No hermit crabs do not grow back skin
Crabs grow out of their shells and they also shed their skin to do that. Meaning they molt their skin.
When crabs need to grow, they must molt, which involves shedding their exoskeleton. This process allows them to expand and develop a new, larger exoskeleton underneath. After molting, crabs take in water to help expand their new shell and then harden it over time. This cyclical process is essential for their growth and development.
Sea cucumber
Absolutely. Everything that breathes air has lungs.
Crabs do not have testicles inside their shell; instead, they have external reproductive organs. Male crabs possess a pair of gonads, which produce sperm, located in their body but not enclosed within the shell. The shell serves primarily as a protective exoskeleton and does not contain reproductive organs.
Crabs are generally sea-dwelling, while shrubs grow on land. Not much chance for crabs to eat shrubs.
Hermit Crabs live on the bottom of the ocean and eat the grasses that grow on the bottom.
