seagulls, larger fish
Most crabs are omnivorous, meaning they eat whatever they can get. They feed mostly on algae but take other food including worms, molluscs and other crustaceans, bacteria, fungi and other organic waste depending on the species and their availability. Most crabs eat both plant and animal matter, but some are specialized to eat plankton or shellfish, and some actually catch fish.
