Bryozoan colonies of the species Pectinatella magnifica can form gelatinous masses as large as basketballs, although they are typically smaller. Bryozoans are colonial invertebrate animals that live in the water and build exoskeletons similar to those of corals.

Are bryozoans extinct?

With the exception of one order of stenolaemates, the Tubuliporata or Cyclostomata, all of these Paleozoic bryozoan lineages were severely impacted in the Permian extinction: cryptostomates disappeared at the end of the Permian (245 million years ago), while a few other lineages lingered until the end of the Triassic,

Are bryozoans living?

Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies.

Are bryozoans free living?

Abstract. Free-living bryozoans, unlike most cheilostomes, live unattached from the substratum on or within soft sedimentary bottoms. Bryozoans of the family Cupuladriidae Lagaaij, 1952 are probably the best-studied free-living representatives.

How long ago did bryozoans live?

Molecular evidence has long indicated that aquatic animals called bryozoans should be found among the fossils of the Cambrian period, around 541 million years ago.

Do fish eat bryozoans?
