Question

How do hermit crabs choose and change their shells?

Answer 1

Hermit crabs choose and change their shells based on the size of the shell and how well it fits them. They have a soft abdomen that needs protection, so they search for shells that provide a secure fit and protection from predators. When a hermit crab outgrows its current shell, it will seek out a larger one to accommodate its growing body. Hermit crabs are known to be quite picky about their shells and will often try on several shells before finding the perfect fit.

Answer 2

Hermit crabs choose and change their shells based on the size, shape, and weight of the shell. They usually use their sense of smell and touch to assess if a shell is suitable for them. When they outgrow their current shell, they search for a new one to move into. This process is essential for their growth and protection.
