SummaryThe fertilized egg of the freshwater bryozoan Plumatella fungosa develops into an elongated ovoid larva, which after embryogenesis in the embryo sack is released into the surrounding water. During the short free-swimming stage the larva is characterized by the presence of several locomotive and attachment cell types. The ectodermal epithelial cells are provided with numerous cilia. The cytoplasm of the epithelial cells contains numerous mitochondria, Golgi bodies, and ribosomes. Gland… Expand

Insights into the organization of plumatellid larvae (lophotrochozoa, Bryozoa) by means of 3D‐imaging and confocal microscopy
This study confirms previous interpretations that the apical plate pole does not correspond to the apicals pole of gymnolaemate larvae but to their oral side, leading to the suggestion that an apical organ is never formed and theApical plate compensates for its absence in the free‐swimming period.

The nervous system of the actinotroch larva of Phoronis muelleri (Phoronida)
All nerve cells were found in the apical ganglion and none was observed along the nerves, and sensory organs such as eyes and statocysts were not observed. Expand
Muscular systems in gymnolaemate bryozoan larvae (Bryozoa: Gymnolaemata)
Detailed morphological descriptions of the three-dimensional structure of muscular systems in the larvae of Flustrellidra hispida, Alcyonidium gelatinosum, Membranipora membranacea, Bugula fulva and Bowerbankia gracilis show muscular systems to be much more complex than previously recognized. Expand
Neuromuscular system of the larva of Fredericella sultana (Bryozoa: Phylactolaemata)
The separate origin of larval and adult serotonergic nervous systems, which remain unconnected is most likely ancestral and apomorphic for Bryozoa and argues for the homology of bryozoan larval forms. Expand
Evolutionary and Structural Diversification of the Larval Nervous System Among Marine Bryozoans
The results presented here indicate that neuronal pathways are largely ipsilateral, with more complex synaptic connections localized within the nerve nodule, and that cyclostome larvae maintain swimming and probing behaviors with sensory-motor systems functionally similar to those of some parenchymella and planula larval types. Expand
The morphology and evolutionary significance of the ciliary fields and musculature among marine bryozoan larvae
Overall, among the morphological grades of larval bryozoans, the structural variation and arrangement of the main cell groups responsible for ciliary propulsion have been evolutionarily decoupled from the more divergent modifications of larvals musculature. Expand
The soft body parts of freshwater bryozoans depicted by scanning electron microscopy
For the first time, special scanning electron microscopical preparation techniques, i.e. chemical dehydration and air drying with hexamethyldisilacane, were used to study the Phylactolaemata. ThisExpand
Serotonergic and FMRFamidergic nervous systems in gymnolaemate bryozoan larvae
The larval nervous systems of the four gymnolaemate species Flustrellidra hispida, Bugulafulva, Alcyonidiumgelatinosum, and Bowerbankiagracilis are examined by means of antibody staining against the neurotransmitters serotonin and FMRFamide, as well as against acetylated α-tubulin. Expand
Plathelminthes and Plathelminthomorpha — paraphyletic taxa
It is concluded that both taxa are paraphyletic assemblages, and the respective characters, as well as the implication for the proposed stem species of the Bilateria are outlined and discussed. Expand


The larval morphology of the marine bryozoan Bowerbankia gracilis (Ctenostomata: Vesicularioidea)
The oral polypide rudiment, the extensive pallial epithelium, and the reduced internal sac in vesicularioid larvae indicate that their pattern of metamorphosis also differs radically from the metamorphoses of other bryozoans. Expand
