Flagellar basal apparatus and its utility in phylogenetic analyses of the porifera
The flagellar basal apparatus of sponges is more similar to that found in choanoflagellates than it is to that observed in eumetazoans, and a robust similarity in structure of the basal appartus is observed among the three species of halichondrids studied to date. Expand
A simplified placenta‐like system for the transport of extraembryonic nutrients during embryogenesis of Bugula neritina (bryozoa)
Embryos of the marine cheilo‐ctenostome bryozoan Bugula neritina undergo a marked increase in volume during embryogenesis while being retained in a brood chamber suggesting that the parent is involved as a source of extraembryonic nutrients required for the extensive growth of the embryo. Expand
Attachment and metamorphosis of the cheilo‐ctenostome bryozoan bugula neritina (linné)
The structure, attachment and subsequent metamorphosis of larvae of the marine bryozoan Bugula neritina were studied by light and electron microscopy.
Structure and swimming behavior of the larva of Haliclona tubifera (Porifera: Demospongiae)

  • 1 December 1993
Early developmental stages of Haliclona tubifera are retained by the parent and larvae are released on illumination of dark‐adapted colonies, and three stages of bacteriocytes are described based on anatomical criteria, presence of bacteria, and what appear to be stages in degradation of bacteria.

Effects of duration of larval swimming period on early colony development in Bugula stolonifera (Bryozoa: Cheilostomata)
This is the first report for any bryozoan that prolongation of the larval free-swimming period affects the rate of colony development. Expand
Association of bacteria with bryozoan larvae
Seven species of marine bryozoans were examined for the presence of bacteria associated with the larvae, and those bryzoans examined that possessed the bacteria-larva association are among the most frequently encountered fouling b Bryozoans. Expand
Structure and swimming behavior of the larva of Halichondria melanadocia (Porifera: Demospongiae)
Spicules and choanocyte chambers are somatic structures associated with adults, and their appearance in larvae is presumably a consequence of a heterochronic event, most likely acceleration, which awaits further developmental analysis and greater phylogenetic resolution. Expand
Population structure and connectivity in the Atlantic scleractinian coral Montastraea cavernosa (Linnaeus, 1767)
The results suggest that moderate to high gene flow occurs within and among populations of M. cavernosa in the Western Atlantic, suggesting that populations are also partially maintained through self-seeding and that gene flow may be restricted over large geographic distances. Expand
