Coenobita clypeatus, or the Caribbean Hermit Crab, is a fascinating crustacean species found in tropical and subtropical regions worldwide. These hermit crabs are renowned for their unique habit of utilizing discarded gastropod shells as protective shelters for their soft abdomens. As they grow, they periodically abandon their old shells in search of larger ones, engaging in a process known as "shell switching." Interestingly, competition for suitable shells can be intense among hermit crabs, with individuals sometimes engaging in shell fights or even forming "conga lines" to investigate new shells collectively.

One intriguing aspect of Coenobita clypeatus is their complex social behaviors. While they are primarily solitary creatures, they often congregate in groups, called "hermit crab congregations," particularly around sources of food or water. These gatherings provide opportunities for social interactions, mating, and sharing information about potential resources. Additionally, Coenobita clypeatus is a highly adaptable species, capable of thriving in various coastal habitats, including sandy beaches, mangrove forests, and even human-modified environments such as coastal cities. Their ability to utilize a wide range of habitats and their fascinating behaviors make them a subject of interest for researchers and beachgoers alike.
