Aquatic macroinvertebrates are insects in their nymph and larval stages, snails, worms, crayfish, and clams that spend at least part of their lives in water. These insects play a large role in freshwater ecosystems by recycling nutrients as well as providing food to higher trophic levels.
Macroinvertebrates within the same system may be residents from several months to multiple years, depending on the lifespan of each organism. Consequently, macroinvertebrate communities inhabit aquatic ecosystems long enough to reflect the chronic effects of pollutants and yet short enough to respond to relatively acute changes in water quality.
Aquatic macro invertebrates have some general characteristics that make them very useful to assess stream health: They are abundant and found in water bodies throughout the world; They are not extremely mobile; They carry out part or all of their life cycle within the stream or river.
All sponges are sessile aquatic animals. Although there are freshwater species, the great majority are marine (salt water) species, ranging from tidal zones to depths exceeding 8,800 m (5.5 mi).

The Aquatic Macroinvertebrate Collection is a Queensland Government scientific collection based in Queensland, Australia. The collection consists of aquatic macroinvertebrate (large invertebrates) specimens from rivers, streams, springs, wetlands, and other freshwater sources in Queensland. [1]
This is a list of invertebrates, animals without a backbone, that are commonly kept in freshwater aquaria by hobby aquarists.Numerous shrimp species of various kinds, crayfish, a number of freshwater snail species, and at least one freshwater clam species are found in freshwater aquaria or '0' salinity water body.
This is a list of various species of marine invertebrates, animals without a backbone, that are commonly found in aquariums kept by hobby aquarists.Some species are intentionally collected for their desirable aesthetic characteristics.
Aquatic-terrestrial contaminant subsidies originating in the aquatic environment can be transported across ecosystem boundaries, primarily mediated by organisms. [35] The transmission of contaminants can have negative ecological consequences that amplify up the food chain , including reduced nesting success of birds , [ 36 ] disruptions to ...
