Silver carp leaps from water when startled, but bighead carp do not. They are both filter feeders, but bighead feeders filter larger particles.

2. It's technically native to china and the earliest confirmation of it being in taiwan in around 1800 (although it could have been earlier) ([url]https://www.researchgate.net/publication/296813573_Overview_of_the_global_distribution_and_control_of_the_Formosan_subterranean_termite[/url])
3. It is in a small part of mexico, but some sources say it isn't established, so saying taiwan or japan might be a safer bet
