Abstract The article is devoted to individual behaviour of autozooids (mainly connected with feeding and cleaning) in 40 species and subspecies of marine bryozoans from the White Sea and the Barents Sea. We present comparative descriptions of the observations and for the first time describe some of autozooidal activities (e.g. cleaning of the colony surface by a reversal of tentacular ciliature beating, variants of testing-position, and particle capture and rejection). Non-contradictory aspects… 
Comparative morphology of the nervous system in three phylactolaemate bryozoans
TLDR
The structure of the nervous system in Fredericella sultana suggests that it underwent a secondary simplification following the reduction of the lophophore arms, and the revealed distribution of various neuromediators in the nervousSystem allowed us to suggest functional affinities of some major nerves.
Group autozooidal behaviour and chimneys in marine bryozoans
TLDR
Group autozooidal reactions and different types of colonial behaviour were observed and recorded for 17 bryozoan species and subspecies from the White and Barents Seas, and three local collective reactions are described for the first time.
O anus, where art thou? An investigation of ctenostome bryozoans
TLDR
The purpose of this study is to assess the distribution of anus position among ctenostomes, analyse whether zooidal or colonial morphology affects anus position, and draw first conclusions on its functional effects.
In search of predictive models for stenolaemate morphometry across the skeletal–polypide divide
TLDR
A detailed analysis of morphometry within and across species is conducted and robust predictive models are attempted that can be used to infer the soft-body morphology from skeletal data, which will help with extracting data on ecology of Paleozoic communities of suspension feeders from the extensive bryozoan fossil record.
Some peculiarities in the behavioral reactions of the lophophore and the trophic structuring of the colonies of the post-Paleozoic Stenolaemata (bryozoa)
TLDR
Some peculiarities in the behavioral reactions of the lophophore, a feeding apparatus of the living marine bryozoans, are discussed and the types of trophic structuring of colonies can be used when characterizing taxa of different levels.
Trophic partitioning and feeding capacity in Permian bryozoan faunas of Gondwana
Bryozoans are epibenthic suspension‐feeders and use their ciliated tentacles to generate feeding currents. Modern bryozoan mouth size limits the size of the particles that can be ingested, and
Polypide anatomy of hornerid bryozoans (Stenolaemata: Cyclostomatida)
TLDR
The first detailed ultrastructural examination of the hornerid polypide, including tentacles, mouth region, digestive system and the funiculus, is provided, able to trace continuity and transitions of cell and ECM layers throughout the wholepolypide.

First evidence of virus-like particles in the bacterial symbionts of Bryozoa
TLDR
The ultrastructural research revealed replication of the viruses and/or activation of virus related elements in the bacterial symbionts inhabiting tissues of the marine colonial invertebrates (phylum Bryozoa) and indicates that Bryozoan may be new suitable model to study the role of bacteriophages and phage-related structures in the complex symbiotic systems hosted by marine invertebrate animals.
Key novelties in the evolution of the aquatic colonial phylum Bryozoa: evidence from soft body morphology
TLDR
Overall, morphological evidence shows that ancestral forms were small, colonial coelomates with a muscular body wall and a U‐shaped gut with ciliary tentacle crown, and were capable of asexual budding.

TLDR
The behaviour of the lateral cilia of the tentacles of L. crassicauda is described, and it is suggested that they are under the nervous control of the animal.
