 Atlantic Rock Crab                Family Cancridae
                                   Cancer irroratus 

Rock crabs live in the benthic zone (bottom) of the ocean and bay. They are able to adapt to extreme variations in depth.

The depths that they exist at range from deep waters at 2,600ft. to very shallow waters and occasionally well inland from the low tide line

They live on a variety of substrate types including rocky and loose material.

Smaller crabs with the cephalorthorax width of about 50 mm tend to inhabit muddy or sandy bottoms, while other crabs seem to prefer the rocky bottoms

Economic Importance for Humans: Positive

The rock crab industry provides economic benefits. This fishery in the Atlantic Ocean is generally new. Lobsters have been the most popular fishery in this region over the years. The rock crab fishery first began in the 1970's but took several years to grow into an industry. As more markets developed for the seafood industry interest began to rise about the rock crab.
