Can hermit crabs keep growing if they get bigger shells?

    In the wild some hermit crabs can grow up to the size of a cantaloupes.  Depending on the species they do have growth limitations.  They do not grow to an infinite size.

    Hermit crabs grow naturally at steady rates, and they swap to newer, bigger shells out of necessity as a result of their growth. Depending on type (species) of hermit crab, some can be very picky about the shells they occupy. Some shells may be too big, which can inhibit a crab’s movement from place to place, and others may be too small, which prevent them from retreating. Essentially, a shell is a crab’s live-in RV. But it is also it’s only defense mechanism. Thus, hermit crabs will change shells many times throughout their lifetimes to best suit their needs during each interval.
