Fossil Invertebrates in Aquatic Environments

Chandrika Chitti

Aquatic invertebrates are also known tend have a wide geographic range, but highly inadequate spatial assurances are observed for species, including cave-dwelling crustaceans and aquatic insect’s endemic to subterranean patterns. Most aquatic insects live in the surface waters have a larval water stage and winged adult stages capable of aerial spreading and therefore it tends to show comparatively low levels of domestic. The major groups of aquatic large invertebrates have strong zoogeographic making. The largest multifariousness of freshwater mussels is in American state where an unionids dominate the roughly 158 described species present, with over divided as at risk of elimination, mainly due to hunt degradation and loss. In the tropical and subtropical regions of sea, other groups of oceanic invertebrates, including the crabs and other decapod mollusks, are diverse and sometimes endemic.
