Hermit crabs lay their eggs in the ocean. They live among plankton as hatchling zoea. When they become a megalops they begin the long journey back to land to find a shell. Hermit crabs can spend a long time away from the ocean, even carrying water in their shell and only returning to flick their eggs into intertidal pools. While it's claimed that they can be bred in captivity, it's a difficult process and not fiscally reliable, so all commercially sold crabs are caught wild.
