment?
what efforts have been made to eliminate or reduce the numbers of the organism?
what is the status right now of the organism in the new environment (has it been eliminated, or does it still flourish)?
