Bryozoa

Membranipora membranacea, colonia bryozoi thallo algae adhaerens.

Bryozoa sunt animalia aquatica, fere semper composita,[1] colonias[2] scilicet coniunctorum membrorum efformantes. Quae membra zooides dicuntur, utpote animalibus similia, sed quae animalia strictissimo sensu dici nequeunt.[3] Corpus uniuscuiusque zooidis e polypide[4] organa fere omnia, inter quae lophophorum, continente et cystide, quasi sacco (nonnumquam cum exosceleto) polypidem circumcingente, constat; zooides autem funiculo connectuntur.[5] In taxinomia zoologica, Bryozoa tamquam phylum habentur.[6]

Numerus specierum Bryozoorum hodiernorum est 5869,[7] fossilium autem circiter 15 000.[8]
