Abstract
AbstractThe ecological record of bryozoans from the continental shelf–slope region of the southwestern Bay of Bengal is very sparse, prompting this investigation. Forty-five sea-floor sediment samples were collected along eight transects during the cruise—R/V Sagar Paschimi from the offshore region between Chennai and Cuddalore in the southwestern Bay of Bengal. The distribution of bryozoans was assessed based upon fragments of bryozoan colonies and their skeletal masses from these samples, which were collected at depths ranging from 10 to 350 m. The goal was to determine the relationship between environmental parameters measured from the study area and the abundances of various bryozoan morphotypes. The results revealed eight morphotypes of bryozoans, the most abundant being Cheilostomatida. The distribution of bryozoan fragments appeared to respond to changes in depth-related factors such as nature of substrate, turbulence and rate of sedimentation.KeywordsMarine bryozoansShelf-slope sedimentsDistributionChennai–CuddaloreBay of Bengal
