A great majority are marine (salt-water) species, ranging in habitat from tidal zones to depths exceeding 8,800 m (5.5 mi), though there are freshwater species. All adult sponges are sessile, meaning that they attach to an underwater surface and remain fixed in place (i.e., do not travel). While in their larval stage of life, they are motile.
Spongilla is a genus of freshwater sponges containing over 200 different species. Spongilla was first publicly recognized in 1696 by Leonard Plukenet and can be found in lakes, ponds and slow streams. [2] Spongilla have a leuconoid body form with a skeleton composed of siliceous spicules.
More than 8000 species of sea sponges live in oceanic and freshwater habitats. [1] Sponge fishing historically has been an important and lucrative industry, with yearly catches from years 1913 to 1938 regularly exceeding 181 tonnes and generating over 1 million U.S. dollars. However, this demand for sea sponges has seen catch rates peak and in ...

Freshwater molluscs are those members of the phylum Mollusca which live in freshwater habitats, both lotic (flowing water) such as rivers, streams, canals, springs, and cave streams (stygobite species) and lentic (still water) such as lakes, ponds (including temporary or vernal ponds), and ditches.

This zoochlorellae may augment or supplement their sponge host's nutrition. Also, because of being a susceptible and responsive freshwater animal, Anheteromeyenia species are potentially very valuable indicators of water quality.
