List of brackish aquarium invertebrate species explained

This is a list of various species of invertebrates, animals without a backbone, that are commonly found in brackish aquariums kept by hobby aquarists. Some species are intentionally collected for their desirable aesthetic characteristics. Others are kept to serve a functional role such as consuming algae in the aquarium. Some species are present only incidentally or are pest species.
