Crustacean ecology studies the relationships and interactions of crustaceans, a diverse group of aquatic animals that includes crabs, lobsters, and shrimp. These organisms play vital roles in their ecosystems, serving as both predators and prey. They contribute to nutrient cycling and help maintain the balance of aquatic environments. Crustaceans inhabit various habitats, from marine to freshwater ecosystems. Their adaptations, such as specialized appendages and exoskeletons, allow them to thrive in different conditions. Understanding crustacean ecology is essential for conservation efforts and managing fisheries, as these species are crucial for biodiversity and human economies.
