Bryozoa are the least known in this respect. Here, we focused on the fine structure of the body cavity in 12 bryozoan species: 6 gymnolaemates, 3 stenolaemates and 3 phylactolaemates.

Conclusions. We are able to show distinct similarities among bryozoans in the formation of the different organ systems: a two-layered vesicle-like early bud, the ganglion forming as an invagination of the epidermal layer in between the prospective mouth and anal area, the digestive tract mainly forming as an outpocketing of the prospective anal area, and the lophophore forming from two lateral ...A Bryozoan's Medical Endosymbiont. The spiral-tufted bryozoan ( Bugula neritina) is being studied for a potential Alzheimer's disease and cancer drug—but it's not the bryozoan that makes the chemical.

Sometimes the skeleton is made of minerals, and sometimes it is made of chitin. Bryozoans are primarily marine, but are sometimes found in tidal or delta environments. Each animal in the colony is called a zooid.Morphology, Anatomy, and Systematics of the Cinctiporidae, New Family (Bryozoa: Stenolaemata) Richard S. Boardman Frank K. McKinney and Paul D.

The oldest known member of the familyBryozoa is a phylum of small aquatic invertebrates that filter feed with tentacles lined with cilia. Most species are marine and live in tropical seas, although many are in temperate or cold seas, and some live in brackish or freshwater. Of the ~ 4000 extant species, all but one genus is colonial.

Finally, bryozoans are hermaphrodites, that is, they have female and male reproductive structures. They reproduce in a sexual and asexual way, with internal fertilization and indirect development.

The form taken by bryozoan colonies can be highly variable, from gelatinous blobs to upright branching structures and sheet-like encrusters, but the general morphology of a zooid is similar across the classes. Bryozoans often resemble seaweeds (or mosses) with which they are frequently confused by the public. Alone among lophophorates, Bryozoa includes freshwater representatives. The lophophore may be circular or horseshoe shaped in cross section.

Despite having a similar bauplan, bryozoans are morphologically highly diverse and are represented by three major taxa: Phylactolaemata, Stenolaemata and Gymnolaemata.

Many bryozoans are polymorphic with zooids specialized for different functions. Gymnolaemata C Gymnolaemate bryozoans are almost entirely marine and have circular lophophores. No epistome and no body wall musculature are present. These are considered to be derived characteristics. Colonies are polymorphic with specialization of zooids.
