Crab Physical Appearance

Jonah Crab physical characteristics

The Jonah Crab, also known as Cancer borealis, is a species of crab that can be found along the eastern coast of North America. It has a robust body with a width that can reach up to 10 inches. The carapace, or upper shell, of the Jonah Crab is typically reddish-brown or dark green in color, and it is covered in small bumps and ridges. The claws of the Jonah Crab are large and powerful, with jagged edges that help them to crush their prey. The legs of this crab are long and slender, aiding in its mobility and agility.

Stone Crab physical characteristics

The Stone Crab, scientifically known as Menippe mercenaria, is another fascinating crab species found in the western Atlantic Ocean and the Gulf of Mexico. Its body is generally smaller compared to the Jonah Crab, with a carapace width ranging from 3 to 5 inches. The color of the Stone Crab’s carapace can vary, but it is predominantly brownish-red or gray. One notable feature of this crab is its large claws, which are asymmetrical in size. The larger claw is used for crushing shells and the smaller one for manipulating food. The Stone Crab’s legs are sturdy, enabling it to scuttle along the ocean floor.


Jonah Crab habitat

Jonah Crabs are predominantly found in the northeastern part of the United States, ranging from Cape Cod to northern Florida. They inhabit a variety of environments, including rocky intertidal zones, shallow coastal waters, and even sandy areas. These crabs prefer areas with ample hiding spots, such as crevices in rocks or submerged vegetation, which provide them protection from predators and shelter during molting.

Stone Crab habitat

Stone Crabs thrive in the warm waters of the western Atlantic Ocean and the Gulf of Mexico. They are commonly found along the coasts of Florida, as well as the Caribbean islands. These crabs have a preference for seagrass beds, oyster reefs, and coral reefs. Stone Crabs seek refuge in crevices or burrows, often excavated by other animal species, to protect themselves from predators and extreme weather conditions.


Jonah Crab distribution

Jonah Crabs have a relatively broad distribution along the eastern coast of North America. While they primarily inhabit the waters from Cape Cod to northern Florida, they can occasionally be found as far south as Georgia. They are particularly abundant in the Gulf of Maine and the Chesapeake Bay area due to the availability of suitable habitats and food sources.

Stone Crab distribution

Stone Crabs have a more limited distribution compared to Jonah Crabs. They are primarily found in the southeastern and Gulf coastal regions of the United States. Florida is particularly known for its abundant Stone Crab population, with the Florida Keys being a significant habitat for these Florida stone crabs. They can also be found throughout the Caribbean Sea, including the Bahamas and Cuba.

Jonah Crab shell

The shell, or carapace, of a Jonah Crab is thick and durable, offering excellent protection for the crab’s internal organs. It has a rough texture due to the presence of small bumps and ridges. The carapace color varies from reddish-brown to dark green, allowing the crab to blend in with its surroundings. One interesting aspect of the Jonah Crab’s shell is its ability to change color slightly when the crab molts and grows a new shell.

Similar to the Jonah Crab, the shell of a Stone Crab is also strong and sturdy. The carapace has a smoother texture compared to the Jonah Crab, but it still provides effective protection. The color of the Stone Crab’s shell varies from brownish-red to gray, offering camouflage in rocky or sandy habitats. During molting, the old shell is shed, and a softer one forms to accommodate the growing crab.

Color of Crabs

The coloration of Jonah Crabs can vary depending on their habitat and age. The carapace is typically reddish-brown or dark green, with some individuals showing hints of purple or gray. The undersides of their bodies are generally lighter in color, often ranging from white to yellowish. These color variations help Jonah Crabs blend in among rocky or sandy substrates, providing them with effective camouflage and protection.
