How do hermit crabs in nature eat and what do they eat?

In nature, hermit crabs are opportunistic scavengers, primarily feeding on detritus, decaying organic matter, algae, and small invertebrates. They use their pincers to forage for food on the ocean floor and can also consume plant material, such as leaves and fruits. Additionally, they play a role in the ecosystem by helping to recycle nutrients. Their diet can vary depending on their habitat and the availability of food sources.
