Hermit crabs live in shells. As they grow, they need to move into bigger and bigger shells. The process of upgrading shells is called “molting.” The molting process takes 4-8 weeks and hermit crabs will molt every 12-18 months. Since hermit crabs can live for more than 30 years, this means that they can potentially molt 30 times in their lifespan.
