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.
Invertebrates cells fire in response to similar stimuli as mammals, such as tissue trauma, high temperature, or changes in pH. The first invertebrate in which a neuron cell was identified was the medicinal leech, Hirudo medicinalis. [14] [15] Learning and memory using nociceptors have been described in the sea hare, Aplysia.

Of all evaluated invertebrate species, 6.1% are listed as near threatened. The IUCN also lists 15 invertebrate subspecies as near threatened. No subpopulations of invertebrates have been evaluated by the IUCN. This is a complete list of near threatened invertebrate species and subspecies as evaluated by the IUCN.
Additionally 5278 invertebrate species (29% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
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. Others are kept to serve a functional role such as consuming algae in the aquarium.
