Asian carp
It is native to eastern Russia and China, and the main affected countries are North America and Europe. Asian carp refers to several carps native to Asia, including carp, grass carp, silver carp, bighead carp, etc., which were introduced as edible, ornamental and weeping fish in the early days due to their large size and appetite, and their rapid reproduction rate, posing a serious threat to local fish.
Zebra mussels
Native to the Black Sea, caspian sea and Aral Sea, the main victim countries are Russia, Europe and North America. Zebra mussels invade mainly by means of ballast water and hull attachment on cargo ships.
Zebra mussels feed on plankton and reproduce at an alarming rate, squeezing the living space of local fish, and zebra mussels can attach to any hard surface through filaments, blocking pipes and facilities and contaminating water sources.
Sugarcane toad (American giant toad)
It is native to northern South America and Central America, and the main victim countries are warm climate areas represented by Australia. Sugarcane toads were introduced early as a means of controlling pests of local crops. This fertile and venomous species is rarely touched by animals, and can lay more than 30,000 eggs at a time, preying on almost everything that can be swallowed.
Wild Kudzu
Originating in East Asia, the main victims are North America and Europe. Kudzu was introduced as an ornamental and edible plant (kudzu).
Wild kudzu is tenacious, and can grow nearly 30 centimeters a day under suitable conditions, causing a wide range of rapid spread, so that other plants can not obtain the sunshine and nutrients to survive and die in a large area.
Water hyacinth (hyacinth orchid)
Native to the amazon rainforest waters of western Brazil, the main victims include Africa, Asia, North America and Australia. Water hyacinth was introduced early as ornamental plants, animal feed, etc.
Without natural enemies to balance, the water hyacinth can double in size within a few days under the right conditions, blocking the river channel, consuming oxygen, blocking sunlight, and leading to a sharp deterioration of the local ecosystem.
European starling (purple-winged starling)
It is native to Europe, Asia and North Africa, and the main victim countries are North America, Australia and South Africa. It was also introduced as a means of controlling pests. European starlings are known for their movements and aggressiveness, wreaking havoc on crops and other bird habitats.
Asian Star-spotted Celestial Bull
It originates in China, Japan, and South Korea (I used to catch and play with them as a child), and the main victim countries are North America and Europe. Mainly through wooden packaging materials and wood imports.
The star-spotted celestial bull has no natural enemies in the new environment, multiplies in large numbers and is not picky eaters, the larvae moth in the trunk, and the adults eat the trunk and branches.
Indian kitten ferret
Originating in Southeast Asia, the main victims are other parts of Asia, Central and South America. Introduced early as a control of rat and snake infestations. There are no natural predators, and they prey on birds, reptiles and other small mammals in large numbers, and are also hosts of zoonotic pathogens such as rabies viruses
European rabbit
Native to Southern Europe and North Africa, the main affected countries include continents other than Asia and Antarctica. European rabbits were brought everywhere by colonists as a source of food and hunting objects.
Their exuberant fertility and food intake have a huge impact on vegetation, soil, local animal food sources and habitats.
North Pacific starfish
It originates in the waters surrounding East Asia and is mainly affected by Australia. Intrusion through the ship's ballast tank water and seafood transport methods.
North Pacific starfish are voracious predators, preying on crustaceans such as polyps, shellfish, crabs, worms, sea squirts, sea urns, and any other starfish they can find
