Aquatic invertebrates, including crustaceans and mollusks, are a diverse group of small aquatic animals that lack a backbone. They play crucial roles in aquatic ecosystems, serving as both predators and prey, contributing to nutrient cycling, and supporting food webs. Common examples include crabs, shrimp, clams, oysters, snails, and octopuses. These organisms are vital for ecological balance, economic activities like fisheries and aquaculture, and have cultural significance in various societies.
