How much does a hermit crab weigh and how big do they generally get?

The weight of a hermit crab can vary depending on the species, but they typically range from a few ounces to around one pound. In terms of size, hermit crabs can grow anywhere from half an inch to several inches in length, with the largest species reaching up to 12 inches across. It's important to note that hermit crabs can molt their exoskeletons as they grow, so their size and weight can fluctuate throughout their lifespan.
