Definition of bryozoan in English:



  • A sedentary aquatic invertebrate of the phylum Bryozoa, which comprises the moss animals.

    • ‘Commonly, the host is a brachiopod, but it may be a coral, bryozoan colony, crinoid stem, or mollusk.’
    • ‘Interspersed among the archaeocidarids are three less common echinoid species as well as occasional crinoids, brachiopods, bryozoans, and rare edrioasteroids and asterozoans.’
    • ‘They include bivalves, brachiopods, bryozoans, crinoids, gastropods, a possible monoplacophoran, nautiloids and a possible serpulid or microconchid.’
    • ‘The greatest tentacle length in a bryozoan lophophore known to us is 1.2 mm, reported by Cook from a highly obliquely truncate lophophore in a colony of the ctenostome Flustrellida hispida.’
    • ‘There are more than 50 fish species whose lives are linked to Sargassum, and a myriad of invertebrates, including gastropods, polychaetes, bryozoans, anemones, and sea-spiders.’


  • Relating to or denoting bryozoans.

    • ‘Erect forms were much more common in the Paleozoic than they are now; the majority of today's bryozoan species are encrusting.’
    • ‘Many of the 5000 or so bryozoan species exhibit polymorphism.’
    • ‘Individuals within all bryozoan colonies are relatively small.’
    • ‘It is apparent that mining of bryozoan branches weakened them, thus making them subject more readily to breakage by wave action.’
    • ‘Bryozoan colonies are important food sources for some sea slugs and fish.’
