In the United States, there are typically two species sold in captivity for pet ownership. The two most popular crabs in the United States are:
Coenobita clypeatus
Native homeland – Caribbean, live inland
Common nicknames – Caribbean crab, land hermit crab, purple pincher (PP), tree crab, or soldier crab
Distinctive Characteristics – has a large purple pincher claw, tan-colored head with round eyes, speckles on claws and legs called setae (rigid, hair like bristles) covering its body, dark purple legs with red or orange, left walking leg maneuvers with large purple claw
Coenobita compressus
Native homeland – Ecuador, live at the seashore
Common nicknames - Ecuadorian crab, E-crab, E, or Eccie
Distinctive Characteristics – has same-colored claws and darker leg tips than the Ecuadorian crab, stripes on the sides of the head with elongated eyes, only has small amount of setae on both front claws, vary in color from orange to tan to gray, uses two left legs
Activity – generally more active than the Caribbean crab and make chirping noises
Special Needs – need salt water in their tanks to drink and bathe in
The Caribbean and Ecuadorian land hermit crab species will live together quite comfortably.
If these two descriptions do not fit your land hermit crab, then it is probably an exotic breed imported from the Pacific Rim to the United States.
