Soft shell crabs are soft and are eaten with the entire crab. Soft shell crabs are actually hard shell crabs that have shed their shells to allow for growth. Shells do not grow with the crab. Crabs retain a soft shell when they shed their hard shells; then that soft shells begins to harden-up as the crab grows.
Soft shell crabs are in season May through July.

Hermit Crabs are crustaceans like crabs and lobsters, however they have a soft very vulnerable body that is somewhat coiled upo itself. To protect this soft body from predators or any other threat, they use a hard shell. They can also retreat completely into this shell, which also helps predators from being able to pry them out.
