[24] Extinction rates of many species may increase severely into the next century because of invasive species, loss of keystone species, and species which are ...

They usually live between grains of sediment, swimming as plankton, or crawling on other organisms, such as algae and corals. [1] With the exception of two acoel freshwater species, all known acoelomorphs ...
