The difference between corals and bryozoans is that "corals" is a hard substance made of the limestone skeletons of marine polyps and "bryozoans" is a member of the phylum Bryozoa of aquatic, usually colonial invertebrates. [from 19th c.]. Tags: bryozoans, coralsBryozoans They are aquatic invertebrates that live in sedentary colonies. Bryozoans live in tropical waters, polar waters and oceanic trenches. They have a crown of tentacles called lophophores that are used as feeding structures. They are classified into - Stenolaemata - Marine bryozoans Phylactolaemata - Freshwater bryozoansMar 9, 2023 · Marine bryozoan colonies tend to grow on or attach to solid substrates such as shells, rocks, large brown algae, mangrove roots, ship bottoms, and the undersides of icebergs. They live at all water depths and all latitudes. Growth forms of bryozoans are sometimes encrusted and coral-like and create miniature “reefs” in shallow water habitats.
