The genus *Pagurus* includes many species of hermit crabs, notable for their spiraled abdomens and reliance on shells 🐚 for protection. These crabs can be found worldwide in marine environments. Their soft, vulnerable abdomens make shell-dwelling crucial for survival. They are opportunistic scavengers, feeding on whatever they can find. Essentially, they're the resourceful survivalists of the sea, constantly adapting. Think of them as tiny, armored nomads always seeking shelter.
