Here are some more facts about hermit crabs, according to Google:

• Hermit crabs don’t grow their own shells. Instead, they inhabit empty shells of other mollusks for protection.
• As they grow, they must find larger shells, leading to a constant search and sometimes even fights over suitable homes.
• Despite their “hermit” name, they are often social creatures, living in groups.
• Hermit crabs undergo molting, shedding their exoskeleton to grow larger. This process leaves them vulnerable until their new exoskeleton hardens.
• There are over 800 species of hermit crabs, found in both aquatic and terrestrial environments.
• Both aquatic and terrestrial hermit crabs use gills to breathe. Terrestrial hermit crabs have adapted gills that allow them to extract oxygen from the air, but they still require moisture.
• They will often gather in groups, and line up according to size, and exchange shells. This is done to make sure everyone has a shell that fits.
• They can communicate by making chirping sounds.
