Hermit crabs are fond of their shells. As they grow, these soft - bellied creatures swap their borrowed homes for new ones, leaving the old shells for smaller crabs. This 'real - estate deal' happens in coastal waters globally. Crabs are ancient, pre - dating dinosaurs and surviving multiple mass extinctions. They belong to the crustacean group that dates back to the early Cambrian period. Their family tree includes lobsters, shrimp, and spiders. Scientifically named Pagurus berhardus, these cute hermit crabs, about an inch long (think of a large blueberry with legs), are perfect for ocean - themed parties, school units as giveaways, study tools, or prizes.

These hermit crab figures are great for adding a fun ocean touch. You can use them as party favors at ocean - themed parties, just place them on the tables. For school units, they can be used in science lessons to teach about marine life. When using them as prizes, simply hand them out to the winners. As for maintenance, they don't need much. Just keep them in a dry place to avoid any damage. Be careful not to drop them as they're small and could break easily. And that's all you need to know to enjoy these hermit crab figures!
