What doe crutaceas eat?

Crustaceans are a diverse group of animals that have varied diets depending on their species. Many are omnivorous, feeding on algae, plankton, and detritus, while others may consume small fish, mollusks, or even other crustaceans. Some, like shrimp and crabs, are scavengers and will eat decomposing organic matter. Overall, their diet reflects their role in the aquatic ecosystem as both predators and prey.
