The European green crab is considered invasive because it was introduced to North America and other regions, where it lacks natural predators. Its rapid reproduction and adaptability allow it to outcompete native species for food and habitat, leading to significant ecological disruption. Additionally, it preys on commercially important shellfish, such as clams and oysters, impacting local fisheries and economies. As a result, the green crab poses a threat to biodiversity and marine ecosystems in invaded areas.

What are American biologist worried about the European green crab?
American biologists are concerned about the European green crab (Carcinus maenas) due to its invasive nature and negative impact on local ecosystems. This species competes with native marine life for resources, preys on economically important shellfish, and disrupts habitats, particularly in coastal areas. The green crab's rapid reproduction and adaptability further exacerbate its spread, posing significant challenges for fisheries and biodiversity. As a result, researchers are actively monitoring its populations and exploring management strategies to mitigate its effects.
