  • 1. A study of growth and age structure in a Connecticut population of Urosalpinx cinerea was carried out using both shell length and weight frequency analysis. A cumulative growth curve is proposed and compared with other published data for the species.2. Growth interruption marks (annuli) occur in Urosalpinx but are not as useful as in some other mollusks because of difficulty in discriminating annuli from interruptions caused by other factors.3. Close to seventy percent of maximum shell… CONTINUE READING
