The Atlantic rock crab, scientifically known as Cancer irroratus, is a species of crab native to the western Atlantic Ocean, particularly found along the coastlines of North America from Newfoundland to North Carolina. It is also commonly referred to as the peekytoe crab or the rock crab.
This species is characterized by its stout body, broad carapace, and strong pincers that are located on the ends of its front claws. The carapace of an adult Atlantic rock crab can range in color from dark brown to greenish-brown and is covered with small spines and tubercles, providing camouflage and protection from predators.
Atlantic rock crabs are typically found in intertidal zones and along rocky shores. They are opportunistic scavengers and predators, feeding on a variety of organisms such as mussels, clams, barnacles, small fish, and dead animals. Their powerful claws are used to crush and break open shells for accessing the soft tissues.
The Atlantic rock crab is an important species both ecologically and commercially. It provides a source of food for various predators, including fish and seabirds. In the commercial fishing industry, it is sought after for its meat, which is considered to be sweet and delicate. Its popularity has led to its cultivation and widespread availability in seafood markets.
Due to its abundance and relatively short lifespan, the Atlantic rock crab is considered a highly sustainable seafood choice. It is regulated by fishing quotas and management measures to ensure its long-term viability.
