Offshore marine cheilostome Bryozoa from Fort Lauderdale, Florida

Abstract

Cheilostome Bryozoa were collected upon marine fouling test panels exposed offshore from Fort Lauderdale, Florida, USA between 1961 and 1967. Panels were exposed at certain depths, ranging from the surface to the bottom, in several arrays extending to a distance of 4 miles offshore. Twenty-three species were identified from the 114 panels recovered and examined. Most species were found on panels in shallow water, or on panels near the bottom in deeper, offshore water. A notable exception was a large, arborescent colony of Biflustra savartii which engulfed a panel 50 feet (15 m) deep, 4 miles from shore, in the Florida current. The lack of cheilostome Bryozoa on shallow and mid-water panels at the offshore, deepwater stations was apparently due to the low number of larvae reaching them from the distant inshore colonies.
