What is a Hermit Crab?
Hermit crabs belong to the superfamily Paguroidea and are characterized by their soft abdomens, which they protect by inhabiting empty shells. Unlike true crabs, which have a hard exoskeleton, hermit crabs must find and switch shells as they grow, making them unique among crustaceans.

There are several species of hermit crabs, but some of the most common include:
1. Caribbean Hermit Crab (Coenobita clypeatus) - Known for their vibrant colors, they are often found in pet stores.
2. Ecuadorian Hermit Crab (Coenobita compressus) - These crabs are smaller in size and have a distinct shell shape.
3. Purple Pincher Hermit Crab (Coenobita variabilis) - Recognized by their purple pincers, they are hardy and easy to care for.
4. Strawberry Hermit Crab (Coenobita perlatus) - These are popular due to their attractive appearance and sociable nature.
