8 species of invertebrates in the most dangerous invasive water in the world

1. South Pacific Sea Star - Asterias amurensis

A. amurensis is a marine invertebrate native to China, Korea, Russia and Japan. This starfish species has been spreading to North America and Australia, causing serious impacts on populations of native mollusc species. In places where the density of these starfish is high, most bivalves and fixed or fixed invertebrate species are excluded.

2. Green crab Carcinus maenas

Blue crabs are native to Europe and North Africa. Green crab has been introduced into the US, Australia and South Africa. Green crab is a voracious carnivorous species with food ingredients including bivalve molluscs, especially mussels. In the imported areas of green, the decline in the number of other crabs and bivalve mollusks.

3. Cercopagis pengoi crustacean

Cercopagis pengoi is a small crustacean native to the Caspian, Azov and Arabian waters. This crustacean has invaded the Baltic Sea, Gulf of Riga, Finland and the Great Lakes. Here they proliferate and compete for food with fish, as it is a crustacean that eats many aquatic animals, increasing its fertility.

4. Zebra mussel - Dreissena polymorpha

Zebra mussels originate from the Caspy Sea and Black Sea. They have now invaded and adapted development in the UK, Western Europe, Canada and the United States. Mussels compete with floating animals for food and thus affect the natural food web. They also affect the ecological functions of native mollusks and cause huge economic losses.

5. Migrant slot crab - Eriocheir sinensis

Migratory slime crabs originating in Asia have contributed to extinction of native invertebrates in many places, which alter the habitat by burrowing operations and costing $ 100,000 each year for a number of industries (fisheries and ornamental fish).

6. Leidyi Combined Jellyfish - Mnemiopsis leidyi

Jellyfish Leidyi comb is native to western Atlantic, but the explosion of their populations in the Black Sea region has led to a huge change in the ecosystem structure here because they feed on juvenile meat. . In addition, they also eat live molluscs and crustacean larvae.

7. Mediterranean Boy - Mytilus galloprovincialis

Mediterranean mussels invade South Africa and are competing to replace native black and brown clams. Sometimes Mediterranean Mediterranean boys are also called green boys and are easily confused with Mytillus edilus. This is a species introduced into Hawaii and other parts of the United States.

8. Chinese mussels - Potamocorbula amurensis

Chinese mussels originated in Japan, China and Korea, were introduced into the United States and caused serious damage to the aquatic environment here because they were able to compete for the position of benthic communities. indigenous as well as destroy floating flora communities.
