Yes, unfortunately there are loads. One of the biggest problems is animals being transported through ship ballast water. A famous example is that of the comb jelly
upsetting annihilating the food web in the Black Sea.
And perhaps the most recent and ongoing problem is the proliferation of Lionfish in the Meso-American Barrier Reef. My bestie Jen is in Belize and one of her projects is developing a supply chain to harvest these invasive lionfish to sell internationally - protecting the reefs and providing alternative incomes for local communities!
