Bryozoa, also known as Ectoprocta, is a major invertebrate phylum, whose members, the bryozoans, are tiny, aquatic, and mostly sessile and colonial animals. Reefal bryozoans however, do not show such depth-related species assemblages; instead, the various species’ depth ranges overlap progressively and gradually, going down the reef front (Forereef/Reef Front), as documented on Bonaire’s reef-slope (Kobluk et al. Live colonies have been found under ice at water temperatures less than 2°C, although most bryozoans prefer much warmer water (>15°C; Wood, 2015). g. 008 to 10. 2009) but there are only four identification guides available A new species of Mucophyllum rugose coral encrusted by bryozoans, tentaculoid tubeworms, and tabulates from the upper Silurian of Saaremaa, Estonia. emarginata has to be reconsidered.
