 Cerithiopsis gemmulosa (C. B. Adams, 1850)  Gem Miniature Cerith

SEM photos from: Rolán, E., Lee H., Krisberg, M. & Fernández-Garcés, R. 2012. The Protoconch and Early Teleoconch Whorls of the Brownish Cerithiopsis (Mollusca, Cerithiopsidae) in the Caribbean and Adjacent Regions. Xenophora 139:11-16.


The following three images are of a specimen from Port Canaveral, Brevard Co., FL, that Harry and I both consider to be C. gemulosa, even though protoconch is of 4 whorls. From underside jetty rock. Sorry, size record lost.


This group image is of shells collected off the black sponge (Hymeniocidon heliophila), Mosquito Lagoon at Haulover Canal, Brevard County, FL (about 4-7 mm.) | Digital image by Marlo Krisberg.
