Blue Crabs are the most common crabs on the East Coast. They have a very different look than the mitten crabs; they have a pointed carapace and lobed back feet used for swimming.
European Green Crab – These are common on the East Coast, they look similar but their carapace is more like a triangle rather than round like the mitten crabs. Also Green crabs have no central notch and no fur on their claws.
Shore Crabs – There are a few species of shore crabs on the East Coast. These crabs are small even as adults and have a square carapace and no fur on the claws. These crabs live under rocks along the shore.
