As they did so, corals that had settled on the surface of the bryozoan became ever more deeply embedded, while maintaining an opening on the surface by growing at the same rate as the host bryozoan.What Bryozoa are not: Bryozoa are not corals. While colony shapes sometimes resemble the branching forms that we are familiar with for modern corals, there are some easily observable differences.
