Carcini

Carcini, also known as Cancer, is a genus of crabs that includes several species found in various marine environments. The genus is characterized by its distinctive pincer-like claws, which are used for both defense and feeding. Carcini crabs are known for their ability to walk sideways, a unique adaptation that allows them to move efficiently along the ocean floor.

One of the most well-known species in the genus Carcini is the Cancer pagurus, commonly referred to as the European green crab. This species is native to the eastern Atlantic Ocean but has become invasive in many parts of the world, including Australia, New Zealand, and the United States. The invasive nature of the Cancer pagurus has had significant ecological impacts, as it competes with native species for resources and can outcompete them for food and habitat.

Another notable species is the Cancer borealis, also known as the snow crab. This species is found in the northern Atlantic Ocean and is an important commercial species, particularly in Canada. Snow crabs are known for their large size and are harvested for their meat, which is used in various culinary applications.

Carcini crabs play a crucial role in marine ecosystems, serving as both predators and prey. They contribute to the food web by feeding on a variety of marine organisms and, in turn, being preyed upon by larger predators. Their ecological importance highlights the need for conservation efforts to protect these species and their habitats.
