Description:
Thalamoporella floridana is an encrusting species whose colonies sometimes rise into erect rosettes or frills. Colonies are gray to white in color, with individual zooids quadrangular in shape and of variable size. Typical zooid size is 0.02 - 0.22 inches in height, and 0.001 inches in width. Distinct grooves separate individuals. The frontal membrane covering the colony surface is lightly calcified but perforated.   Opesia are hoof-shaped. Avicularia between zooids are arch-shaped, and mandible points are bent.

Habitat:
Typical habitats for bryozoans in the Indian River Lagoon include seagrasses, mangrove roots, drift algae, oyster reef, docks, pilings, breakwaters, and man-made debris.  T. floridana is the most abundant species on the stems of the hydroid Thyroscyphus ramosus during the winter. It was also found encrusting rhodophytes at coastal locations and attached to breakwater rocks at Sebastian Inlet, where it forms large masses in January.  It occurs year-round in Florida, but is most abundant in the winter months.

Range:
T. floridana occurs from Cape Hatteras to the Caribbean. It occurs year-round within the Indian River Lagoon.
