How does crabs get nutrients?

Crabs obtain nutrients primarily through their diet, which consists of a variety of organic matter, including algae, plankton, mollusks, and detritus. They use their pincers to grasp and break down food before ingesting it. Crabs also have specialized digestive systems that allow them to extract essential nutrients from their food efficiently. Additionally, some crabs filter feed by sifting through sediment to capture tiny particles.
