Encrusting bryozoans form flat sheets that spread out over rocks, shells, and other substrates. Forms that grow upwards into the water column may be massive (solid), foliaceous (sheetlike, with zooids on both sides), dendroid (branchlike or treelike), or fenestrate (many branches joining and rejoining to form a netlike or "windowed" shape).Bryozoans are capable of both sexual and asexual reproduction.
