The Amy Elizabeth (“Betty”) Blagg Collection of Bryozoa at the Museum of Comparative Zoology (MCZ) consists of 55 lots containing 33 genera (51 species) collected on the coast of California from 1936 to 1938. The collection was received at the Mu

The structure, attachment and subsequent metamorphosis of larvae of the marine bryozoan Bugula neritina were studied by light and electron microscopy. Two points of larval anatomy are of special significance to proper interpretation of the metamorpho

Embryos of the marine cheilo-ctenostome bryozoan Bugula neritina undergo a marked increase in volume (about 500-fold) during embryogenesis while being retained in a brood chamber. Previous morphological studies indicate that shortly after transfer of

The rapid morphogenetic movements that internalize the transitory larval epithelium and reorient the presumptive adult epidermis during the metamorphosis of the cellularioid cheilostome bryozoan, Bugula neritina, have been examined by light and elect

The coronate larva of the ascophoran bryozoan Watersipora arcuata has a ring of 32 large, multiciliated coronal cells that are used for swimming. Fourteen pairs of small cells are intercalated between the lateral margins of adjacent coronal cells. Th

A broadly based comparative study was initiated to assess components of the flagellar basal apparatus as a character set in phylogenetic analyses of poriferans. The flagellated (monociliated) epidermal cells of sponge larvae were selected for study.

The larva of the ascophoran cheilstome Watersipora arcuata is described on the basis of serial 1-μ sections, light microscopy of whole mounts, and scanning electron microscopy. Using lightly osmicated specimens, it was possible to map almost every c

The majority of bryozoans possess short-lived larvae with limited dispersal potential, yet many species of bryozoans have obtained global distributions. The marine bryozoan Tricellaria inopinata d’Hondt and Occhipinti-Ambrogi, 1985 was first descri

For sessile invertebrates, the degree to which dispersal mechanisms transport individuals away from their natal grounds can have significant ecological implications. Even though the larvae of the marine bryozoan Bugula stolonifera have limited disper
