Bothriocephalus acheilognathi (Asian fish tapeworm) – in the past few decades this tapeworm has spread from its native East Asia to all continents except Antarctica, largely thanks to the aquaculture and pet trade. A parasite of over 200 fish species, infections of B. acheilognathi negatively impact the aquaculture industry and have been responsible for 90% mortality rate in grass carp in the past. Environmental impacts are still largely unknown, but the Asian fish tapeworm is thought to be adversely affecting some endangered species.

Deparia petersenii subsp. petersenii (Petersen’s lady fern) – an aggressive, fast-growing perennial fern that can form thick ground cover and outcompete native plants. Native to Asia, New Guinea and Polynesia, Petersen’s lady fern has been introduced as an ornamental and is now invasive in Madeira, the Azores, southeastern USA, southeastern Brazil and Hawaii.

Trioceros jacksonii (Jackson’s chameleon) – native to Kenya and Tanzania, this chameleon has been introduced via the pet trade to California and Hawaii. It may pose a threat to native Hawaiian insects and snails that it preys on.
