Modern species inhabit freshwater, brackish, and marine environments.

A fossil’s paleoecology depends on many factors of their paleoenvironment. These include physical conditions, such as temperature, light, water depth, and energy (calm vs. turbulent), and chemical conditions, such as salinity, pH, oxygen, and toxic chemicals. Some animals will thrive if these variables change, and others will die off.Bryozoans, like brachiopods, contain a tentacle-bearing lophophore used in feeding and gas exchange.
